2.1 NANOTECHNOLOGY: Many main technological innovations in the 21st century is expected to be based on nanotechnology (Mukunthan et al., 2011). It is a rapidly growing multidisciplinary field which includes many branches of science like physics, chemical engineering, super molecular chemistry, mechanical engineering, material sciences, biotechnology and medicine (Dondaa et al., 2013). Bio nanotechnology integrates biotechnology and nanotechnology for developing biosynthetic and environmental-friendly
1.1. Nutraceuticals Nutraceuticals refer to extracts of foods claimed to have medicinal effect on human health. Nutraceuticals are a large and diverse class of compounds, which occur naturally in plants. Although these compounds are considered non-nutritive, many of them possess antioxidant, anti-oestrogenic, antimutagenic, anti-inflammatory and anti-carcinogenic properties that might potentially be beneficial in preventing diseases and protecting the stability of the genome.
