Recent advances in electron microscopy and diffraction have increasingly focused on capturing dynamical processes at unprecedented temporal resolutions. Ultrafast electron microscopy and diffraction ...

While confocal microscopy uses a pinhole to reject out-of-focus light to generate the optical section, a multi-photon (or 2-photon) microscope uses a pulsed infrared laser to stimulate fluorescence ...

Stimulated emission depletion (STED) microscopy has shown that diffraction-unlimited spatial resolution is viable with conventional lenses and visible light. Stefan W Hell, Lars Kastrup and Katrin I ...

Raman microscopy combines optical microscopy with the ability to determine the chemical makeup of surfaces. Laser light is delivered to the sample surface via the same objective as the optical light ...

Fluorescence light microscopy techniques offer several advantages when imaging biological samples, including high image contrast, good labeling specificity, multicolor, and three dimensional (3D) ...

A research team has created a fluorescent marker molecule that does not degrade under a STED microscope: the photobleaching problem has been solved. Images of living cells can now be captured over ...

It’s relatively easy to understand how optical microscopes work at low magnifications: one lens magnifies an image, the next magnifies the already-magnified image, and so on until it reaches the eye ...

Researchers from the University of Science and Technology of China (USTC) have unveiled a planar optical device that significantly enhances the capabilities of dark-field microscopy, achieving ...

Imagine owning a camera so powerful it can take freeze-frame photographs of a moving electron—an object traveling so fast it could circle the Earth many times in a matter of a second. Researchers at ...
