Polymers for controlled drug delivery
WebInspired by the specific properties in TME, we designed and prepared dual pH and redox-responsive hybrid lipid-polymer nanoparticles (LPNPs) for anticancer drug delivery and controlled release in the present work. The LPNPs were fabricated with the PEGylated lipid (DSPE-mPEG) and amphiphilic copolymer poly (ethylene glycol) methyl ether-grafted ... WebTargeting delivery of drugs to the diseased lesions is one of the most important aspects of DDS. To convey a sufficient dose of drug to the lesion, suitable carriers of drugs are needed. Polymers, which swell and contract in response to external pH levels, are being explored. The research in this area is being carried out all over the world at ...
