WHEN an unstained preparation is viewed through the microscope by transmitted light (substage), light parts of it may appear black for one of two reasons: either they absorb much light or they reflect ...

Microscopy continues to transform the life sciences. Here are five recent breakthroughs made possible by the technique.

Reflection-contrast microscopy is a type of light microscopy that can be used to analyze single cells, biopsies, and other small objects. In contrary to most light microscopy techniques, ...

Transmission Electron Microscopes can be used for a variety of different techniques, which set them apart from other forms of microscope. The first is metal shadowing or negative staining. TEM ...

Several light sources produce light across various wavelengths. While this wavelength spectrum can be useful in lighting applications, other applications require light with a restricted visible ...

Conventional light microscopy has its limits. Light, being a wave, is subject to diffraction which severely limits the size of structures one can resolve. To be able to observe parts of an organism ...

Materials scientists can learn a lot about a sample material by shooting lasers at it. With nonlinear optical microscopy—a specialized imaging technique that looks for a change in the color of intense ...
