Abstract:

A novel amphiphilic copolymer based on dextran, poly(lactide) (PLA) and 1.2-dipalmitoyl-sn-glycero-3-phosphoethanolamine (DPPE) was synthesized and characterized by FT-IR, H-1 NMR, C-13 NMR and P-31 NMR spectra. Their molecular weights were determined by gel permeation chromatography (GPC). The molecular weights range from 30 000 g mol(-1) to 37 000g mol(-1) with a feed weight ratio of 20:1-50:1 (DPPE/activated dextran-PLA). Its micellar characteristics were investigated using fluorescence technique, transmission electron microscopy (TEM) and dynamic light scattering (DLS). It was found that dextran-PLA-DPPE copolymer could form spherical micelles. The micelle diameters ranged from 85 to 120 nm with a feed weight ratio of 20:1-50:1 (DPPE/activated dextran-PLA) in the absence of surfactant. (C) 2010 Elsevier Ltd. All rights reserved.
