Green synthesized metal silver nano particles for fabric coating and its applications

Abstract

The safest and the most environmental friendly processes for synthesizing nanoparticles is green synthesis. Plant sources can be used as reducing agents in place of hazardous chemicals and thus prevents causing environmental toxicity. Silver NPs takes the most fascinating position because of its unique antimicrobial properties. The bark extract of Barringtonia acutangula was used in the current study to biosynthesize silver nanoparticles (AgNPs), which were then coated on pure cotton fabric using the dip coat method. Initially, the synthesised AgNPs was visualised by change in colour. Additionally, FT-IR, UV–Visible spectroscopy, SEM, and TEM were used to study the morphology of the nanoparticles, their average size, and the presence of elemental silver. XRD results confirmed that the green synthesized AgNPs have an average particle size and are face-centered cubic crystalline in nature. In vitro antimicrobial effect of AgNPs coated cotton cloth was tested against both Gram-positive and Gram-negative bacterial strains. The findings demonstrate that biosynthesized AgNPs have potent antibacterial properties. It was proven that the bactericidal effect was very effective. The coated fabric has potential uses as a bed liner, a wound dressing, and as medical bandages. The coated fabric is also suggested for cleaning domestic spaces and for sanitizing food- and medical-related equipment. Furthermore,The ingredients used in the preparation are also affordable, non-toxic, and widely accessible..
