PLGA Poly (D, L-lactide-co-glycolide) CAS 26780-50-7
Khoom npe: Poly (D, L-lactide-co-glycolide)
Synonyms: PLGA; PDLGA; poly (lactic-co-glycolic) Acid
CAS: 26780-50-7 Nr
Cov mis mos molecular: (C6H8O4)n(C4H4O4)m
PLGA yog polymerized los ntawm ob monomers, lactic acid thiab glycolic acid, thiab ntau hom PLGA tuaj yeem npaj tau ntawm qhov sib txawv. Lawv yog biodegradable thiab haumxeeb polymer organic compounds, mos thiab elastic, thiab muaj biocompatibility zoo. Lawv tau siv dav hauv kev phais suture, anti-adhesion membrane, cov ntaub so ntswg engineering scaffold thiab lwm yam ntaub ntawv kho mob. Lub degree ntawm PLGA degradation txawv nrog monomer piv. Feem ntau hais lus, qhov ntau dua qhov feem ntawm glycolide, nws yooj yim degrades.
