Descrizione generale

Block copolymer micelles are widely used in drug delivery applications. PEG-PDLLA is a biodegradable polymeric micelle which is used as carriers for hydrophobic drugs like paclitaxel. PEG is the hydrophilic part and PDLLA is the hydrophobic part which forms the micelle core wherein the hydrophobic drug is loaded.

Applicazioni

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

Caratteristiche e vantaggi

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

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

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
