I. Introduction : Nanotechnology has potential to solve problems related to human civilizations pertaining to both basic needs and aspirations for comfort life. The basic needs of human being are food, drinking water, energy, cloth, shelter, health and clean environment. The aspirations for comfort life are realizing the automation in every field, space travel and expanded life-span and so on. Due to continuous efforts of scientists and engineers during last 30 years, there is a substantial progress in realizing the nanotechnology based components and products in different areas including agriculture, food product and packaging, purification of water, automobiles, atmospheric cleaning, renewable energy, energy storage, consumer goods, sports…show more content…
ABCD Framework of Nanotechnology : Based on the potential ability of nanotechnology as general purpose technology and is considered as “anticipated breakthrough technology of 21st century” to solve all human problems and elevate them to highest comfortability, it is essential to know the detailed advantages, benefits, constraints and disadvantages of progress in nanotechnology for the society. (a) Advantages of Nanotechnology : Advantage is the quality of having a superior or more favorable position. It can be any state, circumstance, opportunity, or means specially favorable to success, interest, or any desired end. Some of the important advantages of nanotechnology are : (1) Nanomaterials are more efficient materials with very useful characteristics in terms of strength, lightness, ductility, extreme small size, thermal and electrical conductibility, and water repellency. (2) Usage of nanomaterials as raw material, machine or equipment reduces the size. (3) Nanotechnology ideas can be applied and implemented to solve almost any problem ever…show more content…
On the other hand, the obscurity of the form of future nanotechnology has bred some end-of-the-world scenarios. The most famous one is known as “Grey goo” which is a hypothetical end-of-the-world scenario involving molecular nanotechnology in which out-of-control self-replicating robots consume all matter on Earth while building more of themselves, a scenario known as ecophagy (“eating the environment”). Alternatively, the most dangerous outcome of molecular nanotechnology would be non-replicating weapons which are easier to
