Examination of minute objects by use of an electron microscope.
Medical Dictionary for the Health Professions and Nursing © Farlex 2012
electron microscopyA method of producing a greatly enlarged image of very small objects by using a beam of accelerated electrons instead of light. Modern instruments enable objects smaller than 1nm (one millionth of a millimetre) to be seen. This is almost down to atomic level. Focusing is done by means of magnetic fields obtained from charged plates or current-carrying coils. These fields act as lenses. Electron microscopes are essential tools in medical research and diagnosis.
