Nanoparticles have gained significant attention due to their unique properties and various applications in fields such as electronics, medicine, and catalysis. However, traditional nanoparticle synthesis methods often involve the use of harmful chemicals and energy-intensive processes, leading to environmental pollution and high production costs. Therefore, there is a growing need for the development of efficient and sustainable green methods for nanoparticle synthesis. This abstract focuses on an innovative green method for nanoparticle synthesis that utilizes environmentally friendly materials and reduces energy consumption. The method involves the use of plant extracts or bio-waste products as reducing agents and stabilizers to facilitate the synthesis of nanoparticles. The plant extracts or bio-waste products are rich in phytochemicals or biomolecules that can efficiently bind to metal ions and reduce them to form nanoparticles. These phytochemicals act as natural reducing agents and possess unique properties that control the size, shape, and stability of the nanoparticles.
