    Nanotech: Beyond the Hype -- and Fear
    Kristen Kulinowski's job at the Center for Biological & Environmental Nanotechnology is "to draw attention to proactive, responsible development"

    In recent years, an eclectic band of scientists has mapped out a new frontier known broadly as nanotechnology. Though they're from different traditions and methods, these explorers, who include biologists, chemists, physicists, chipmakers, and computational experts, have tackled the same basic question: how to control the building blocks of matter from the bottom up.
    Advertisement

    They're learning how to guide individual atoms as they combine to form molecules and, in turn, how to make materials -- molecule-by-molecule -- that don't exist in nature. Their work cuts across some of the hottest areas of science, including innovative drug-delivery systems, cancer treatments, ultrastrong lightweight metals, and mass-produced superconducting wires -- to name a few.

    Nanotechnology is surrounded by hyperbole, for good reason. It arguably shows as much promise in both science and business as any other major technology of the past century, including nuclear energy in the 1950s or genetics in the 1990s. Yet before business rushes headlong into a nano-tomorrow, an assessment of the risks nanotechnology poses to public health and the environment needs to be done. Just as nuclear waste and the flap over genetically modified foods tainted the promise of what were supposed to be transforming technologies, many people are concerned that nanomaterials could create problems if introduced without thorough testing.

    LESSONS LEARNED. Kristen Kulinowski is uniquely positioned to help separate nanotech hype from reality. As a chemistry faculty member and executive director for Education & Public Policy of the federally funded Center for Biological & Environmental Nanotechnology (CBEN) at Rice University, she believes that scientists are applying the lessons learned from past disappointments. Well in advance of major commercial production, testing of nanomaterials on living organisms is under way in university labs. And already, federal agencies such as the Food & Drug Administration and the Environmental Protection Agency are exploring regulation that will help ensure that commercialized nanotech is more a dream than a nightmare.

    Kulinowski does have concerns that in the near term -- before the basic science is even ironed out -- nanotech research could be derailed by outside factors. Already, nascent signs of dot-com style hucksterism are appearing, with companies making nanotech claims of dubious scientific merit. Conversely, Kulinowski adds, others are fearful of the perils of nanomaterials without understanding the underlying science.

    BusinessWeek Industries Editor Adam Aston recently met Kulinowski in Houston, where she talked about some of nanotech's most promising areas and her commitment to help inform public understanding and policy this new area. Here are edited excerpts of their conversation:

    Q: What worries you about the public's response to nanotechnology?
    A: I'm worried about an overreaction to both the hype and the fear. Every time a research article comes out talking about a certain type of risk, a dozen high-profile media stories ring alarm bells but fail to explain all the nuances of the study -- that results need to be repeated, or that concentrations of nanomaterials used in lab studies are unlikely to occur in nature. This sort of alarmist coverage can affect lawmakers as well as the public.

    So one of my jobs is to help inform science policymakers in Washington. Likewise, the reactions to positive stories can be overdone -- driving unrealistic expectations about miracle cures or how soon new nanomaterials may be available.

    Q: What are the real risks?
    A: There are two broad categories of risk assessment going on right now. One is in biological systems -- starting with the effects on individual cells and up to more sophisticated organisms such

      The reason the viral coat proteins self-assemble is that this is the most thermodynamically favorable state for these proteins in the aqueous environment in which the virus is replicating... i.e., the cell. The proteins have evolved such that their specific amino acid compositions make the assembled state most favorable. I suppose this is a valid analogy to what some nanotechnology research is tryin gto accomplish.

      However, the proteins don't copy themselves and then self-assemble. The proteins are translated from the genetic material of the virus (DNA or RNA), and then the proteins self-assemble. The machinery that does this translation is most often provided by the host cell.

      This is practically identical to how the cell itself replicates, although on a smaller scale. The genetic material is translated into proteins that can do the work required to make a new cell (copy the DNA, synthesize or import the lipids needed for the membrane, synthesize the proteins needed, and so on).

      Sometimes, there are even special proteins called chaperones that help other proteins adopt their "correct" structure. I do not actually know of a case where this happens for viral proteins, but it wouldn't surprise me if one exists.

The same goes for machines copying the human brain's ability to do arithmetic.

      Extend this pattern to self-replication and intelligence and the results could be truly scary indeed. Eventually we will find ways to copy these two abilities of nature, and before long may have technology for intelligence and replication that is orders of magnitude better than that provided by nature originally.

    Next is the ability to reprduce using simple matter, I mean, a lab is a very different enviornment then the real world, we'll probablly see self-replicating nano-machines that work in specifically temperature controled vats long before we see ones that can do it in the real world: Why, even if you can get a machine so sofisticated that it can tear apart simple carbon atoms, and whatever else it needs (and figure out what's carbon and what's not) and build a copy of itself, it's likely to loose it's tiny manipulators with every major temprature change, as the particles grow and contract while it tries to move them along!

    Next someone will have to be able to get a hold of these things, and reprogram them to do somethign bad (that may actually be the easiest part: as all you have to do is REMOVE code that will be telling them to do other things besides replicate), but it will still require a multi-billion dollar lab to access there tiny circutry and reprogram them on such a basic level (the equivalent to taking out chips in a modern computer, but requireing a nano-manipulator!), so this is not something a 'backyard terrorist' is going to do, and if a government dose it, they will put a reasonable 'off' time in them, which will probabally put them into the same catagory as other WMDs. But even if they did not, it would still be vunerable to the same fighting techniques I outlined above

    Please note, this is the same essay on grey goo I used before- but it still applies!

  48. more misunderstanding of nanotech physics/chemistr by Daetrin · · Score: 2, Insightful
    Wow, so much mis-information. You're right that designing nanotech that would be able to survive and reproduce in the world would be difficult, but if that hurdle was passed they wouldn't be as easy to destroy as you make out.

    They're not going to rust. First of all, they probably won't be made out of iron, they'll probably be made out of carbon, oxygen and hydrogen. The chemical bonds that are necessary for oxidation or any other kind of reaction are already being used to attach the various pieces of the nanotech together. If there are no free electrons or "holes" nothing else is going to latch on. In effect, it's already "rusted."

    What makes you think they'll have computer circuits that could be affected by an EMP? They could just as easily be using rod-logic or something similar.

    As for "diamonds" being brittle, not at the scale we're talking about. The type of sound waves needed to break carbon bonds at a microscopic level would destroy just about anything else as well. What do you do if a person gets affected? Shooting at them with a beam of something that breaks all carbon bonds is _not_ a good solution.

    Why would moderate temperature changes cause them to break? You can get large structures to break by changing the temperature repeatedly, but that takes a long time, and it's because of the aggregate expansion of all the molecules inside. Small structures, such as the cells of our body for instance, don't fall apart from the stress of small temperature changes. You can denature proteins and set stuff on fire if you make things hot enough, but that's because of chemical changes, not expansion/contraction.

    Oh, and depending on the nature of the nanotech "reprograming" them might be difficult or impossible. They might only be capable of the specific task they were designed for if they have physical logic rather then reprogramable circuits. That would make terrorism much harder, up until the point technology advances enough to let anyone with a home lab cook up some nano-tech. In terms of grey-goo the biggest threat will probably be programming error, followed by mad scientist, followed by terroists.

    Of more pressing concern is possible enviromental dangers (potentially very serious when one of the possible enviroments is your body) and smaller malfunctions. It's a quite possible for nanotech to screw up and kill you in a way that doesn't involve grey-goo or threaten the rest of the planet.

    Anyone with common sense knew everything stated in this interview.

It says nothing about nanotechnology other than the fact that it exists and that there's a chance it's not all that dangerous.

  51. Re:more misunderstanding of nanotech physics/chemi by strider_starslayer · · Score: 1

    I cannot specifically refute your comments, however many of the things you outline do not apply to a 'grey goo' scenario (a scenario where a bunch of self-replicating nanomachines go haywire dissasembling and self-replicating out of control until they reduce the entire planet into 'grey goo')

    they'll probably be made out of carbon, oxygen and hydrogen. composites of carbon, oxygen and hydrogen are normally rather suseptible to heat (I won't say that no structure consisting of hydrocarbons is not immune to heat- but I can't think of one; then again, I'm not a chemist)

    As for "diamonds" being brittle, not at the scale we're talking about. The type of sound waves needed to break carbon bonds at a microscopic level would destroy just about anything else as well. What do you do if a person gets affected? Shooting at them with a beam of something that breaks all carbon bonds is _not_ a good solution. While I admit that sound waves powerful enough to fry diamond nanomachines would likely make a mess of a human (unless something very specific with frequencies is done), but given the option of messing up a few humans who are allready screaming in agony as all there raw materials are processed to make new nanomachines and saving the world against just watching them scream in agony and spread the plague to others; I think even the humans screaming in agony would agree that it's a good idea to turn the sonic guns on them, the most important part about a sonic weapon is that it won't 'scatter' a few survivors like an explosive would, rapidly allowing them to rebuild over a larger area then before

    What makes you think they'll have computer circuits that could be affected by an EMP? They could just as easily be using rod-logic or something similar. Well EMP is just one option for eletrically conductive nanomachines (if there rod logic but conductive then the small scale electric arcs that an EMP causes inside them will likely destroy them as well), UV for hydrocarbon/optical based ones, maby some form of rod movement inhibitor for rod-logic (I admit I've no idea how that would be done)

    Why would moderate temperature changes cause them to break? You can get large structures to break by changing the temperature repeatedly, but that takes a long time, and it's because of the aggregate expansion of all the molecules inside. Small structures, such as the cells of our body for instance, don't fall apart from the stress of small temperature changes. You can denature proteins and set stuff on fire if you make things hot enough, but that's because of chemical changes, not expansion/contraction. It only takes a difference of 6 degreess (celcius) to reach an opperating temprature in a human body that will not support life for long (though you may argue that any nanomachines we create for the real world will have far better 'room temprature' constraints then the internals of a human body, and I woulden't complain). More of a problem would be difference of temprature along monomolecular manipulators (as I understand it a nessessity for the nano-machines to manipulate the atoms required to put together copies of themselves), since the manipulators will come to a 'point' which is only one molecule or perhapse one atom in size anything that makes the 'tip' of the blade break free (like being energized by an impact with a high energy particle- also known as 'heating up suddenly') will set it free 'chipping' the blade, it won't (in my mind) take many chips for the manipulator to become ineffectual. And by 'small change' in temprature, I'm talking about the sort of change that a microwave gun, or flamethrower would be able to introduce to them (a rapid change in the tens to hundreds of degrees celcius)

    Now I fully admit that I MAY be wrong, my background is engineering and computers (and I'm still a student), not chemistry; so I'm relying on high school chemistry, biology, and a littel bit of personal interest research for a bit of this- any chemists or people who know more then me about chemistry are free to disagree, and I'll acceep a logically grounded opinion that outmanuvers mine.
