Compositions and Uses of Programmable Particles

Abstract

Stimulus-responsive hollow yolk-shell particles (HYSP) comprise: a) at least one orientation-controllable polyphasic yolk containing at least two colorants and at least one stimulus-responsive element, and b) at least one layer of shell encapsulating the orientation-controllable polyphasic yolk. At least a part of the shell contains a material transparent to at least a part of the visible electromagnetic spectrum from about 380 nm to about 800 nm. The orientation-controllable polyphasic yolk is configured to move within the shell in response to an applied force.
