ABSTRACT
Nanotechnology has been expanded wide enough and into an interdisciplinary field with outstanding development to replace every traditional scientific discipline. Nanomaterials (NMs) successfully distinguished itself from other materials located within or above the microscale range and are materials with sizes ranging from 1 to 100 nm. They play a remarkable role in both the medical and biological fields because of their uncommon chemical and physical properties. High surface area to volume ratio and extraordinary physicochemical properties like high surface reaction of NMs gained more and more attention from scientists all around the world. This chapter is going to discuss the definitions, properties, toxicities, classification methods of NMs, and instruments that can be used to characterize NMs. Future trends of NMs and some potential applications of NMs in the medical field will be explored and discussed.
