Indium Nanoparticles, Atomic number 49, is listed as Block P with period 5. In the process of Zinc production, it is gained as the by-product. Mostly, it is available in the form of black powder. Direct touch with the present element, particularly in the form of black powder, may be dangerous. A simple hot injection method and laser ablation techniques emerge as the fine method to get the indium Nanoparticles. It is widely used in the semiconductor industry. Indium Nanoparticle is also used to make LCD panels. In the welding process, the need is felt to low the melting point of the alloy; that’s why it is necessarily used in the welding alloy. To improve the combustion capability of the rocket fuel, indium is used extensively. The solar industry is another field in which indium Nanoparticles are used to create solar cells. Researchers are trying to explore the benefit of this material in the biomedical, optical, and bioscience fields.
