Description

Application

Thiol poly(ethylene glycol)-block-poly(lactide-co-glycolide) is a thiol-functionalized, biocompatible, amphiphilic block copolymer. Due to its self-assembling properties, this material can be used in the formation of nanoparticles for drug delivery. Additionally, due to the thiol-functionalization of the PEG block, this material can be used to rapidly covalently conjugate biomolecules, API, or targeting ligands. Potential uses include the targeted and/or controlled release of cancer drugs, anti-inflammatory drugs, antibiotics, or anaesthetic agents.
