Nanoprecipitation of miglyol into droplets surrounded by a functional glycopolymer generates nanocapsules of biointerest. Fluorophores are trapped in situ or post-grafted onto the crosslinked polymer shell for efficient imaging. The resulting colloids induce aggregation of bacteria through strong specific interactions and promote their facile removal.

Nanoparticles (NPs) of donor–acceptor organic semiconductors are produced by a one-step nanoprecipitation with Janus morphology. Electron donor P3HT was blended electron acceptor PC61BM in tetrahydrofuran and then precipitated water, first surfactant second without surfactant. Cryogenic transmission microscopy reveals an internal structure at high magnification, for NPs which have, the past, be...
