PCL/PEG Copolymeric Nanoparticles: Potential Nanoplatforms for Anticancer Agent Delivery

Nanotechnology provides researchers with new tools for cancer treatment. Biodegradable polymeric nanoparticles, as an advanced drug delivery system, have promising applications in cancer treatment. Poly(ε- caprolactone)/poly(ethylene glycol) (PCL/PEG) copolymers are biodegradable and amphiphilic, and show potential application in drug delivery. In recent years, PCL/PEG copolymeric nanoparticles, as a potential nanoplatform for anticancer agent delivery, received increasing attention. This paper reviews PCL/PEG copolymer nanoparticles for anticancer agent delivery, including overcoming water insolubility of hydrophobic drug, targeting chemotherapeutic drug to tumor, and delivering genes, vaccines, and diagnostic agents.
