Fluorescence Microscopic Methods in Histochemistry

1991
The majority of tissue components in unstained untreated sections show some degree of fluorescence. This is called primary fluorescence or autofluorescence. Such autofluorescence is particularly pronounced in plant tissues, while in animal tissue, collagen, elastin, and lipofuscin are noted for this property.

Bayesian Tracking for Fluorescence Microscopic Imaging

3rd IEEE International Symposium on Biomedical Imaging: Macro to Nano, 2006., 2006
Fluorescence microscopy is a powerful imaging tool for studying molecular dynamics in living cells. For quantitative motion analysis of subcellular structures robust and accurate detection and tracking techniques are necessary sequential Monte Carlo methods, also known as particle filters (PF), have become a tremendously popular tool to perform ...

Breaking the diffraction resolution limit by stimulated emission: stimulated-emission-depletion fluorescence microscopy.

Optics Letters, 1994
We propose a new type of scanning fluorescence microscope capable of resolving 35 nm in the far field. We overcome the diffraction resolution limit by employing stimulated emission to inhibit the fluorescence process in the outer regions of the ...

Development of a new force microscope with a fluorescence optical microscope

Thin Solid Films, 1994
Abstract Combination of observations by conventional fluorescence microscope and recently developed vertical and lateral force microscope (atomic force microscope and frictional force microscope) gives us the two- or three-dimensional configurations, phase transitions and chemical information on the head groups of Langmuir-Blodgett films in a wide ...

FLUORESCENCE MICROSCOPE EXAMINATION OF BACTERIA IN SOIL

Canadian Journal of Research, 1948
By the staining of soil with the fluorescent dye acridinorange and examination of the stained soil under the fluorescence microscope, it is possible to observe directly the living bacteria of soil in their autochthonic condition. All humus substances are stained red in color.

FLUORESCENCE MICROSCOPE EXAMINATION OF TRYPANOSOMES IN BLOOD

Canadian Journal of Research, 1948
With acridinorange it is possible to stain selectively trypanosomes in blood intra-vitam. In subsequent examination by means of a fluorescence microscope only leucocytes and trypanosomes are visible (as shining bright green bodies), while the erythrocytes are not visible.

Designing a Confocal Fluorescence Microscope

1994
The confocal fluorescence microscope (CFM) plays an important role in modern light microscopy. It has enabled a smooth and relatively quick transition from the observation of flat specimens in two dimensions to the observation of thick specimens in three dimensions.
