title: Glycopolypeptide-encapsulated Mn-doped ZnS quantum dots for drug delivery: fabrication, characterization, and in vitro assessment.
abstract: In this work, glycopolypeptide nanoparticles (GPNPs) composed of Mn doped ZnS quantum dots (QDs) as core and glycopolypeptides as shell were synthesized through the surface initiated polymerization of N-carboxyanhydrides and surface condensation polymerization with carboxymethyldextran on amine-functionalized QDs. The loading and release behavior of ibuprofen on the GPNPs were investigated. The GPNPs exhibited not only high loading but also controlled release behavior. The cytotoxicity of the GPNPs was evaluated by incubating with HEK293T cell lines and they were shown to be of low cytotoxicity. They appear to be a very promising candidate for targeted drug delivery.
