To understand the concepts of nanotechnology and its uses, we must first get an understanding of what nanotechnology is. The size of a nanometer is a billionth of a meter, or 10-9 of a meter. To illustrate the size of a manometer, picture 100,000 manometers as the thickness of a sheet of newspaper. It also takes 25,000,000 manometers to make up one inch. On a comparative scale, if a marble were a nanometer, then one meter would be the size of the Earth (What is Nanotechnology, retrieved 1/13/15).

Everything around us is made up of atoms; our bodies, food we eat and the clothes we wear, houses we live in, and the air we breathe. All we touch, see, and smell are made up of atoms. None of the atoms that make up our world can be seen with the naked eye or with a typical microscope that is used in high school science labs. If an atom cannot be seen with a regular microscope, then a manometer will definitely not be seen either. In order to see what a nanometer is, a special microscope was invented about 30 years ago, which now makes it easier to see nanometers in larger scales.

While nanotechnologies in our modern life are relatively new, ancient people have used them for centuries. Alternate-sized gold and silver particles created colors in the stained glass windows of medieval churches hundreds of years ago. The artists back then just did not know that the process they used to create these beautiful works of art actually led to changes in the composition of the materials they were working with. Today's scientists and engineers are finding a wide variety of ways to deliberately make materials at the nanoscale to take advantage of their enhanced properties such as higher strength, lighter weight, increased control of light spectrum, and greater chemical reactivity than their larger-scale counterparts are.

Nanotechnology, which has often been called a new technique, has the potential to influence our society in just about every area of our lives. While nanotechnology is being used in such products as sunscreen and cosmetics, it is also being used to improve everything from batteries to electronic equipment. One of the biggest areas of nanotechnology is in its use in the medical science research field. Because the medical field deals with things on the smallest of levels, the use of nanotechnology prove to be very beneficial for those who are facing cancer and heart disease. To help in the medical field, nanobots have been created to perform many different functions inside and outside of the human body, such as repairing a body’s cells or operating on a baby while still in the womb. Without the use of nanobots, doctors would not have otherwise been able to perform such delicate research or surgeries. While medical specialists, such as those in cancer research centers, heart specialists, and other medical professions are using nanotechnology in their field, The National Cancer Institute, in the hopes that investments in this branch of nanomedicine, has created the alliance for Nanotechnology in Cancer. This is in the hopes that investments could help in detection and treatment of different types of cancers. The National Cancer Institute states that several nanocarrier-based drugs are already on the market and many more are still in clinical trials; these clinical trials could help in the cure of certain types of cancers. Nanotechnology can provide rapid and sensitive detection of cancer-related molecules, enabling scientists to detect molecular changes even when they occur only in a small percentage of cells. Nanotechnology also has the...
