Microscope digital images

Single-walled carbon nanotubes (SWNTs) obtained in the Rice University, Houston, were investigated in high resolution mode (0.335 nm) using a Philips 420 transmission electron microscope. Digital images were captured at the atomic lev-... 

The STATPack consultation process involves capturing macroscopic and/or microscopic digital images of culfure samples, or possibly original clinical specimens, and sending them electronically to experts at state public health laboratories for consulfafion. STATPack... 

This substance penetrates into the cell where it is hydrolysed to fluorescein through the action of the enzyme s esterases. The quantity of the fluorescent quinoid form then depends on the local value of pH in the same way as in the case of phenolphthalein. The intensity of the fluorescein radiation is measured with a fluorescence microscope and then processed to a digital image which is the basis of a map of pH distribution in the cell (Fig. 1.13). 

Martens and Thybo (2000) used digital image analysis of scanning electron microscope images of potato tissue and of starch to successfully relate microstmcture characteristics to textural properties. 

Figure 4.11 A three-dimensional reconstruction of multiphoton microscope acquired image slices of a series of small vessels in the dorsal skinfold window chamber. Taken with a 40x water immersion objective and digitally zoomed to approximately 60x.

Image processing. Digital images of the prepared sections were acquired by light microscopy. The light microscope (Zeiss Universal... 

For the estimation of Chi formation in hairy roots, the root cells were examined on a laser scanning confocal image system attached to a microscope. The filter package with a laser (excitation 568 nm) and a 590-610 nm band pass barrier filter for red fluorescence was employed. Digital image analysis was performed by a computer-aided image processing system with software. 

The application of in situ hybridization (ISH) has advanced from short lived, non-specific isotopic methods, to very specific, long lived, multiple color fluorescent-ISH probe assays (FISH). Improvements in the optics, filter technology, microscopes, cameras, and data handling by software, have allowed for a cost effective FISH setup to be within reach of most researchers. The application of mFISH (multiplex-FISH), coupled to the advances in digital imaging microscopy, have vastly improved the capabilities for non-isotopic detection and analysis of multiple nucleic acid sequences in chromosomes and genes (1). 

The techniques of FISH and mFISH used in conjunction with the resolving power and automated digital imaging capabilities of the fluorescence microscope offer a powerful combination of advantages that stand to benefit many areas of biology, from basic research to prenatal disease detection, cancer research, pathology, and cytogenetics. 

Scanner Automated microscope that scans a complete slide and stores a digital image of the slide as a virtual slide. 

A novel flow cell has been developed to observe on a microscopic level the steady state, cocurrent flow of two pre-equilibrated phases in a porous medium. It consists of a rectangular capillary tube packed with a bilayer of monodisperse glass beads 109 microns in diameter. The pore sizes in the model are of the order of magnitude of those in petroleum reservoirs. An enhanced videomicroscopy and digital imaging system is used to record and analyze the flow data.
