Handbook of Optical Filters for Fluorescence Microscopy
Fluorescence microscopy and other light-based applications require optical filters that have demanding spectral and physical characteristics. Often, these characteristics are application-specific and…
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…
Step by Step Guide for FRAP Experiments
Fluorescence Recovery After Photobleaching (FRAP) has been considered the most widely applied method for observing translational diffusion processes of macromolecules. The resulting information can be…
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…
The Principles of White Light Laser Confocal Microscopy
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…
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…
An Introduction to CARS Microscopy
CARS overcomes the drawbacks of conventional staining methods by the intrinsic characteristics of the method. CARS does not require labeling because it is highly specific to molecular compounds which…
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…
