Silicon, atomic number 14, is listed as the symbol Si. Silicon nanoparticles have a large surfacing area. It is a great component of luminescent display devices. As nickel and platinum nanoparticles great role in the solar energy field, silicon nanoparticles are also being used in solar energy. Being used as the delivery agents of nucleotides and proteins and other chemicals, Silicon nanoparticles are playing a great role in the field of agriculture fields. To regulate the metabolic activities, the silicon nanoparticles are being used successfully. In the agricultural field, the use of silicon nanoparticles as the nanocarrier of necessary elements is second to none. It plays a constructive role in the development of the agricultural field. The use of silicon nanoparticles in the production of Lithium-ion batteries is another best role played by the silicon nanoparticles. Two methods can be used to gain the silicon nanoparticles. The first is pulsed laser ablation of silicon and the second hydrolysis of alkyl silicates.
