Green Synthesis of Neem-based Zinc Oxide and Titanium Dioxide Nanoparticles for Enhanced Antimicrobial Functionalization of DBD Plasma Treated Silk and Corn Fabrics

Mumal Singh, Mona Vajpayee, Lalita Ledwani and Sudhir Kumar Nema

Abstract

Bacterial infectious diseases pose significant health and socio-economic challenges, necessitating the development of novel antimicrobial agents. Incorporating antimicrobial properties into textile materials is a promising approach, achieved through chemical or physical means. To enhance durability against washing treatments, environmentally friendly plasma surface modification has gained popularity as it selectively targets fabric surfaces without affecting their bulk properties. This research focuses on the green synthesis of zinc oxide (ZnO) and titanium dioxide (TiO2) nanoparticles (NPs) using Azadirachta indica (Neem) leaves extract as a bio-reducing agent. The NPs are characterized using various techniques, including Fourier-transform infrared spectroscopy (FTIR), ultraviolet-visible (UV-Vis) spectroscopy, scanning electron microscopy coupled with energy dispersive X-ray spectroscopy (SEM-EDX), X-ray diffraction (XRD) analysis. The antibacterial efficacy of the synthesized NPs is evaluated against Staphylococcus aureus and Escherichia coli. Furthermore, the NPs are applied to silk and corn fabrics activated by dielectric barrier discharge (DBD) plasma. The antibacterial performance of these fabrics is assessed, highlighting their potential for applications in the fabric industry, particularly in the hygiene product sector.
