Abstract:
It is commonly believed that small sizes do not matter, but in the field of nanotechnology, the smallest size of matter is all that matters. Nanotechnology refers to a set of techniques used to manipulate,1 image, measure, and model matter at dimensions [roughly] between 1 and 100 nano-meters. 2 These dimensions are otherwise known as nano-scale.3 At this length scale, the physical, chemical and biological properties of matter such as conductivity, magnetism, elasticity, reactivity, quantum mechanics, melting temperature and colour may change in unusual and unexpected ways.4
