Poly(propylene glycol) (PEG) is a polymer commonly used for drug delivery. Its superior biocompatibility and water solubility make it an ideal drug carrier. PEG can improve the solubility of drugs, prolong the circulation time of drugs in the body, and slow down the metabolism and excretion rate of drugs, thereby improving drug efficacy. In addition, PEG can also reduce drug toxicity to tissues and alleviate adverse reactions during drug delivery. Due to its excellent performance, PEG has been widely used in nano drug carriers, colloidal delivery systems, etc., bringing important breakthroughs and innovations to the field of drug delivery. https://www.cd-bioparticle...
