Confocal microscopy [PDF]

, 2011
Chapter focusing on confocal microscopy. A confocal microscope is one in which the illumination is confined to a small volume in the specimen, the detection is confined to the same volume and the image is built up by scanning this volume over the ...

X-ray computerized microtomography and confocal Raman microscopy as complementary techniques to conventional imaging tools for the microstructural characterization of Cheddar cheese

Journal of Dairy Science, 2022
: This study explored the use of X-ray computerized microtomography (micro-CT) and confocal Raman microscopy to provide complementary information to well-established techniques, such as confocal laser scanning microscopy (CLSM), for the microstructural ...

Raman imaging of protein in a model cheese system

Journal of Spectral Imaging, 2020
Raman confocal microscopy is an increasingly useful technique when applied to food samples; it has the unique ability to interrogate the chemical structure, aligned with the same confocality capability that is available when using standard confocal ...

Evaluating performance in three-dimensional fluorescence microscopy [PDF]

, 2007
In biological fluorescence microscopy, image contrast is often degraded by a high background arising from out of focus regions of the specimen. This background can be greatly reduced or eliminated by several modes of thick specimen microscopy, including ...

Confocal Raman data analysis enables identifying apoptosis of MCF-7 cells caused by anticancer drug paclitaxel [PDF]

, 2013
Confocal Raman microscopy is a noninvasive, label-free imaging technique used to study apoptosis of live MCF-7 cells. The images are based on Raman spectra of cells components, and their apoptosis is monitored through diffusion of cytochrome c in ...
