Molecular catch and release: controlled delivery using optical trapping with light-responsive liposomes.

ABSTRACT: Gold-coated liposomes are maneuvered using an optical trap to achieve precise delivery of encapsulated molecular cargo. Movement and payload release from these plasmon resonant nanocapsules are independently controlled using a pulsed trapping beam. This technology enables in vitro delivery of a payload to a selected cell and may be applied to the interrogation of individual cells within their biological microenvironment.
