When nanotechnology will be in its mature form it is sure it will have its impact upon almost every industries land almost every area of society from communication to medicine, from agriculture to transportation and also in smarter living at home also. And because of these implications only nanotechnology is also called as general purpose technology. As a general-purpose technology, it will have multiple uses, not only in commercial field as well as in defence field too that will include making of far more powerful and better weapons and equipments for infantry, air force and navy. Nanotechnology is about building machines at the molecular level. Machines so small they can travel through our blood stream.

Nanotechnology will allow making high-quality products at a very low cost, and also allow making new nanofactories at the same low cost and at a very rapid speed. Nanotechnology offers not just better products, but a vastly improved means of production for e.g. as many copies of data files as we want can be taken out from your computer at a very or no cost. With time, manufacture of products will become as cheap as the copying of files. So this is what nanotechnology is, and so it is often seen as the next industrial revolution. Nanoscale materials are used in electronic, magnetic and optoelectronic, biomedical, pharmaceutical, cosmetic, energy, catalytic and materials applications.

The word nano we are talking about is not a smallest thing on the planet or in space. The protons, neurons, quarks, leptons and neutrinos are considered as the family of electrons out of which quarks and leptons are the smallest known particles. Protons, neutrons, pions, quarks, are some other sub-atomic particles are smaller than electrons. Nanotechnology is the manufacturing of electronic circuits and mechanical devices by using these particles that means working at molecular level, with takings every particle, every molecule and every atom in concerned. In this way scientist can prepare a structure and material that will have absolutely new characteristics and function. It is about to emerge as a technology which is a revolutionary, transformative, powerful, and potentially very dangerous or beneficial technology called The exponential technology.

In fact, there will not be a single industry that will not be changed by nanotechnological applications. Be it a tennis racquets or long-lasting nanoparticle tennis balls. A foot warmers, athlete skin care or a ski wax. Nanotechnology, nowadays is progressing towards the delivery system for anti-cancer drugs at the same time research is going on to develop nanofibre which will help create blood vessels, help in treatment of vascular diseases and in heart surgeries. The purpose of medical devices and nanorobots traveling through the human body is essentially a positive one of searching out and destroying clusters of cancer cells before they spread. Scientists are also working towards the preparation of injectable nanoparticles that will help as medication for treating alcoholism and other related diseases. Because of this it is also called as the future technology.

A lot of money is being invested in this field. In 2004, USA invested more than $400 million into the research area of nanotechnology, facilities, and business development programs and a lots more in the area of publicity is being poured in. On a global scale, these figures multiply exponentially. Even private firms are pumping up a lot amount of money over two billon dollars a year along with the government in the field of nanotechnology.
