Interference reflection microscopy in cell biology: methodology and applications.
Since its introduction into cell biology by Curtis in 1964, interference reflection microscopy (IRM) has been used by an increasing number of researchers to study cell-substrate interactions in living cells in culture. With the use of antiflex objectives, high-contrast IRM images can now be readily obtained. From the different theories on image formation in IRM that have been put forward, it ca...
متن کاملHyperspectral Fourier transform spectrometer for reflection spectroscopy and spectral self-interference fluorescence microscopy.
A hyperspectral Fourier transform spectrometer has been developed for studying biological material bound to optically reflecting surfaces. This instrument has two modes of operation: a white-light reflection mode and a spectral self-interference fluorescence mode. With the combined capability, information about the conformation of an ensemble of biomolecules may be determined. To the best of ou...
متن کاملEffects of phase change on reflection in phase-measuring interference microscopy.
We show by analytical and numerical calculations that the phase change on reflection that occurs in interference microscopy is almost independent of the numerical aperture of the objective. The shift of the microscope interferogram response due to the phase change on reflection, however, increases with the numerical aperture. Measurements of the interferogram shift are made with a Linnik interf...
متن کاملInteraction between intracellular vacuoles and the cell surface analysed by finite aperture theory interference reflection microscopy.
Using finite aperture theory we have shown that localized very dark areas in the interference reflection images of Dictyostelium discoideum amoebae are due to the close intracellular approach of vesicles and tubular elements of the contractile vacuole system to the plasma membrane adjacent to the substratum. Vesicles interacting in this way become locally deformed to the planar contour of the s...
متن کاملUse of a white light supercontinuum laser for confocal interference-reflection microscopy
Shortly after its development, the white light supercontinuum laser was applied to confocal scanning microscopy as a more versatile substitute for the multiple monochromatic lasers normally used for the excitation of fluorescence. This light source is now available coupled to commercial confocal fluorescence microscopes. We have evaluated a supercontinuum laser as a source for a different purpo...
