Spectral Detection – How to Define the Spectral Bands that Collect Probe-specific Emission
To specifically collect emission from multiple probes, the light is first separated spatially and then passes through a device that defines a spectral band. Classically, this is a common glass-based…
Nobel Prize 2012 in Physiology or Medicine for Stem Cell Research
The Nobel Prize recognizes two scientists who discovered that mature, specialised cells can be reprogrammed to become immature cells capable of developing into all tissues of the body. Their findings…
Fluorescence Correlation Spectroscopy (FCS)
Fluorescence correlation spectroscopy ( FCS ) measures fluctuations of fluorescence intensity in a sub-femtolitre volume to detect such parameters as the diffusion time, number of molecules or dark…
White Light Laser
The perfect light source for confocal microscopes in biomedical applications has sufficient intensity, tunable color and is pulsed for use in lifetime fluorescence. Furthermore, it should offer means…
Fluorescence Recovery after Photobleaching (FRAP) and its Offspring
FRAP (Fluorescence recovery after photobleaching) can be used to study cellular protein dynamics: For visualization the protein of interest is fused to a fluorescent protein or a fluorescent dye. A…
Förster Resonance Energy Transfer (FRET)
The Förster Resonance Energy Transfer (FRET) phenomenon offers techniques that allow studies of interactions in dimensions below the optical resolution limit. FRET describes the transfer of the energy…
Mosaic Images
Confocal laser scanning microscopes are widely used to create highly resolved 3D images of cells, subcellular structures and even single molecules. Still, an increasing number of scientists are…
Confocal Optical Section Thickness
Confocal microscopes are employed to optically slice comparably thick samples.
