Controlled release

Multi-arm star poly(ethylene glycol) (PEG) polymers have a number of advantages over linear PEG polymers when used as carriers for drug delivery and controlled release. For instance, they have more terminals that can be modified to form multi-functional delivery systems with significantly…

We present the design of a novel pH-responsive drug release system that is achieved by solventless encapsulation of drugs within a microporous membrane using a thin capping layer of biodegradable polymethacrylic anhydride (PMAH) coating. The coating was synthesized via a mild vapor polymerization…

In recent years there has been a growing interest in solid lipid-based systems, particularly in solid lipid microparticles (SLMs); however, only very few studies deeply investigated the dissolution behaviour of orally delivered-SLMs. The present study provides new insights about the release…
