Nanoparticles are currently a subject of intense research owing to their potential applications in electronic, optical and biomedical fields. Nanoparticles have unexpected optical properties owing to their small size and are capable of producing quantum effects.
Manganese is found in several minerals and as a free element in nature. It is hard and brittle, and tarnishes slowly in air and rusts in water containing dissolved oxygen. It is mainly used as industrial metal alloy, particularly in stainless steels.

Manufacturing Process
Manganese nanoparticles can be produced by several methods. They can be synthesized using the inert gas condensation method where manganese is evaporated in an inert gas environment, and the vapor is allowed to cool by the surrounding inert gas atoms. This results in the formation of manganese nanoparticles, which are then collected and examined through spectroscopy and diffraction techniques.
Manganese nanoparticles can also be produced using n-butyllithium as a reducing agent.
