Green Synthesis of Nanoparticles and their Role in our Everyday Lives: A Review

Nanotechnology is a field of science that works with particles having dimensions of less than 100 nm, mainly the manipulation of individual molecules and atoms, permitting to tailor an extensive range of materials with various traits. In materials science, "green" synthesis has received a great deal of interest as a dependable, sustainable, and environmentally friendly technique for synthesising a wide range of materials/nanoparticles such as metal/metal oxide nanomaterials, hybrid materials, and bioinspired materials. As a result, green synthesis is recognised as a significant technique for reducing the harmful consequences associated with standard methods of synthesis for nanoparticles routinely used in laboratories and industry.

The field of nanotechnology has grown in importance in recent years, with a wide range of applications predicted in many disciplines of Science and Technology, with a significant influence on our everyday life. Nano-based chemicals have found a place in the market as consumer items such as paints, construction materials, cosmetics, medical treatment, the food sector, and so much more as a new development strategy. More helpful products, better treatments for illnesses, and more appropriate building materials can be produced because of nanotechnology. Nanoparticles can be used in a wide range of everyday items, materials, and processes. We detailed the essential processes and mechanisms of "green" synthesis techniques, particularly for metal and metal oxides, in this study. This chapter also explores the most recent nanotechnology applications that have an impact on various aspects of human life.
