Abstract

This comprehensive review delves into the burgeoning field of nanotechnology, where the synthesis of nanoparticles (NPs) is strategically tailored to specific applications. Embracing the principles of green chemistry, nanotechnology increasingly utilizes environmentally friendly materials, such as plant extracts or microorganisms, as capping or reducing agents and solvents in the synthesis process. Notably, plant-based synthesis demonstrates enhanced stability and faster rates compared to microorganisms. The synthesized materials exhibit unique properties ranging from antimicrobial and catalytic effects to antioxidant activities and they are finding applications across diverse fields. Green synthesis processes, characterized by mild conditions in terms of temperature and reagents, stand in stark contrast to traditional chemical synthesis methods. This review focuses on the synthesis of various metal and metal oxide NPs, including Ag, Au, Zn, Fe, Mg, Ti, Sn, Cu, Cd, Ni, Co, and Ag NPs and their oxides, using plant extracts and microorganisms. We provide a comprehensive analysis of the advantages, disadvantages, and applications associated with each synthesis method. Additionally, we explore the future prospects of green synthesis and its limitations and challenges, offering insights into its evolving role in nanotechnology. Keywords: Microorganisms, green synthesis, plant extract, metal, metal oxide
