HORTICULTURE

Detailed explanation-1: -We have hundreds of examples of nanoscience under our eyes daily, from geckos that walk upside down on a ceiling, apparently against gravity, to butterflies with iridescent colours, to fireflies that glow at night.

Detailed explanation-2: -The nanoscopic scale (or nanoscale) usually refers to structures with a length scale applicable to nanotechnology, usually cited as 1–100 nanometers (nm). A nanometer is a billionth of a meter. The nanoscopic scale is (roughly speaking) a lower bound to the mesoscopic scale for most solids.

Detailed explanation-3: -Examples of products already developed or being developed using nanotechnologies include many different consumer products, such as cosmetics, anti-aging skin creams, antiseptics, sheer sunscreens, lighter and stronger sports equipment, water-proof and antimicrobial fabrics, and scratchproof coatings.

Detailed explanation-4: -A sheet of paper is about 100, 000 nanometers thick. A strand of human DNA is 2.5 nanometers in diameter. There are 25, 400, 000 nanometers in one inch. A human hair is approximately 80, 000-100, 000 nanometers wide.
