Abstract
This research focused on the development of an antimicrobial polymeric composite coating of polyethylene glycol (PEG) infused with zinc oxide nanoparticles (ZnO) and herbal extracts from Curcuma longa (turmeric). The synthesized composite is coated on a biodegradable vicryl suture via the dip coating method. Instrumental characterization, including Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM), was utilized to confirm the chemical composition and surface of the coated suture. The antimicrobial activity was evaluated against bacterial pathogens, Gram-positive (Staphylococcus aureus and Enterococcus faecalis) and Gram-negative (Escherichia coli and Pseudomonas aeruginosa). The water contact angle was measured to determine surface wettability. Degradation studies were conducted in simulated intestinal fluid (SIF) to determine the coated suture’s longevity.
