Massively parallel manipulation of single cells and microparticles using optical images

Article Abstract:

An optical image driven dielectrophoresis technique that permits high-resolution patterning of electric fields on a photoconductive surface for manipulating single particles is presented. The results suggest that with direct optical imaging control, multiple manipulation functions are combined to achieve complex, multi-steps manipulation protocols.

Self-assembly of amphiphilic dendritic dipeptides into helical pores

Article Abstract:

A library of amphiphilic dendritic dipeptides that self-assemble in solution and in bulk through a complex recognition process into helical pores is illustrated. The results depict that supramolecular dendrimer chemistry allows the controlled design of a range of periodic non-biological porous structures forming in solution and as films.

Asymmetric pores in a silicon membrane acting as massively parallel brownian ratchets

Article Abstract:

Research demonstrates that application of a periodic pressure of zero mean value to a basin separated by a macroporous silicon membrane, a rachet device containing one-dimensional pores, induces a periodic flow of water and particles through the pores but yielding a net motion of the particles without moving the liquid itself.
