Composite alginate and gelatin based bio-polymeric wafers containing silver sulfadiazine for wound healing

Lyophilized wafers comprising sodium alginate (SA) and gelatin (GE) (0/100, 75/25, 50/50, 25/75, 0/100 SA/GE, respectively) with silver sulfadiazine (SSD, 0.1% w/w) have been developed for potential application on infected chronic wounds. Polymer-drug interactions and physical form were characterized by Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD), respectively, while morphological structure was examined using...
