Nanomaterials are quickly becoming recognised as the most potent substance in the universe. Due to the fact that it has a strong foundation in the "Nanotechnology". Aerogel, fullerene, and carbon nanotube are three distinct nano materials that are discussed in detail here, and their applications range from tissue engineering and cancer medicines to sports equipment and lithium-ion batteries to solar panels. The impact of nano materials on human existence is greatly expanding daily. People should therefore be aware of the significance of nanotechnology and nano materials. The content covered in the current study spans "Green nanotechnology" to the beginnings of nanotechnology. Additionally, it examines contemporary developments in nanotechnology. The general information about nanotechnology and nano materials is well-equipped, allowing people to understand the topic with ease.
