General description

Amphiphilic block copolymers (AmBC) are made up of two chemically different homopolymer blocks. One of the block is hydrophilic and the other one is hydrophobic. These macromolecules have the properties to self-assemble when dissolved in an aqueous media. PEG-PLGA is one the most commonly used biodegradable amphiphilic block copolymers for drug delivery applications. PEG is the hydrophilic part and PLGA is the hydrophobic part.

Application

Used in the synthesis of targeted nanoparticles which are used for differential delivery and controlled release of 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.

Local delivery of bioactive molecules using an implantable device can decrease the amount of drug dose required as well as non-target site toxicities compared to oral or systemic drug administration.

AliAliphatic polyesters, including polylactide and polyglycolide, are biodegradable polymers widely used in medical applications.

The development of drugs that target specific locations within the human body remains one of the greatest challenges in biomedicine today.
