UCSD Chemists Use Tiny 'Chaperones' To Direct

Abstract:
Chemists at the University of California, San Diego have developed a method that uses dust-sized chips of silicon to surround and precisely direct the motion of molecules, cells, bacteria and other miniscule objects within a tiny drop of liquid.

Their development of these tiny silicon “chaperones” represents an important new achievement in the emerging field of “microfluidics,” in which new methods are sought to create, transport and experiment with ever smaller volumes of fluids.

“We call them ‘smart dust’ because their nanostructure can be engineered to give them rudimentary sensing, data processing, communication, and homing capabilities.”
