Abstract

The formation of nanostructures in the first meteorites marks the beginning of the history of nanomaterials, which dates back to the big bang. Later, many more nanostructures like skeletons and seashells appeared in nature. Nanoscale smoke materials were created by early humans using fire. The scientific history of nanomaterials, however, started considerably later. The colloidal gold nanoparticles created by Michael Faraday in 1857 are among the earliest scientific publications. Precipitated and fumed silica nanoparticles were being produced and offered as an alternative to ultrafine carbon black for rubber reinforcements in the USA and Germany by the early 1940s. Despite the fact that nanomaterials have a lengthy history, significant advances in nanoscience have just recently emerged. Researchers from various academic disciplines, including biology, medicine, chemistry, mechanics, and materials science, collaborate on research on nanoparticles. The utilisation of nanomaterials causes a significant change in the fields of biotechnology and medical science. Initial test results demonstrate the viability of using nanomaterials for a variety of drug delivery systems, cancer tumour therapy, or cancer tumour detection. Such materials demonstrated a significant impact on the resolution of numerous healthrelated issues. There is a lot of nanotechnology-based research being done to assist patients with HIV and diabetes.
