Antimicrobial fabrics have gained considerable interest for use in different fields of application. However, most of these antimicrobials have many disadvantages viz., toxicity on non-targets, environment, and low durability of finished products, etc. The study aimed to develop an eco-friendly nanoparticle that can be used both as an antimicrobial and coloring agent. Fungi are known to produce a wide spectrum of colors as secondary metabolites, and they are also capable of creating nanoparticles. Thermomyces sp. is capable of producing a yellow pigment along with the ability to synthesize silver nanoparticles. UV-Vis spectroscopy, FT-IR, and TEM were used to analyze the synthesized silver nanoparticles. The size of the silver nanoparticles was found to be between 10 and 50 nm, and nanoparticles treated cloth displayed 90% antibacterial action against Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa.
