Abstract
Nanomaterials are tailored particles designed to have very small dimensions to gain the advantages of unique physicochemical properties existing in the nanoscale. Nanomaterials have grasped much research attention owing to their important prospects in many applications such as drug delivery, nucleic acid detection, electrochemical/optical sensors/biosensors, and pharmaceutical industries. Due to their very small size, nanomaterials demonstrate unpredictable behaviors and amazing properties such as high surface-area-to-volume ratio and enhanced electronic, electrical, magnetic, and mechanical properties. In addition, the solubility and optical properties of most of the nanomaterials differ significantly from those of bulk materials due to their reduced size. Nanomaterials were found to easily penetrate the human skin and pass through the blood–brain barrier, thus exerting negative health effects in some cases. This chapter gives an overview of nanotechnology, the different types of nanomaterials, their composition, and recent advances in their synthesis. At the end of this chapter, the reader can find a hint about the most common techniques used to characterize nanomaterials.
