An advanced and eco-friendly method for development of nanoparticles is the fundamental role of Nanotechnology. In recent times, the domain of nanotechnology and nanoscience research has witnessed remarkable advancement, resulting in its colloquial name “tiny science.” The convergence of nanotechnology and biology leads to the emergence of a highly sophisticated domain known as nanobiotechnology. Nanoparticles are considered the primary structural units in nanotechnology. These particles, referred to as NPs, are typically sized between 1 and 100 nm and are composed of carbon, metal, metal oxides, or organic compounds. The biogenic synthesis of nanoparticles (NPs) exhibits a range of favourable attributes, including cost-effectiveness, minimal environmental hazards, and a biological reduction process. As a result, it has emerged as an appealing alternative to chemical methods. Utilization of bacteria, fungi, algae, yeast, and plants characterizes the green approach. These green methods have been found to be safe as compared to the physical and chemical methods. The biosynthesized metallic nanoparticles have an unlimited range of biomedical applications. Their use has been increasing day by day in a variety of processes such as drug delivery, biosensors, gene delivery, wastewater treatment and many more. Access to clean and safe water is essential for the holistic development of society and a prosperous economy. Rapid population growth, increased industrialization, urbanization, and intensive agricultural activities have led to the production of wastewater, which has not only contaminated water sources but also made them hazardous. Countless individuals lose their lives annually as a result of illnesses transmitted by consuming water tainted with harmful pathogens. Nanoparticles exhibit a substantial surface to volume ratio, exceptional sensitivity and reactivity, a remarkable adsorption capacity, and ease of functionalization, making them well-suited for utilization in wastewater treatment. This paper presents a comprehensive study on the green synthesis of Zinc oxide nanoparticles utilizing leaf extracts obtained from Azadirachta indica. The NPs’ structural and optical properties were thoroughly investigated using UV-Visible spectroscopy [UV-Vis] and Fourier Transform-Infrared Spectroscopy [FT-IR]. The antibacterial efficacy of ZnO NPs was evaluated using the paper disc diffusion method against coli formic bacteria. The results revealed that ZnO NPs synthesized with the aid of Azadirachta indica exhibited potent antimicrobial activity against pathogens. These findings suggest that the plant-based synthesis of NPs can serve as an excellent strategy for the development of versatile and eco-friendly bio medicinal products.
