摘要

The present study included the biosynthesis and characterization of silver nanoparticles (AgNPs) for their excellent role as an antibacterial agent using Candida albicans. The total of two clinical isolates of C. albicans (Ca-2 and Ca-4) have been reidentified by conventional yeast recognition techniques. By mixing the cell-free culture filtrate with silver nitrate, a change in color from light yellow to brownish was observed, signifying the formation of AgNPs. The ultraviolet and visible (UV–Vis) spectroscopy confirmed the biosynthesis of AgNPs with the highest absorption wavelengths at 425 nm (Ca-2) and 435 nm (Ca-4). The X-ray diffraction (XRD) technique exhibited a polycrystalline nature of 23.40 nm (Ca-2) and 33.70 nm (Ca-4). The energy dispersive X-ray (EDX) spectroscopy provided the weight fraction of silver contents at 50.90% (Ca-2) and 58.50% (Ca-4). The scanning electron microscopy (SEM) showed that the AgNPs were polydispersed, spherical, and disaggregated, with average sizes of 108.45 nm (Ca-2) and 117.51 nm (Ca-4). The valuable antibacterial activity of the biosynthesized AgNPs was determined against Gram-positive and Gram-negative pathogens. Hence, significant antimicrobial activity might flourish AgNPs as a novel antimicrobial agent to cure multidrug-resistant bacterial infections.
