PLGA yog polymerized los ntawm ob lub monomers, lactic acid thiab glycolic acid, thiab ntau hom PLGA tuaj yeem npaj tau ntawm ntau qhov sib piv. Lawv yog cov biodegradable thiab ua haujlwm polymer organic compounds, mos thiab elastic, thiab muaj biocompatibility zoo. Lawv siv dav hauv kev phais suture, anti-adhesion membrane, tissue engineering scaffold thiab lwm yam khoom siv kho mob. Qib ntawm PLGA degradation sib txawv nrog monomer piv. Feem ntau hais lus, qhov ntau dua ntawm glycolide, qhov yooj yim dua nws degrades.
