Depending upon the microscope used and the preparation technique, an entire intact organism, or thin slices through the interior of the sample can be examined by electron microscopy. The electron beam can pass through very thin sections of a sample...

Described by the Nobel Society as "one of the most important inventions of the century," the electron microscope is a valuable and versatile research tool. The first working models were constructed by German engineers Ernst Ruska and Max Knoll in 1932,...

Literally, freezing tissue and fracturing it. Scanning ELECTRON MICROSCOPY is then used to examine the fractured tissue surface. The point of freeze fracture is that tissue (or indeed anything else) will break under pressure along the line of least...

An electron microscope is a type of microscope that uses electrons to illuminate a specimen and create an enlarged image. Electron microscopes have much greater resolving power than light microscopes and can obtain much higher magnifications. Some...

The environmental scanning electron microscope (ESEM) is a new tool for imaging textile specimens without the need to coat or dry them in advance. Researchers from Heriot-Watt University describe some of their results. I canning electron microscopes (SEMs) are instruments that use...

Electron microscopes are a practical application of the principle that the waves associated with matter really do matter. Electron waves are very much shorter than light waves, so using electrons as probes instead of light reveals finer details, usually about the atomic and...

Inventor James Hillier, who helped develop and market the first commercially successful electron microscope in the United States and found uses for it in medical research, has died at age 91.Hillier died Jan. 15 at a Princeton hospital after suffering a stroke, according to his...

A new microscope offers a glimpse of the future of nanotechnology research. At least, that's the hope of the microscope's maker, FEI.The Hillsboro, Ore., company last week started selling its Phenom microscope, which it bills as the first affordable and easy-to-use scanning electron microscope. True,...
