    • Francisco J. Fuster<br />March 25, 2011<br />Nanotechnology and Electron Microscopy<br /> Nanotechnology is being applied to many technological advances like the formation of microchips for computers. This is one reason why these new applications get outdated really fast. This type of research is focused on molecules smaller than 100nm scale. The hypothesis is that by being smaller there is more surface area than volume, adding strength to these materials. The advantage is that if it is applied for chips, the sensitivity will be higher and it will give off a reading a lot faster than a full sized chip, because it is so small that the reading has to travel over less surface area.<br /> Hidroxyapatite is another focus in this lab. It is being applied to the recovering of metal limb implants. The hydroxyapatite makes up 67% of bone composition. This is an advantage because it occurs naturally in the human body. The covering of these metallic limbs, add durability to them because the blood found in the body is corrosive. The hydroxyapatite protects these limbs from corrosion.<br /> The last part making up this investigation is the electron microscopy. This type of microscopy consists of the integration of electrons to replace the ordinary microscopic lens. What the electrons do is that they hit the specimen being observed, take out those in the position and replace them with the electrons shot out of the microscope. These electrons are marked so that the microscope can locate them and identify them by viewing the image. <br />
