To promote the application of methoxy poly(ethylene glycol)-cholesterol (mPEG-Chol), mPEG-Chol was used to prepare core-shell micelles encapsulating poorly water-soluble docetaxel (DTX-PM) by modified cosolvent evaporation method. Approaches to enhance DTX entrapment efficiency (EE) and minimize particle size were investigated in

A functionalized poly(amidoamine) (PAMAM) nanocarrier was designed and prepared to deliver anticancer drugs. The nanocarrier is a copolymer with a core-shell structure with 3.0 G PAMAM as the core and sequentially conjugated poly(2-(N,N-diethylamino)ethyl methacrylate) (pDEA) and methoxy-poly(ethylene glycol) 2000 (mPEG)
