Preparation of Silver Sulfadiazine Loaded Pectin-Zinc Nanocomposites for Improvement of Antioxidant, Antibacterial and Care Cutaneous Wound Care During the Perioperative Period

Abstract

Medicinal care for cutaneous wound becomes difficult due to the emergence of antibiotic resistant bacteria. The development of a new cost-effective drug based on silver sulfadiazine loaded with pectin-zinc nanocomposites offers better therapeutics in wound healing besides its role in enhancing antioxidant and antibacterial activities. In this study, silver sulfadiazine loaded with pectin-zinc nanocomposites (AgSD-PC-Zn) was produced and its antioxidant and antimicrobial properties were tested against wound infection causing bacterial pathogens (S. aureus and E. coli). The synthesized AgSD-PC-Zn composite was biophysically characterized. TEM analysis confirmed the spherical shape of NPs. AgSD-PC-Zn composite exhibited a greater antibacterial effect against S. aureus and E. coli. The number of dead bacterial cells was higher after exposure to AgSD-PC-Zn composite. Furthermore, in vitro antioxidant enzyme activities (DPPH and H2O2) were increased with AgSDPC-Zn composite. A rapid healing of the skin wounds in mouse was noticed with AgSD-PC-Zn composite treatment. This study concludes that the newly formed AgSD-PC-Zn composite will act as a strong antimicrobial and antioxidant agents for treating skin wound infection.
