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.

Polymeric nanoparticles (PNPs) may efficiently deliver in vivo therapeutics to tumors when conjugated to specific targeting agents. Gint4.T aptamer specifically recognizes platelet-derived growth factor receptor β and can cross the blood-brain barrier (BBB). We synthesized Gint4.T-conjugated PNPs able of high

Poly (lactic-co-glycolic acid) (PLGA) copolymers have been broadly used in controlled drug release applications. Because these polymers are biodegradable, they provide an attractive option for drug delivery vehicles. There are a variety of material, processing, and physiological factors that impact
