Nanotechnology is the study and use of structures between 1 nanometer and 100 nanometers in size. To give you an idea of how small that is, it would take eight hundred 100 nanometer particles side by side to match the width of a human hair. Scientists have been studying and working with nanoparticles for centuries, but the effectiveness of their work has been hampered by their inability to see the structure of nanoparticles. Nanotechnology is the science and creation of materials at a molecular level. Nanotechnology applications are used in medicine, chemistry, the environment, energy companies, and communication. The use of nanotechnologies in medicine has provided many medical breakthroughs. Some of the medical nanotechnology applications are for diagnostics. These are used to assist in identifying DNA and helping detect genetic sequences. The book will serve as an ultimate resource book for everyone who would like to know the wide range of prospects in the emerging applications of Nanotechnology.
