ABSTRACT
The initial idea of nanotechnology was proposed in 1959 by Richard Feynman while the exact term “nanotechnology” was used by Norio Taniguchi in 1974. Feynman discussed this idea during his lecture entitled: “There’s Plenty of Room at the Bottom” [1]. When the dimensions of the solid materials become very small, they present different physical and chemical properties compared to those of the same material in larger size [2]. Based on definition, a product is considered a nanomaterial if at least one of its dimensions falls within the 1–100 nm range. Nanomaterials are typically metals, ceramics, polymers, organic materials, or composites [3]. The novel properties of nanomaterials could be due to their extremely large surface area and the high surface-to-volume ratio of these compounds compared to similar conventional materials [4]. Nanomaterials include but are not limited to nanoparticles, nanocomposites, nanocrystals, nanoclusters, nanofibers, nanotubes, nanofilms, nanowires, and nanorods. There has been tremendous progress in the field of nanotechnology in recent decades [1]. Nanotechnology is growing fast because nanomaterials are well incorporated into many aspects of our lives [5].
