MPEG-PCL

Price range: $260.00 through $960.00

mPEG-PCL (Methoxy Polyethylene Glycol-b-Polycaprolactone) is a tin-free, biodegradable amphiphilic block copolymer composed of methoxy polyethylene glycol (mPEG) and polycaprolactone (PCL). The hydrophobic PCL segment enables efficient encapsulation of hydrophobic drugs, while the hydrophilic PEG segment improves aqueous solubility, colloidal stability, and biocompatibility. mPEG-PCL is widely used for polymeric micelles, nanoparticle fabrication, drug delivery, and biomedical research applications.

Description

General Description

mPEG-PCL is a biodegradable diblock copolymer extensively utilized in nanomedicine and controlled drug delivery systems. Due to its amphiphilic nature, mPEG-PCL self-assembles in aqueous environments to form polymeric micelles and nanoparticles with a hydrophobic PCL core and a hydrophilic PEG shell.

The PCL block exhibits excellent biocompatibility and slow biodegradation characteristics, making mPEG-PCL particularly suitable for sustained drug release applications. The PEG corona reduces protein adsorption, improves colloidal stability, and prolongs circulation time. mPEG-PCL has been widely investigated for the delivery of anticancer drugs, proteins, peptides, and imaging agents.
