Nanotech Products Hitting the Market
stdin writes "Saw this on SFGate. Nanotech's first fruits are nearing the consumer market." Not little machines, yet, but a variety of products using very small components.

Plug these numbers in and you'll find that even if the propellant consists of a single atom the forward velocity of the nanobot will be somewhere in the region of 1/100th of the speed of light. That may not sound like much, but even 1/1000 * 3e8 m/s = 3e5 m/s = 300 km/s = 1080000 km/h!
The sunscreen's manufacturer (represented by one of its lead investors) says the company has mastered the task of making reliably miniscule particles of a substance that can block out the sun's harmful ultraviolet rays.
Hair dye, anyone?
Whenever I go to Wendy's, the amount of fries I get in my "Biggie" fry borders on nanotechnology I would say.

Hair dye!? What happened to the army of nanobots that will march across my scalp, planting each and every individual hair in its own designer follicle and touching up the paint job on the rest? There goes my dream...
Yeah, yeah. Nano-techno sunscreen and hair dye blah blah blah. Where are the freakin' robots already?!?
Imagine.. tiny, tiny apples..
Wait don't eat that apple, that's my Web Server!!!
"We need to see a technology that can lead to real products," explained Zwi Vromen, whose Israel-based Millennium Materials Fund has made 19 nanotechnology investments to date."

If silicon micromachines are considered nanotech, these products have been commercially available for years: microfluidic valves, accelerometers for airbag systems, the DLP (digital light processor) from Texas Instruments that is the basis of many video systems.
Manufactured products are made from atoms. The properties of those products depend on how those atoms are arranged. If we rearrange the atoms in coal we can make diamond. If we rearrange the atoms in sand (and add a few other trace elements) we can make computer chips. If we rearrange the atoms in dirt, water and air we can make potatoes. Todays manufacturing methods are very crude at the molecular level. Casting, grinding, milling and even lithography move atoms in great thundering statistical herds. It's like trying to make things out of LEGO blocks with boxing gloves on your hands. Yes, you can push the LEGO blocks into great heaps and pile them up, but you can't really snap them together the way you'd like.
In the future, nanotechnology will let us take off the boxing gloves. We'll be able to snap together the fundamental building blocks of nature easily, inexpensively and in almost any arrangement that we desire. This will be essential if we are to continue the revolution in computer hardware beyond about the next decade, and will also let us fabricate an entire new generation of products that are cleaner, stronger, lighter, and more precise.
It's worth pointing out that the word "nanotechnology" has become very popular and is used to describe many types of research where the characteristic dimensions are less than about 1,000 nanometers. For example, continued improvements in lithography have resulted in line widths that are less than one micron: this work is often called "nanotechnology." Sub-micron lithography is clearly very valuable (ask anyone who uses a computer!) but it is equally clear that lithography will not let us build semiconductor devices in which individual dopant atoms are located at specific lattice sites. Many of the exponentially improving trends in computer hardware capability have remained steady for the last 50 years. There is fairly widespread confidence that these trends are likely to continue for at least another ten years, but then lithography starts to reach its fundamental limits.
If we are to continue these trends we will have to develop a new "post-lithographic" manufacturing technology which will let us inexpensively build computer systems with mole quantities of logic elements that are molecular in both size and precision and are interconnected in complex and highly idiosyncratic patterns. Nanotechnology will let us do this.
When it's unclear from the context whether we're using the specific definition of "nanotechnology" (given here) or the broader and more inclusive definition (often used in the literature), we'll use the terms "molecular nanotechnology" or "molecular manufacturing."
Whatever we call it, it should let us
Get essentially every atom in the right place. Make almost any structure consistent with the laws of physics and chemistry that we can specify in atomic detail. Have manufacturing costs not greatly exceeding the cost of the required raw materials and energy. There are two more concepts commonly associated with nanotechnology: Positional assembly. Self replication. Clearly, we would be happy with any method that simultaneously achieved the first three objectives. However, this seems difficult without using some form of positional assembly (to get the right molecular parts in the right places) and some form of self replication (to keep the costs down).
The need for positional assembly implies an interest in molecular robotics, e.g., robotic devices that are molecular both in their size and precision. These molecular scale positional devices are likely to resemble very small versions of their everyday macroscopic counterparts. Positional assembly is frequently used in normal macroscopic manufacturing today, and provides tremendous advantages. Imagine trying to build a bicycle with both hands tied behind your back! The idea of manipulating and positioning individual atoms and molecules is still new and takes some getting used to. However, as Feynman said in a classic talk in 1959: "The principles of physics, as far as I can see, do not speak against the possibility of maneuvering things atom by atom." We need to apply at the molecular scale the concept that has demonstrated its effectiveness at the macroscopic scale: making parts go where we want by putting them where we want!
The requirement for low cost creates an interest in self replicating manufacturing systems, studied by von Neumann in the 1940's. These systems are able both to make copies of themselves and to manufacture useful products. If we can design and build one such system the manufacturing costs for more such systems and the products they make (assuming they can make copies of themselves in some reasonably inexpensive environment) will be very low.
If we don't fight for ourselves no one will.
I want to make sure that we have that nanotechnology ready in case those borg terrorists show up again. I'm not counting on the Borg forgetting to close up that "sleep" backdoor that witty androids hack into using an unsecured terminal that calls itself Picard.
While these may seems trivial, I can think of at least one product not mentioned here that may benefit from this:

When most people think about nanotechnology, they usually conjure images of microscopically tiny contraptions such as the invisibly small submarine that was injected into a character's bloodstream in the classic 1966 sci-fi movie "Fantastic Voyage."
Actually, I think Innerspace was better (you know, the one with Meg Ryan, Dennis Quaid, and Martin Short?).

I enjoyed the article. It makes an interesting point very clear, that nanotech is showing up first in rather technologically boring places. Converse to all the visions I've heard of self-assembling machines and the like it is a real technology that is being used for real applications.
I've heard increasingly frequent use of nanoscale devices in the Bio arena and for medical purposes, but far from the "submarine" concept. One of the more interesting ones was in a Scientific American or Science News article recently (can't find the article) talking about a small square chip that makes thorough and useful chemical tests doable in one step instead of hundreds of seperate ones. Imaging the chip using a basic camera provides a detailed readout on the exposure of many thousands of tests. Another interesting application involves carbon nanotubes, a much touted revolution in circuit building and such.
It seems that many people (geeks included) have been spouting the broader, long term vision of building complex nano machines that invade our bodies or self replicate, it's refreshing to hear a realistic perspective on nano technology.
Although I do admittedly get tired of the constantly pro-tech mindset that occurs in these articles, how about someone mentioning the detriments of these technologies occasionally? (grey goo theory anyone)

Uh Oh.
Umm, forgive me, but I don't think the "gray goo" syndrome referred to the stuff you squeeze out of a bottle of sunblock.
So, what exactly is your problem? Sounds like a pretty decent life.
The advances mentioned in the article seem to be improvements in grinding substances finely. The article claims that there is some kind of continuum from this grinding to actual nanotech machines, and that cautious investors are starting at the easy end of the continuum.
I don't see how this could be. It seems that if you want to approach the kind of nanotech described in Stepehenson's The Diamond Age you would probably work with tiny machines and assembly techniques and gradually push the size envelope downwards - which is how it happened with silicon. Or work with subtractive etching techniques that could remove material to leave behind movable parts. Merely grinding up tiny nondescript particles - in other words soot or dust - doesn't seem like a step on this road at all.
Of course my understanding of nanotechnology is firmly grounded in science fiction.

Perhaps this is a serious cry for help ...
- get more hours at the coffee shop. Start earning some money and some self-respect.
- stop wasting your time on silly computer stuff. Either do something productive such as web-pages, programs, or server configs, or log off
- take better care of your body; you'll feel better and people won't cross the street when they s(m)ee(ll) you.
- sign up for some courses in anything you like. Meet real people who have similar interests.
- do stuff around the house to help your parents. They're paying your bills, so show some responsibility and do your share.
- volunteer for something.

I want nano*hair* that can change colors at my whim. Length would be nice, too, but that'd involve replication I suppose, and evil terrible crises that would destroy the planet in a wave of nano-boffing. Or something.
(At the least, I'd like some hair dye that doesn't suck. Gods below, I'm all for multicolored hair, but not florescent crap.)
There are *many* safe and effective contraceptive devices (both to prevent disease transmission and pregnancy).
If pregnancy, alone, is your concern, the birth control pill and related drugs (shots; patches; etc) are *highly* effective when used properly.
Preventing disease transmission, also, isn't that difficult - barrier protection, such as latex condoms (both male and female), are *slightly* less effective when used properly and consistently than hormonal contraceptives at preventing pregnancy *but* they do provide significant (while not perfect) protection against disease transmission.
Of course, when possible, just choosing partners who are at low risk and are known not to be infected by any STDs is safer and more effective (if *slightly* more difficult).
YHL, man. I'm sorry.

I already use products that are essentially nanotech. For instance, an electronics project of mine uses an Analog Devices ADXL202, a two axis accelerometer that uses MEMS technology to measure acceleration. It's amazing stuff, they took a device that used to be the size of a big box and made it small enough so that 5 can fit on a dime. The nano-tech part of it is that all the moving parts that were in the original accelerometers have been replaced with a tiny series of tuning fork-like assemblies measured in nanometers that somehow impart movement information on an almost molecular scale.
Saying that, there is action around. For instance, want to buy the raw materials for building your own nanomachine? Try buying in bulk from http://www.nano.qinetiq.com/
With the action around, fast forward to 2010 and you start to see the real ramp up of the nanotech revolution. Quite what that will do to the world, who knows? But its nothing to the impact of Von Neumann nanomachines...
Does anybody remember when Wesley let a bunch of nano-bastards loose - and they multiplied like crazy, eating the computers and forming a big neural network that could talk?
Yeah, that's about as much as I know about nano-technology - and this article didn't really help.

nanotechnology was called miniturization. Ahh... those were the days. I wonder when some marketing droid will decide to rename microprocessors to nanoprocessors.
Uh, I thought newton's laws broke down when dealing with extreamly high velocities and/or tiny distances.

Just heard some sad news over at msnbc.com. Punk Rocker Dee Dee Ramone was found dead in his home this morning. He apparently died of a drug overdose. Even if you didn't like his music, there is no denying his contributions to punk rock. Truly an American icon.
Appreciate the warning, but I knew the potential trolling. Problem is, I've known a couple people like that and my Christian upbringing sometimes gets the better of me.
Only when we embrace the full potential of the Open Source community can we withstand the impact of lack of standards by MS.

There was a nanotech product I wouldn't mind owning :->
I expect that if the nanotech which has been described is accomplished, a sunscreen which applies itself is the obvious overengineered sunscreen.
And as aluminum is a very common element, I wouldn't be surprised at a fad of silver-coated beachgoers. Quickly followed by Halloween costumes that make you resemble the liquid Terminator...
Then I realized the self-evident. I'm one of those tries-to-be-cool-by-dying-my-hair nerds. The sunscreen? I'm as pale as a ghost, so even though I hate the sun, I can now bear it!

In case you're not too familiar the intricacies your physics (or your spelling:) this is a troll. My own physics isn't perfect and I might have some mnior details slightly off but I have taken several first year physics which is sufficient for the purpose of debunking this troll. Aside from the fact that he doesn't actually give any numbers lets look at a more accurate description of thrust. Thrust is more or less caused by impulse, this is the change in momentum of an object. When a particle goes out the back of an engine the velocity to which the impulse will accelerate that craft is described by the equation McVc=MpVp (c=craft p=particle). Therefore if you start from motionlessness and have a particle of propellent shooting out the back at 1/100000 c (c = speed of light) or 3000m/s, your craft made of 10 particles of the same mass will go at 1/1000000 c or 300m/s not 300 km/s as he would have you believe. Keep in mind also that I have chosen a very large value to shoot out my particle and the engineers could easily shoot their propellent on the scale of nanometers per second which would result in very manageable velocities. The only problem I could see is in storing propellent, it is much more likely that they would have some sort of electrical motor to drive legs or something like that. There could be some errors in my calculations or in the equations I used, if you find errors please post corrections, but I can assure you that the above post is a troll (I ran into one of his a while ago where he invented what can only be described as the opposite of an event horizon:).

See a psychiatrist. They can address whatever issues are causing this anti-social behavior. The clinical term for the disorder would likely be "OCD", that is to say, obsessive compulsive disorder. This can be controlled with medication. It is characterized by a compulsive feeling of necessity to perform repetitive, seemingly pointless tasks.
The very demographic that has been salivating over nanotechnology is the same demographic least likely to use the sunscreen it has produced. The only thing more ironic would be some sort of nano-technology condom.
It's quite unfortunate that your humorous observation was moderated down.

The DLP chip family from Texas Instruments have up to 1.3 million moving mirrors for high luminance TV projection systems for conference rooms, home and theatre digital TVs. These have been on the market for four years. This is nano tech if I ever saw it.
Better examples of nanotechnology or microtechnology than the ones found in the articles have been around for years and years:
Harddisk drive heads
Microprocessors
DNA arrays
Genetically engineered organisms
LCD screens
Engineering of better chemical catalysts
Arrays of micro-mirror for projection displays
Integrated optical switches
Ink jet printer heads

Is biology. Billions of years of evolution have propeled biological systems to a local optimum in terms of nanomachines that could be made from carbon based molecules.
Are there other optima based on different materials and/or manufacturing and design techniques? These questions are critical to the future of nanotech. As yet, no one has the answer.

Everyone is trying to jump on the bandwagon to get easy access to funding and as a marketing ploy.
Until we have a real Nanotech product I ask the moderators to filter out such marketing hype and save us reading things that are in actuality of no intrest to those wanting REAL NANOTECH.
This type of thing will actually dissapoint those who have been told about all the wonders of nanotech only to find some new dodgy hairdye is the type of thing to expect.

So you see we are poised to be the leader in nano fruit creation. Leveraging our high tech nano-enabled orchards or our "green tech" as we like to call it - we can have the highest quality output available in the US today. We focus on our core-competancies and get our arms around the solutions of the future in nano fruit production. By getting mind-share through advertiusing with strategic partnerships we will soon be the standard in quality fruit. Our b2b network supports a global fruit production infrastructure which can produce product on a scale that will put our competitors far behind.
Our seed funding was provided by the US goverment through a seed bill - the "US anti-terrorist new business development fund" which provides funds to new companies who develop products that can aid in any form with the fighting of terrorist in this post 9-11 economy. Our nano fruit growing technology is used in our "Fruit for the Troops" program to feed troops and refugees displaced by the terrorists in the US and abroad.
We are looking to raise 15 million in capital by Q2.
I think the greatest impact this technology will have on humanity is being able to provide food, medicine, clothing and reclaiming 100% of material waste. We will take the shit we flush down the toilet and make apples of it without screwing up the environment!
intel plans to use similar nanotechnology to create a processor, scheduled 6 years from now, to run at 20 ghz switching on and off at 1.5 trillion times/sec
Ralph's agenda is long term. We'll get there eventually, but before we do, we'll spend a lot of time puttering around with simple bacteria. Tom Knight is already starting that effort, which he calls microbial engineering. This is very cool, commendable work.
But there are limitations. You can make cells do logic operations, but they do them very slowly. Each cell has a very limited number of usable state variables. As long as we are starting with life, we are stuck with the limitations of cells. Cells can easily be programmed to make proteins, which don't have very desirable material properties, but to make more interesting stuff like tooth enamel or spider silk you need much more cleverness.
What's nice about cells is that they are inexpensive replicators that work today. What's bad about them is that humans never got a vote on the basic design, simplicity was never a design goal, programming them is hard, and the range of things they can be programmed to do is limited.
Ultimately we want a human-designed replicator that comes with a manual, is easy to program, and can do lots of different things.

When the coloring chemicals, known as pigment, are tinier, they likewise cover surfaces -- in this case hair -- more evenly. The results are dyes that should eventually last at least twice as long as those now sold.
But I need to redo the hair when the roots start showing, not when the colour fades...
I always considered the DLP chips used in video projectors (that have millions of pivoting mirrors on a silicon chip) to be an application of nanotech
Is there something about DLP that disqualifies it?
Firstly, I don't know how he arrived at his figure of 1/100 speed of light, is he joking when he says it doesn't sound like much? However using his velocity, by simply considering conservation of momentum, with a nanomachine of ~100 x the mass of the propellant atom (within his size range). The single expelled propellant atom would have to be traveling at the speed of light!! For more massive nanobots, light speed would have to be exceeded! Remember Einstein? Special Relativity ring a bell? You run into all sorts of problems, like your propellent having infinite mass and travelling back in time (if light speed is exceeded). Not to mention the fact that to accelerate the atom up to light speed would take an infinite amount of energy! Secondly. the sort of propulsion that he seems to be talking about is a chemical reaction producing the controlled explosive vapourisation and expulsion of a liquid or solid propellant. How this would work at atomic dimensions with a single atom of propellant, and containment problems I dont know. Thirdly, nanomachines will probably have more like the order of 10,000 -100,000 atoms i.e complex organic molecule sized, not atom sized. Specially if they have to perform complex tasks. Fourthly, there are other ways of propelling a nanomachine apart from the rocket engine approach, in the macroscopic world take cars, people etc. Nanomachines will probably be driven by chemical reactions like the hydrolysis of ATP. It is unlikley that nanomachines will carry their own fuel. Take molecular motors (dynein, kinesin, myosin) these are essentially biological nanomotors ~40 Nm and are activated by the presence of ATP in their surrounding environment. These or similar synthetic structures may well be used to provide the motive force behind nanomachines. Fifthly, most nanomachines will probably not be individually directed and powered. They are more likely to use redundancy in numbers and random effects such as brownian motion to get them were they need to be. I could go on....
