The word Nanotechnology was coined to describe nanometer scale engineering done by chemistry (self-assembly and catalysis). The idea is to build up structures by plugging their molecules together in the right order, which of course is what cells do. We were recently visited by Dan Nicolau, who is interested in nanotechnological patterning of proteins on surfaces. Dan came on a Royal Society Fellowship, and his wife Dana, who is doing a PhD in Science Policy, wrote an excellent appreciation, including hyperlinks, of the current state of physical chemical and biological approaches to molecular scale manufacturing: |
