Insertion of nanoparticle clusters into vesicle bilayers.

A major contemporary concern in developing effective liposome-nanoparticle hybrids is the present inclusion size limitation of nanoparticles between vesicle bilayers, which is considered to be around 6.5 nm in diameter. In this article, we present experimental observations backed by theoretical considerations which show that greater structures can be incorporated within vesicle membranes by promoting the clustering of nanoparticles before liposome formation.
