Green nanotechnology is a thrilling and rising place of technology and generation that braces the ideas of inexperienced chemistry with ability advantages for sustainability, protection, and the general protection from the race human. The inexperienced chemistry method introduces a proper technique for the production, processing, and alertness of much less dangerous chemical substances to lessen threats to human fitness and the environment. The technique calls for in- intensity expertise of the uncooked materials, particularly in phrases in their creation into nanomaterials and the resultant bioactivities that pose very few dangerous outcomes for people and the environment. In the twenty-first century, nanotechnology has become a systematic breakthrough. Metallic nanoparticles (steel or steel oxide nanoparticles) have attracted loads of hobbies because of their different physiological, technological, and chemical The biological technique is popular because it produces green nanoparticles in an environmentally friendly, simple, easy, quick, and cost-effective manner. Amino acid phenolic, flavonoids, terpenoids, and proteins are examples of reduced and oxidizing agents. Agents of stabilization, synthesis using plants, on the other hand, was already being debated., basics of green synthesis techniques explored in this study with an emphasis on metals or metal oxides (ZnO, AgO, and TiO2),terpenoids as well as proteins, which can operate as chemical reducing and oxidizing agents, as well as stabilization and of agents. Green synthesis using plants, , is still being debated.
