Nanotechnology

iConrad writes "I first found this book on EDN which described it by saying, 'It collects many ideas about what nanotech is doing and has the potential to do without the breathless hype.' I've read the Drexler books and pretty much everything else I can find about nano, so I already know that nano will save the world, replace humanity, etc., etc. (Sigh.) What I didn't know (and I think this book really told me) is what nanotechnology really is, what it is doing right now, what it will mean for businesses, and why I should care." Read on for the rest of iConrad's review. Nanotechnology: A Gentle Introduction to the Next Big Idea author Mark Ratner, Daniel Ratner pages 188 publisher Prentice Hall rating 9 reviewer Conrad ISBN 0131014005 summary A (mostly) non-technical introduction to nano

In other words, I started this book very skeptical, but it convinced me. I don't know how many of you have heard of Mark Ratner, but he is credited with being the first to speculate on using individual molecules as components in electronic circuits back in 1974. If you read about molecular electronics now (or go to any moletronics conferences) you'll see his name come up constantly. He is also associate director of the nanotech institute at Northwestern University, the first dedicated nanotech center in the country. This is not like reading a lot of the books out there - he really knows his stuff.

The book starts with a general introduction, talks about hype, nanobots, and the big budgets that are out there for nanotech research. It opens a lot of questions, including ethical issues and a little bit of skepticism which I think is very healthy for a science which promises a lot, but has yet to truly distinguish itself.

After the introduction, there is a chapter which gets to the heart of matters -- it explains that nanotech is not just the ultimate level of miniaturization, but that it is special since it is at the interface of bulk properties, quantum properties, and the key elements in life processes (such as DNA). It also sets the stage for the heart of the book -- chapters on tools for the nanosciences (ever wonder why nano wasn't real until now even though Feynman started talking about it in the 1960s?), a grand tour which will quickly dispel any illusions that nanotechnology is all about nanobots a la Bill Joy and Star Trek, and chapters on smart materials, biomedical applications, sensors, optics, and electronics. There is also recap of some basic science, but not many Slashdotters will need that.

While the hype may not be breathless, these chapters left me that way. What the Ratners discuss is real, in context, and discussed intelligently and thoughtfully. They gave me enough science to explain what they are talking about but not enough to distract me and they include a dash of some appropriately wry humor to lighten things up. There are illustrations throughout and a color inset in the middle. The illustrations are clearly from lab work -- their quality varies significantly, but I found them very useful indeed.

One of my favorite aspects of the book is the sidebars -- there are sections on DNA computing, quantum computing, swarm computing, nanotubes, lab-on-a-chip, and other applications. These are short, sweet, and, as always, to the point.

The book ends with two chapters on business and ethics. Unlike most nanotech books I've read, there was some substantial thought here. Ethical issues such as intellectual property concerns as well as health issues were treated at some length. The book doesn't come to conclusions on these points -- it attempts to present a balanced discussion and actively encourages readers to enter the debate. The business section was obviously written by someone who lived through the dot-com bubble (I'm guessing this was Mark's coauthor, Dan). Some of the points were obvious, but the analysis for investors is something well worth reading (attention VCs!) and again, the authors set the sights at a reasonable level. They point out that there are fortunes to be made, but not by accident. They also make some predictions about where the money is.

My only complaints about this book were that a few of the pictures were not of ideal quality, and that the companion web site wasn't very exciting (though they promise to update it.) All in all I found the book to be an ideal mix of technical and non-technical, a superb survey of a complex field, and an interesting read throughout. It leaves all of the other "introduction to nano" books in the shade -- perhaps because it is written by a pioneer in the field as well as someone who has thought about how to make it pay. I considered it required reading for anyone who wants to understand what nano is really about.

      That's not a dumb question. It's the main reason that free-floating assembler nanobots probably won't work. They have the same energy constraints as biological life. Biology can build big, solid objects like trees, but it takes years. Drexler used to talk about vats of nanobots building things like rocket engines, but that takes real power and it has to come from somewhere.

      Nanomachines on an IC substrate, attached to external power, look much more feasible.

      Chemical storage and conversion of power is pretty scalable - I mean, our cells contain mitochondrial power plant organelles which are pretty darn small. But it is a reasonable issue to bring up - the more "fuel," of whatever variety, a self-contained nanomachine has to carry, the less "nano" it is. Or else it has to have some kind of refuelling station. Something might be done with solar (the chloroplast, again, is pretty nano-scale) but we're a long way off of effective solar power generation at the nano scale. This does inject some reason into the whole "nanobots amock," "grey goo" fears some have of nanobots wreaking havoc on all things. The laws of physics put some serious constraints on what a very tiny thing can acheive (the virus, for example, can't do anything without subverting your big ol' ponderous body's equipment for replication - itself another level of caution, because sometimes it's not what the little thing can do but what it could make other things do...)


      However, in a lot of applications I think this is probably a moot point, as nanoscale devices will be components of other devices rather than stand-alone machines, and will thus access the powergrid of the conventional scale device. I mean, sure I want a quantum computer in my cell phone so it can guess who I want to call before I'm finished deciding and save me precious seconds. But I don't want my cell phone to actually be nanoscale. Damn things are on the edge of ridiculously small as it is.

      biology, or rather evolution, has come up with some fairly novel ways for cells to create energy, ie. metabolize stuff via reduction, etc. cockroaches don't seem to have any problem, do they?

      reproduction, on the other hand, probably isn't desired of nanobots. certainly not uncontrolled reproduction (ask Bill Joy ;). biological organisms spend huge amounts of energy on reproduction. lift that requirement and the bot may be able to scavenge enough to survive.

      when it comes to building jet engines, or any other large or complicated thing, the interesting thing is more likely cell lineage, like in biology. see the nematode for a good example; its entire cell lineage is known. how would these nanobots know how to assemble into something useful?

      Right. And "free-floating" nanobots wouldn't have to spend as much energy scavenging, either. It's not like they'll just be dumped into a vat of seawater; presumably fuel/nutrients will be provided as relatively ready-to-hand as the materials they'll need to build whatever they're gonna build.

      Substrate-based molecular manufacturing is probably more straightforward (and therefore may happen first). Free-floating molecular manufacturing may end up being more flexible (and therefore also worth working toward). Actually, what may end up being best is a mixed approach, some kind of substrate-in-soup thing, and/or different approaches used for different desired results.

      Besides which, does anyone know how long it takes to make a jet engine now, starting from raw materials? Weeks? Months?

      This seems pretty exciting to me. Since it would run off of reduction/oxidation states, one could recharge in with a chemical reaction, light, or just by applying a voltage accross the solution that the machines are in. Yeah, so this seems pretty promising, although a long way off.
