The texture and size of manufactured nanoparticles are influenced by the pH of solution media. Due to its wide applications in electronics, coatings, optical materials, and catalysis the alloy nanomaterials are of tremendous interest now days. Turkevich approach is a viable technique for chemical production of GNPs. Nanoparticles of certain materials can be made via "wet chemical methods", in which appropriate compound solutions are combined to make an insoluble compound of the desired substance. Nanowires created through lithography, for example, are not always smooth and can have a lot of impurities and structural flaws on their surface. The Polyol technique is a chemical approach for nanoparticle production. Non-aqueous liquid (polyol) is used as a reducing agent and solvent in this process. A colloidal solution of particles suspended in a liquid phase is known as a sol. The biological production of MNPs has always been advantageous. The reverse micelle approach can also be used to create nanoparticles with specific size and shapes. Chemical precursors are typically a combination of chlorides, metals and oxides that react during milling or heat treatment to generate a composites powder with ultrafine particles scattered in a stable salt matrix.
