Biochemical logic drives microscopic shape shifters

  August 18/25, 2008
Combine pH-sensitive nanoparticles with enzymes that carry out the chemical equivalent of simple computer logic and you can bring nanoparticles together or move them apart in response to biochemical changes in their environment.

The biochemical self-assembly method could be used to make molecular devices that diagnose and treat diseases.
