Synthesis And Application of Partial Block Polymers in Drug Delivery

Abstract

With the rapid development of modern medicine, the application of biodegradable polymers in drug delivery systems has received increasing attention. Due to their good biocompatibility and biodegradability, they can effectively deliver drugs to target sites while avoiding damage to other tissues. As a functional drug carrier, they have brought revolutionary changes to the field of drug development. Biodegradable polymers play a crucial role in drug delivery systems. Many drugs have excellent anti-cancer or other disease treatment effects, but cannot be directly applied in clinical practice due to low absorption rates or toxic side effects. Drug carriers can provide an effective delivery method for these drugs, achieving synergistic effects of multiple drugs and reducing toxic side effects in the human body. This article introduces four polymers, PLA, PEG, PCL, PEO, and the synthesis, modification, and application of three block copolymers of PLA-PEG, PCL-PEG, and PEO-PEG. It also summarizes the new progress of block copolymers in drug delivery and proposes some new issues and prospects for the synthesis of new drug carriers and the construction of drug delivery platforms.
