  2. Fluorescence microscope - Wikipedia

    en.wikipedia.org/wiki/Fluorescence_microscope

    Multi-color images of several types of fluorophores must be composed by combining several single-color images. [1] Most fluorescence microscopes in use are epifluorescence microscopes, where excitation of the fluorophore and detection of the fluorescence are done through the same light path (i.e. through the objective).

  3. Fluorescence imaging - Wikipedia

    en.wikipedia.org/wiki/Fluorescence_imaging

    Multicolor fluorescence image of living HeLa cells. Fluorescence imaging is a type of non-invasive imaging technique that can help visualize biological processes taking place in a living organism. Images can be produced from a variety of methods including: microscopy, imaging probes, and spectroscopy.

  4. Two-photon excitation microscopy - Wikipedia

    en.wikipedia.org/wiki/Two-photon_excitation...

    Two-photon excitation microscopy of mouse intestine.Red: actin.Green: cell nuclei.Blue: mucus of goblet cells.Obtained at 780 nm using a Ti-sapphire laser.. Two-photon excitation microscopy (TPEF or 2PEF) is a fluorescence imaging technique that is particularly well-suited to image scattering living tissue of up to about one millimeter in thickness.

  5. Fluorescence-lifetime imaging microscopy - Wikipedia

    en.wikipedia.org/wiki/Fluorescence-lifetime...

    Fluorescence-lifetime imaging microscopy or FLIM is an imaging technique based on the differences in the exponential decay rate of the photon emission of a fluorophore from a sample. It can be used as an imaging technique in confocal microscopy , two-photon excitation microscopy , and multiphoton tomography.

  6. Microscope image processing - Wikipedia

    en.wikipedia.org/wiki/Microscope_image_processing

    Microscope image processing is a broad term that covers the use of digital image processing techniques to process, analyze and present images obtained from a microscope. Such processing is now commonplace in a number of diverse fields such as medicine, biological research, cancer research, drug testing, metallurgy, etc. A number of ...

  7. Light sheet fluorescence microscopy - Wikipedia

    en.wikipedia.org/wiki/Light_sheet_fluorescence...

    Light sheet fluorescence microscopy (LSFM) is a fluorescence microscopy technique with an intermediate-to-high [1] optical resolution, but good optical sectioning capabilities and high speed. In contrast to epifluorescence microscopy only a thin slice (usually a few hundred nanometers to a few micrometers) of the sample is illuminated ...

  8. Photoactivated localization microscopy - Wikipedia

    en.wikipedia.org/wiki/Photoactivated...

    Conventional fluorescence microscopy is performed by selectively staining the sample with fluorescent molecules, either linked to antibodies as in immunohistochemistry or using fluorescent proteins genetically fused to the genes of interest. Typically, the more concentrated the fluorophores, the better the contrast of the fluorescence image.

  9. Immunofluorescence - Wikipedia

    en.wikipedia.org/wiki/Immunofluorescence

    IF can additionally be used in combination with other, non-antibody methods of fluorescent staining, e.g., the use of DAPI to label DNA. [10] [11] Examination of immunofluorescence specimens can be conducted utilizing various microscope configurations, including the epifluorescence microscope, confocal microscope, and widefield microscope.
