Today, nanotechnology (NT) is operating in various fields of science via its operationfor materials and devices using different techniques at nanometer scale. Nanoparticlesare a part of nanomaterials that are defined as a single particles 1–100 nm in diameter.From last few years, nanoparticles have been a common material for the development ofnew cutting-edge applications in communications, energy storage, sensing, data storage,optics, transmission, environmental protection, cosmetics, biology, and medicine due totheir important optical, electrical, and magnetic properties. In particular, the uniqueproperties and utility of nanoparticles also arise from a variety of attributes, includingthe similar size of nanoparticles and biomolecules such as proteins and polynucleicacids.
