Fluorescence microscopy techniques are powerful tools for probing very small signals and revealing three-dimensional (3D) structural and functional properties of biological samples with high ...

Techniques such as two-photon excitation microscopy can reveal important information about cellular activity in the brain, but successfully applying the technique to live subjects is far from trivial.

Polytec's optical measurement equipment focuses on dynamic response measurements. MEMS devices typically have actively moving ...

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 ...

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 ...

Tucson-headquartered scientific camera specialist Photometrics says that thanks to a collaboration with the Netherlands-based microscopy startup Confocal.nl, laboratories are now able to buy a new ...

Three-dimensional imaging is dramatically expanding the ability of researchers to examine biological specimens, enabling a peek into their internal structures. And recent advances in X-ray diffraction ...

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

Nanoscopy is a field of microscopy that focuses on imaging and studying structures and processes at the nanoscale, typically below the diffraction limit of light. It encompasses various techniques ...

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 ...
