synthesis of poly (vinyl alcohol)-sodium alginate /graphene oxide films for controlled release of the anticancer drug curcumin

Poly(vinyl alcohol) (pva)-sodium alginate (sa)/graphene oxide (go) biocomposite nanofibers have been successfully prepared by casting# the pva-sa nanofibers was composited with 0, 1, 5 and 10 wt% of go# curcumin as drug loaded in nancomposites and the effect of graphene oxide amount on drug release studied# it revealed that the graphene oxide decrease curcumin release rate# ftir analyses showed that graphene oxide was dispersed in polymeric matrix completely and functional groups was intracted with surface of graphene oxide# the results showed that pva-sa/go nanofibers are good candidate for drug delivery system#
