Fluorescence Microscopy Principle
For apa capsules alginate can be labeled with the fluorochrome fluoresceinamine and poly l lysine can be labeled with alexa 546 protein labeling kit strand et al 2003.
Fluorescence microscopy principle. A fluorescence microscope is an optical microscope that uses fluorescence and phosphorescence instead of or in addition to scattering reflection and attenuation or absorption to study the properties of organic or inorganic substances. Confocal laser scanning microscopy clsm is another powerful tool to visualize polymer gels labeled with fluorescent ligands. Confocalnl aims to change the microscopy industry with a confocal microscope based on the re scan invention. The measurement principle is based upon a physical characteristic of aromatic hydrocarbons.
Fluorescence is a long established measurement technique and the most widespread technique for measuring oil in water. Visser 12 and olaf j. Light sheet fluorescence microscopy lsfm is a fluorescence microscopy technique with an intermediate to high optical resolution but good optical sectioning capabilities and high speed.
