On-chip dielectrophoretic coassembly of live cells and particles into responsive biomaterials.

Abstract

We report how live cells and functionalized colloidal particles can be coassembled into a variety of freely suspended bioactive structures using dielectrophoresis on a chip. Alternating electric fields were applied to dilute suspensions of yeast (S. cerevisiae) and NIH/3T3 mouse fibroblast cells to yield 1D chains and 2D arrays. The effects of voltage… (More)
