A review on green synthesis of nanoparticles toward sustainable environment

Nanoparticles have become remarkable recognition in a variety of medical fields, including biomedical research, biosensors, pharmaceuticals, catalysis, delivery of drugs, the health sector, beauty products, household products, mechanics, optics, and chemicals due to their outstanding mechanical, chemical, biological, thermal, and physical qualities. The green synthesis method is an environmentally responsible, economical, and safe way to produce nanoparticles (NPs). In contrast, chemical synthesis involves harmful chemicals, and toxic substances that lead to harmful byproducts for the environment. It uses a sustainable strategy that is kind to the environment and encourages resource efficiency, energy conservation, and reduced waste production. For various reasons, green technology-fabricated nanoparticles (NPs) are considerably superior to those fabricated using two distinct techniques physical and chemical processes. Green methods, for instance, produce ecologically friendly substances and byproducts, utilize minimum energy, and do away with the need for expensive chemicals. This review also provides detailed information on the various nanoparticles (NPs) by green method and their various applications in several domains. Furthermore, future areas of research have been highlighted that may be helpful to researchers in investigating novel biogenic synthesis-based green preparation methods. This review explores novel techniques that are economical and safe for the environment. Graphical abstract of green synthesized nanoparticles
