| interference reflection microscopy | <procedure> An optical technique for detecting the topography of the side of a cell in contact with a planar substrate and for providing information on the separation of the plasmalemma from the substrate. Interference between the reflections from the substrate medium interface and the reflections from the plasmalemma medium interface generate the image. (18 Nov 1997) |

| time-lapse microscopy | Microscopy in which the same object (e.g., a cell) is photographed at regular time intervals over several hours. (05 Mar 2000) |
| electron microscopy | <procedure> Any form of microscopy in which the interactions of electrons with the specimens are used to provide information about the final structure of that specimen. In transmission electron microscopy the diffraction and adsorption of electrons as the electron beam passes normally through the specimen is imaged to provide information on the specimen. In scanning electron microscopy an electron beam falls at a nonnormal angle on the specimen and the image is derived from the scattered and reflected electrons. Secondary X-rays generated by the interaction of electrons with various elements in the specimen may be used for electron microprobe analysis. (18 Nov 1997) |
| transmission electron microscopy | <technique> Those forms of electron microscopy in which electrons are transmitted through the object to be imaged, suffering energy loss by diffraction and to a small extent by absorption. Acronym: TEM (18 Nov 1997) |
| fluorescence microscopy | <procedure> Any type of microscopy in which intrinsic or applied reagents are visualised. Intrinsic fluorescence is often referred to as auto fluorescence. The applied reagents typically include fluorescently labelled proteins that are reactive with sites in the specimen. In particular, fluorescently labelled antibodies are widely used to detect particular antigens in biological specimens. (18 Nov 1997) |
| light microscopy | <procedure> In contrast to electron microscopy. See: bright field, phase contrast, interference, interference contrast, interference reflection, dark field, confocal and fluorescence microscopy. (18 Nov 1997) |
