Controllably layer-by-layer self-assembled polyelectrolytes/nanoparticle blend hollow capsules and their unique properties: Polymer/nanoparticle composite capsules with controllable incorporation of nanoparticles were fabricated by Layer-by-Layer blend self-assembly. The team from Singapore claim this offers a universal approach to fabricate well-dispersed microcapsules with controllable incorporation of nanoparticles for various applications such as intelligent drug delivery, biosensing, and bioimaging.
