일반 설명

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.

애플리케이션

Used in the synthesis of targeted nanoparticles which are used for differential delivery and controlled release of drugs.
forming "stealth" pegylated microparticles

특징 및 장점

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

Solubility enhancement of hydrophobic drugs via drug-loaded micelles using biodegradable PEG- polyester diblock copolymers

One of the common difficulties with intravenous drug delivery is low solubility of the drug. The requirement for large quantities of saline to dissolve such materials limits their clinical use, and one solution for this problem that has recently generated interest is the formation of drug-loaded micelles.

Electrospun Nanofibers for Drug Delivery Systems

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.

Fabrication of Drug-loaded Microparticles Using Hydrogel Technology and Recent Innovation in Automation

Microparticle drug delivery systems have been extensively researched and applied to a wide variety of pharmaceutical and medical applications due to a number of advantages including injectability, local applicability to target tissues and sites, and controlled drug delivery over a given time period.

Biodegradable Polyester-based Nanoparticle Formation by Miniemulsion Technique

Aliphatic polyesters such as polylactide, poly(lactide-co-glycolide) and polycaprolactone, as well as their copolymers, represent a diverse family of synthetic biodegradable polymers that have been widely explored for medical uses and are commercially available.
