Application

Poly(D,L-lactide-co-glycolide) (PLGA) canbe used:

  • In the formulation ofa non-aqueous drug delivery system for H2S donors to aid thesustained release of the drug.
  • To prepare a polymer blend containing Ganciclovir-loaded microspheresdispersed in PLGA–PEG–PLGA polymer gel. This formulation can be used as asustained delivery system for Ganciclovir drug.
It can also be used to fabricate NO-releasingglucose and lactate sensors.
