General description

Block copolymer micelles are widely used in drug delivery applications. PEG-PDLLA is a biodegradable polymeric micelle which is used as a carrier for hydrophobic drugs like Paclitaxel. The hydrophilic PEG and hydrophobic PDLLA form the micelle core wherein the hydrophobic drug is loaded. The incorporation of the 10-alkyl end cap (decane) increases the hydrophobicity of the micelle core and increases its solubilizing capability for hydrophobic drugs.†

Application

Used as a carrier for the controlled and targeted release of anticancer hydrophobic drugs.

Features and Benefits

  • Good biocompatibility, low immunogenicity and good degradability.
  • Properties can be easily modulated by changing the block copolymer segment sizes to suit a particular application.

It is generally assumed that polymeric micelles, upon administration into the blood stream, carry drug molecules until they are taken up into cells followed by intracellular release. The current work revisits this conventional wisdom. The study using dual-labeled micelles containing

This work describes the synthesis and characterization of novel thermoresponsive highly branched polyamidoamine-polyethylene glycol-poly(D,L-lactide) (PAMAM-PEG-PDLLA) core-shell nanoparticles. A series of dendritic PEG-PDLLA nanoparticles were synthesized through conjugation of PEG of various chain lengths (1500, 6000 and 12,000 g mol(-1)) to
