ABSTRACT
Nanotechnology is the knowledge and control of matter at dimensions of roughly 1-100 nm, where unique phenomena enable novel applications. Encompassing nanoscale science, engineering, and technology, nanotechnology involves imaging, measuring, modeling, and manipulating matter at this scale (National Nanotechnology Initiative, 2006). Nanotechnology is a fundamental high-tech technique and is regarded as one of the key technologies of the twenty- rst century. This technology holds major potential to generate new products with numerous bene ts. The principle of nanotechnology is that materials with known properties and functions at their normal size will display different and often useful properties and functions at their nanosize. Thus, scientists manipulate objects of 1-100 nm in order to fabricate and identify materials and structures with novel properties and functions (Lagaron et al., 2005; Weiss et al., 2006). Nanotechnology has opened up new possibilities in various elds, including medicine, cosmetics, agriculture, and food, and has already been
