Clicking Well-Defined Biodegradable Nanoparticles and Nanocapsules by UV-Induced Thiol-Ene Cross-Linking in Transparent Miniemulsions

A novel approach for the preparation of nanomaterials is developed by tuning miniemulsion reaction systems to be transparent in order to enable highly efficient photoreactions. Biodegradable nanoparticles and nanocapsules are obtained by UV-induced thiol-ene cross-linking of polylactide (PLA)-based precursor polymers preassembled in transparent miniemulsions. These well-defined nanomaterials may potentially serve as ideal scaffolds for drug delivery.
