PLGA-PEG-COOH (Poly(lactide-co-glycolide)-b-Poly(ethylene glycol)-Carboxylic acid) is a functionalized, amphiphilic, diblock copolymer composed of a hydrophilic PEG block and a hydrophobic PLGA block. These biodegradable, biocompatible polymers can self-assemble to form nanoparticles, such as micelles and polymersomes, in both aqueous and non-aqueous media. Due to these properties, these polymers are widely used in polymeric nanoparticle formulation to achieve controlled and targeted delivery of therapeutic agents (e.g. APIs, genetic material, peptides, vaccines, and antibiotics). The carboxylic acid functional group on the PEG chain enables rapid and facile surface functionalization, allowing for these materials to be used in applications such as targeted drug delivery. LA/GA molar ratio will be 1:1 with no request. Specified molecular weight and molecular ratio may be offered by custom synthesis. Please contact us for more details.
