Photoactive chelating organic nanospheres as central platforms of bimodal hybrid nanoparticles

An innovative approach based on the combination of pre-formed nano-objects using photoactive chelating organic nano-platforms has been developed to elaborate hybrid functional nanoparticles. In this way, original “raspberry-like” structures made of a self-assembled fluorescent organic core surrounded by magnetic nanoparticles have been obtained. The resulting fluo@mag architecture exhibits strong brilliance and magnetization compared to the usual structures made of an inorganic core. The reported fabrication procedure represents a simple and very general method which can be applied to any couple of units displaying complementary complexing abilities to yield dense magneto- and photoactive nanomaterials whose core emission appears advantageously insensitive to the surroundings.
