Core Of Nanotechnology: Nanotechnology is defined as 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 equal the width of a human hair. As this is the most common definition of nanotechnology but scientist with various focuses have slightly different Definitions of Nanotechnology. Preface to Nanotechnology: Looking At Nanoparticles Researcher 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. In recent decades the development of advanced microscopes capable of displaying particles as small as atoms has allowed researcher to see what they are working with. The following illustration titled “The Scale of Things”, created by the U. S. Department of Energy, provides a comparison of various objects to...
