What is Nanotechnology?
Over the past few decades, the development of new and more advanced energy technologies with the capability of improving life all over the world have been sought in the field of science and engineering. In order to make the next leap forward from the current generation of technology, scientists and engineers have been developing the new field of science called Nanotechnology.
Nanotechnology is defined as the science and technology of building electronic circuits and devices from single atoms and molecules, or the branch of engineering that deals with things smaller than 100 nanometers. A nanometer (nm) is one billionth of a meter, roughly the width of three or four atoms. For scale comparison, the average human hair is about 80,000 nanometers wide, and a single virus particle is about 100 nanometers in width. The prefix nano- comes from the Greek words nanos, meaning “dwarf.” The term Nanotechnology is also often used to describe the interdisciplinary fields of science devoted to study and use of nanoscale phenomena.
The story of nanotechnology began in the 1950s and 1960s, when the most engineers were thinking big not small. This was era of big cars, big jets, the world’s largest oil tankers, huge skyscrapers and big plans for sending people into outer space. Other researchers, however, focused on making things small. The invention of the transistor in 1947 and the first integrated circuit(IC) in 1959 launched an era of electronics miniaturization. It was these small devices that made large devices, such as spaceships, possible. After successfully splitting the atom in the years before World War II, physicist tried to understand about the particles from which atoms are made, and the forces that bind them together. At the same time, chemists worked to combine atoms into new kinds of molecules, and had great success in converting the complex molecules of petroleum into all sorts of useful plastic.

Nanomedicine
Nanomedicine is an area of biomedical research that seeks to use tools from the field of nanotechnology to improve health. Scientists say that physical, chemical, and biological properties of materials at the nanoscale differ in fundamental way from the properties of large–sized matter. For example, nanotechnology could provide new formulations and new routes to deliver drugs to previously inaccessible sites in the body, thereby broadening a drug’s potential. Tiny sensors, that detect diseases in the body far earlier than existing diagnostic tools, are among the promising areas of research. In today’s world of biomedical tools and therapies, pocket–sized electrocardiographs for monitoring the heart have appeared, and diagnostic cameras the size of a vitamin can travel the length of a digestive tract. The extremely small size of nanomaterials also means that they are much more readily absorbed by a human body than large-sized particles.
