Abstract
In the recent past, the nanobiotechnology field has grown up tremendously with more applications because the synthesis process will be more practically possible techniques. Since, plant-derived biosynthesis of silver nanoparticles is superior since its eco-friendly, cost-efficient, speedy process in nature. Alginate-based eco-friendly, biodegradable nanocomposite films were prepared with Celosia cristata leaf extracts silver nanoparticles (CC-AgNPs) and sodium alginate by simple casting techniques. The synthesized alginate-silver (Alg-Ag) nanocomposite films were characterized and confirmed by UV/Vis spectroscopy, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), thermogravimetric analysis (TGA) and atomic force microscopy (AFM). The various characterization process was further confirmed synthesized CC-AgNPs and Alg-Ag nanocomposite films. In addition, TEM and SEM monogram also showed uniformity and smooth surface of Alg-Ag nanocomposite films. The nanocomposite films displayed effective antimicrobial proficiency against selected foodborne pathogens i.e., Staphylococcus aureus, Salmonella typhimurium and Clostridium perfringens. Further, the Alg-Ag nanocomposite films resolve and eliminate the microbial intruders and enhance food stuff's quality and storage stability.
