Sharaxaada

Darajada caafimaadka PLGA (Poly DL-lactide-co-glycolide)CAS26780-50-7 polymers warshad leh tayada ugu fiican

PLGA waa bakhtiyaanasiib random, polymer amorphous, oo si weyn loogu isticmaalo tolida qalliinka, xuubka-adhesion-ka-hortagga, xoqida injineernimada unugyada.Marka la barbardhigo PLA, wakhtiga xaalufinta polymer waxaa lagu xakameyn karaa iyadoo loo eegayo maadada Ga ee kala duwan, maaddaduna waa mid jilicsan oo jilicsan.Noocyada kala duwan ee PLGA waxaa lagu diyaarin karaa saamiyo monomer oo kala duwan.Tusaale ahaan, PLGA 75:25 waxay tilmaamaysaa in polymer-ku ka kooban yahay 75% lactic acid iyo 25% glycolic acid.Heerka hoos u dhaca PLGA wuu ka duwanaa saamiga monomer kala duwan, iyo marka ay sare u kacdo saamiga ethyl lactide, way fududahay inay hoos u dhigto.
