Reconfigurable assemblies of Janus rods in AC electric fields

Soft Matter. 2014 Mar 7;10(9):1320-4. doi: 10.1039/c3sm52418c.

Abstract

We investigate the electric field-induced assembly of Janus colloids composed of silica rods patterned with gold patches in both side- and tip-coated motifs. These shape and chemically anisotropic particles assemble into reconfigurable chains, whose structure depends on patch location, AC electric field strength, and frequency.
