PEGylated Polyamino Acids

PEGylated polyamino acids are materials that have attracted much attention in the field of drug delivery. Its unique structure gives drug molecules a more stable carrier and prolongs the circulation time of drugs in the body. The introduction of polyethylene glycol (PEG) not only improves the water solubility of polyamino acids, but also gives it excellent biocompatibility and slows down recognition by the immune system. The application of this material in drug delivery can effectively improve the bioavailability of drugs and reduce side effects.

Due to the tunable structure of polyamino acids, PEGylated polyamino acids can achieve precise control of the drug release rate by adjusting the length and structure of the molecular chain. This provides more options for customization of drug delivery systems. In addition, the presence of PEG also gives polyamino acids unique targeting properties, allowing them to deliver drugs to specific tissues or cells in the body to improve therapeutic effects.

In general, PEGylated polyamino acids, as important materials in the field of drug delivery, have good biocompatibility, stability and controllability, providing broad prospects for the design and application of drug delivery systems.
