According to the standard definition of nanoscale materials with a unit size of 1–100 nm are considered to be nanomaterials. Utilizing developments in materials metrology and synthesis created in support of microfabrication research, nanomaterials research approaches nanotechnology from the perspective of materials science. Nanoscale materials frequently exhibit special optical, electrical, thermophysical, or mechanical capabilities. Nanomaterials are gradually being put on the market and turning become commodities. Paints, filters, insulation, and lubricant additives are just a few of the goods, manufacturing processes, and healthcare applications that employ nanomaterials. Nanozymes, which resemble enzymes, are nanomaterials used in the medical field. They are a new kind of artificial enzyme that have a variety of uses, including biosensing and others.
