Unformatted text preview: 1 It turns out that all of the information that man has carefully accumulated in all the books in the world can be writtenin a cube of material one two-hundredth of an inch wide. This fact---that enormous amounts of information can be carried in an exceedingly small space---is, of course, well known to the biologists Richard Feynman, December 29th 1959 Plenty of Room at the Bottom Biology is not simply writing information; it is doing something about it. A biological system can be exceedingly small. Many of the cells are very tiny, but they are very active; they manufacture various substances; they walk around; all on a very small scale. Consider the possibility that we too can make a thing very small which does what we want---that we can manufacture an object that maneuvers at that level! The evolution of technology? Biotechnology: using living organisms as factories. Micro-organisms are small, smart, and self-replicating nanotech Biomimetic approaches for improved materials and devices Can we mimic the way nature makes things? Bottom-up molecular construction Going beyond the limitations of nature Biomimetic Technology A strategy based on the principles of biological design. Not necessarily using biological materials or methods directly. Clicker Question Which is NOT an example of a biomimetic technology?...
