Nanotech In Manufacturing Essay

Description of the technology and explanation of the associated science (Chris)
So what is nanotechnology? Webster dictionary defines nanotechnology as the science of manipulating materials on an atomic or molecular level. Basically nanotechnology is the study and application of matter on the atomic level between 1 and 100 nanometers (nm). A nanometer is one-billionth of a meter. To get an understanding of how small this is, an atom has a diameter of about 0.1nm and the nucleus of an atom is much smaller, about 0.00001nm. Nanotechnology is the science that is used to rearrange molecules on the atomic level so that each atom is essentially put in the most ...view middle of the document...

It can also be argued by historians and some scientists that nanotechnology can be dated back to the 4th century. There is evidence that gold nanoparticles were used in coloring glass in medieval times and possible used even during the Roman Empire to make goblets translucent when lit under a light. For the sake of argument we will discuss the history of nanotechnology beginning in 1959 with Richard Feynmen. Many regard this as the beginning of nanotechnology. In his speech, “There’s Plenty of Room at the Bottom”, Feynmen suggests that is a possibility for scientist to control and manipulate individual atoms and molecules (History of Nanotechnology). This statement was the foreshadowing of nanotechnology. The term nanotechnology was not coined by Richard Feynmen in his speech but by Tokyo Science University Professor Norio Taniguchi in 1974. Professor Taniguchi used the suggested the word to describe the technology that would strive for accuracy at the level of about one nanometer.
Another breakthrough happened in the late 1970’s, by M.I.T undergraduate Eric Drexler. He popularized the word “nanotechnology” by talking about building machines on the scale of molecules. This talk brought up the more radical form of nanotechnology, called Molecular Manufacturing. Drexler describes molecular manufacturing as the production of complex structures through a non-biological assembler, by using a sequence of chemical reactions (Drexler).
The application of nanotechnology has a far reaching impact to the scientific community. Biologist, chemists, physicists and engineers are involved in studying substances at the nano-scale trying to make improvements in some of our daily products. With the advancement in nanotechnology, the science of medicine has been provided a great opportunity for advancement in areas such as cancer diagnostics, imaging, and drug delivery. These advancements have led.... to the potential application of nanotechnology use in the diagnosis and treatment of cancer. By using nanotechnology, you can use nanoparticles to not only increase the dose of a therapeutic drug or imaging contract used in treatment and diagnostic, but it also can be modified for target selectivity toward a tumor cell to increase the image resolution of the cell and also reduce off target...
