The aim of this study is to design a polymeric nanogel system with tailorable degradation behavior. To this end, hydroxyethyl methacrylate-oligoglycolates-derivatized poly(hydroxypropyl methacrylamide) (pHPMAm-Gly-HEMA) and hydroxyethyl methacrylamide-oligoglycolates-derivatized poly(hydroxyethyl methacrylamide) (pHEMAm-Gly-HEMAm) are synthesized and characterized. pHEMAm-Gly-HEMAm shows faster hydrolysis rates of both carbonate and glycolate esters than the same ester groups of pHPMAm-Gly-HEMA. pHEMAm-Gly-HEMAm nanogels have tailorable degradation kinetics from 24 h to more than 4 d by varying their crosslink densities. It is shown that the release of a loaded macromolecular model drug is controlled by degradation of nanogels. The nanogels show similar cytocompatibility as PLGA nanoparticles and are therefore considered to be attractive systems for drug delivery.
