Ukusebenza

I-PLGA ipholishwa zii-monomers ezimbini, i-lactic acid kunye ne-glycolic acid, kwaye iintlobo ezahlukeneyo ze-PLGA zinokulungiswa ngemilinganiselo eyahlukeneyo. Zii-polymer organic compounds ezinokubola kwaye zisebenza kakuhle, zithambile kwaye ziyanwebeka, kwaye zinokuhambelana kakuhle kwezinto eziphilayo. Zisetyenziswa kakhulu kwi-suture yotyando, i-anti-adhesion membrane, i-tissue engineering scaffold kunye nezinye izixhobo zonyango. Umgangatho wokonakala kwe-PLGA uyahluka ngokwe-monomer ratio. Ngokubanzi, okukhona umlinganiselo we-glycolide umkhulu, kokukhona ibola lula.
