Electron microscope

The electron microscope is a type of microscope that uses electrons to create an image of the target.

It has much higher magnification or resolving power than a normal light microscope.

Although modern electron microscopes can magnify objects up to two million times, they are still based upon Ruska's prototype and his correlation between wavelength and resolution.

The electron microscope is an integral part of many laboratories.

Researchers use it to examine biological materials (such as microorganisms and cells), a variety of large molecules, medical biopsy samples, metals and crystalline structures, and the characteristics of various surfaces.

Gerd Binnig Chemistry Under the Microscope

Gerd Binnig Chemistry Under the Microscope

Deutsche Welle (July 7, 2013) He opened up a new world, paving the way for nanotechnology. Gerd Binnig shared the 1986 Nobel Prize in Physics for the invention of the scanning tunneling microscope. For the first time, the invention made it possible to see individual atoms and manipulate them. Chemistry had become engineering. Ever since, information scientists, chemists and materials scientists have been using Binnigs inventions to create materials with made-to-measure properties, in particular for microelectronics. Binnig himself started up a company that develops software to automatically analyze microscope images - for example, to recognize tumor cells. Tomorrow Today presents a portrait of the Nobel laureate.
