Scanning ultrafast electron microscopy [PDF]

open access: yesProceedings of the National Academy of Sciences, 2010
Progress has been made in the development of four-dimensional ultrafast electron microscopy, which enables space-time imaging of structural dynamics in the condensed phase. In ultrafast electron microscopy, the electrons are accelerated, typically to 200 keV, and the microscope operates in the transmission mode.

SCANNING ELECTRON MICROSCOPY [PDF]

open access: yesJournal of the Royal Microscopical Society, 1964
Abstract Scanning electron microscopy is a method of microscopy that permits resolution better than that of the optical microscope (about 100 A) while examining one surface of a bulk specimen. The technique depends on electronic application to microscopy and has been developed over many years by electronic engineers rather than physicists or ...

Transmission and scanning electron microscopy of cutis rhomboidalis

open access: yesAnais Brasileiros de Dermatologia, 2021
Cutis rhomboidalis nuchae was assessed in a 65-year-old patient. Optical microscopy showed basophilic agglomerations in the reticular dermis with decreased elastic fibers.

Correlative photoactivated localization and scanning electron microscopy. [PDF]

open access: yesPLoS ONE, 2013
The ability to localize proteins precisely within subcellular space is crucial to understanding the functioning of biological systems. Recently, we described a protocol that correlates a precise map of fluorescent fusion proteins localized using three ...

Cryoprotection of porcine cornea: a scanning electron microscopy study

open access: yesVeterinární Medicína, 2005
Porcine corneas were frozen with Me2SO, glycerol, 1,2-propanediol and PEG-400. The effects of the range of concentrations (5% and 10%) and temperature regimen (1ºC/min and 5ºC/min) were investigated.

Simultaneous correlative scanning electron and high-NA fluorescence microscopy. [PDF]

open access: yesPLoS ONE, 2013
Correlative light and electron microscopy (CLEM) is a unique method for investigating biological structure-function relations. With CLEM protein distributions visualized in fluorescence can be mapped onto the cellular ultrastructure measured with ...

Flash Scanning Electron Microscopy [PDF]

open access: yes, 2013
Scanning Electron Microscopy (SEM) is an invaluable tool for biologists and neuroscientists to study brain structure at the intracellular level. While able to image tissue samples with up to 5 nm isotropic resolution, image acquisition is prohibitively slow and limits the size of processed samples.

Cell–Cell and Cell–Matrix Interactions at the Presumptive Stem Cell Niche of the Chick Corneal Limbus

open access: yesCells, 2023
(1) Background: Owing to its ready availability and ease of acquisition, developing chick corneal tissue has long been used for research purposes. Here, we seek to ascertain the three-dimensional microanatomy and spatiotemporal interrelationships of the ...
