Scanning electron microscopy

Histopathology, 1982
The technology of scanning electron microscopy (SEM) is described in brief. Its application to the study of cell and tissue structure is demonstrated and the evolution of the concept of ‘topographical histology’ is discussed. Some current literature on the applications of SEM is reviewed under the headings of experimental pathology and human pathology.

Onychoschizia: Scanning electron microscopy

Journal of the American Academy of Dermatology, 1984
The distal ends of the fingernails of four women with onychoschizia were studied with scanning electron microscopy. The dorsal surface and tip of each nail showed horizontal lamellar separations representing single cell layers. Some cleavage lines extended proximally into the nail plate, revealing remarkable sculptured cell surfaces deep within the ...

Scanning electron microscopy of retinoblastoma

Experimental Eye Research, 1978
Abstract The surface morphology of two continuous cell lines of human retinoblastoma (Y79 and WERI-Rbl) and freshly removed retinoblastoma were studied by scanning electron microscopy (SEM). Commonly observed surface features included microvilli, lamellipodia, filopodia, and zeiotic blebs. A close similarity was seen between the surface morphology of

Stroboscopic scanning electron microscopy

Journal of Physics E: Scientific Instruments, 1968
High frequency cyclic voltages on a specimen surface have been studied pictorially, in the scanning electron microscope, by applying the principle of the sampling oscilloscope. The electron beam in the microscope column is pulsed, and the phase varied with respect to that of the waveform on the specimen.

Scanning electron microscopy of staphylococcus

Journal of Ultrastructure Research, 1977
The surface of Staphylococcus was examined in the field emission source scanning electron microscope and the following observations were obtained. The cell surface consisted of three areas, the smooth, the less smooth and the rough. Two cells were joined together facing each other at the smooth area.

Scanning Electron Microscopy of Cells

Science, 1969
The scanning electron energy-analyzing microscope uses characteristic energy losses to provide picture contrast. At different levels of energy loss particular structures are distinguished with high contrast in an unstained section of a cell.

Scanning electron microscopy of the lung

Human Pathology, 1970
Abstract We have examined the lungs of humans, baboons, pigs, and mice with a scanning electron microscope. The tissues were prepared in various ways, including formalin vapor fixation, freeze drying, and conventional methods of tissue processing for transmission electron microscopy. Glutaraldehyde fixed and alcohol dehydrated tissues presently appear
