Abstract
nGreen silver nanoparticles (AgNPs) synthesized using medical plant extracts as capping and reducing agents demonstrate broad applicability in addressing the threat posed by infections. In this study, we present a sustainable, low-toxicity, and cost-effective bacterial nanocellulose composite with silver nanoparticles based on green synthesis that uses Origanum vulgare as a reducing agent due to numerous biological components. The formation of AgNPs in composite and morphological properties was analyzed using scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), and transmission electron microscopy (TEM) techniques. Antimicrobial activity was determined using the agar diffusion Kirby–Bauer method against Gram-positive and Gram-negative bacterial strains. The antimicrobial activity of bacterial nanocellulose composite/AgNPs was substantially strong against all tested bacterial cultures. The structural investigation of AgNPs by TEM presents the presence of spherical-shaped silver nanoparticles in cellulose composite. This method of obtaining antimicrobial composites could be widely used to fight against antibiotics, antibiotic-resistant antibiotic-resistant bacteria, and other Gram-positive and Gram-negative bacteria.
