The document discusses electron microscopes and nanotechnology. It focuses on the Scanning Electron Microscope (SEM) which uses electron beams to examine superficial areas of samples. SEMs allow magnification beyond 1000x since electrons have no wavelength. This enables viewing much smaller samples. The document also discusses how nanotechnology allows manipulation of systems 100 nanometers or smaller. Nanotechnology provides opportunities to study quantum confinement, chemical reactivity, and sensitivity changes. Applications include using nanoparticles for biomedical research like destroying cancer cells. Researchers are also developing fibers using nanotechnology that could eventually be implanted in humans.

1. Nanotechnology and Electron Microscopy
During this workshop we learned about several types of electron microscopes,
specifically the Scanning Electron Microscope (SEM). SEM’s use electron beams to examine a
small superficial area of the sample. Basically the sample is being bombarded by electron
beams and the electrons that bounce back are the ones that project the image. Electron
microscopes are beneficial because they are not limited to a 1000x magnification. Since
electron microscopes have no wave length we can see much smaller samples, opening an
entirely new range of study. For this workshop we also talked about the works being done
regarding nanotechnology. Nanotechnology is a science that allows us the ability to fiscally
manipulate systems that are one hundred nanometers or smaller. Nanotechnology provides a
wide range of study for infinitely small particles. It allows the study of quantum confinement,
chemical reactivity, and alterations in levels of sensitivity. All of these applications can be used
for biomedical research. For example using nanoparticles to destroy and eliminate cancer cells.
With nanotechnology they are developing research related to fibers. They are trying to grow
and study fibers that can eventually be used in human beings.
