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)

"Click" chemistry now offers access to a great variety of triazoles, and the first example of a strategy to stabilize gold nanoparticles (AuNPs) with a new 1,2,3-triazole-mPEG ligand is developed here together with preliminary examples of possible applications.

The effectiveness of systemically administered anticancer treatments is limited by difficulties in achieving therapeutic doses within tumors, a problem that is complicated by dose-limiting side effects to normal tissue. To increase the efficacy and reduce the toxicity of systemically administered
Seung-Young Lee et al.
Biomaterials, 34(2), 552-561 (2012-10-20)
Although targeted delivery mediated by ligand modified or tumor microenvironment sensitive nanocarriers has been extensively pursued for cancer chemotherapy, the efficiency is still limited by premature drug release after systemic administration. Herein we report a highly blood-stable, tumor-adaptable drug carrier
