Three-Dimensional Lock and Key Colloids

ORAL

Abstract

Colloids based upon silica patchy particles featuring a (trimethoxysilyl)propyl methacrylate matrix are synthesized. Selective etching of the silica patches results in the controllable fabrication of colloids with three-dimensional multicavities. The obtained hollow particles exhibit depletion interaction-driven self-assembly with polystyrene spheres in the presence of poly(ethylene oxide), demonstrating for the first time three-dimensional lock and key colloids.
