  2. Piezospectroscopy - Wikipedia

    en.wikipedia.org/wiki/Piezospectroscopy

    As opposed to other methods of stress measurement, such as powder diffraction or the use of a strain gauge, piezospectroscopy can measure internal stresses at higher resolution, on the order of 1 μm, and can measure very quickly, with most systems taking less than one second to acquire data.

  3. Near-field scanning optical microscope - Wikipedia

    en.wikipedia.org/wiki/Near-field_scanning...

    The nanofocusing technique can create a nanometer-scale "white" light source at the tip apex, which can be used to illuminate a sample at near-field for spectroscopic analysis. The interband optical transitions in individual single-walled carbon nanotubes are imaged and a spatial resolution around 6 nm has been reported. [28]

  4. Nuclear magnetic resonance spectroscopy of proteins

    en.wikipedia.org/wiki/Nuclear_magnetic_resonance...

    This in turn causes the peaks to become broader and weaker, and eventually disappear. Two techniques have been introduced to attenuate the relaxation: transverse relaxation optimized spectroscopy (TROSY) [25] and deuteration [26] of proteins. By using these techniques it has been possible to study proteins in complex with the 900 kDa chaperone ...

  5. Photoluminescence - Wikipedia

    en.wikipedia.org/wiki/Photoluminescence

    The relaxation processes can be studied using time-resolved fluorescence spectroscopy to find the decay lifetime of the photoluminescence. These techniques can be combined with microscopy, to map the intensity (confocal microscopy) or the lifetime (fluorescence-lifetime imaging microscopy) of the photoluminescence across a sample (e.g. a ...

  6. Methods to investigate protein–protein interactions - Wikipedia

    en.wikipedia.org/wiki/Methods_to_investigate...

    With fluorescence correlation spectroscopy, one protein is labeled with a fluorescent dye and the other is left unlabeled. The two proteins are then mixed and the data outputs the fraction of the labeled protein that is unbound and bound to the other protein, allowing you to get a measure of K D and binding affinity. You can also take time ...

  7. Protein mass spectrometry - Wikipedia

    en.wikipedia.org/wiki/Protein_mass_spectrometry

    A mass spectrometer used for high throughput protein analysis. Protein mass spectrometry refers to the application of mass spectrometry to the study of proteins.Mass spectrometry is an important method for the accurate mass determination and characterization of proteins, and a variety of methods and instrumentations have been developed for its many uses.

  8. Protein methods - Wikipedia

    en.wikipedia.org/wiki/Protein_methods

    Protein methods are the techniques used to study proteins. There are experimental methods for studying proteins (e.g., for detecting proteins, for isolating and purifying proteins, and for characterizing the structure and function of proteins, [1] often requiring that the protein first be purified). Computational methods typically use computer ...

    where the first contribution, ~, contains the Coulomb-renormalized single-particle energy that is determined by the bandstructure of the solid.The Coulomb renormalization are identical to those that appear in the semiconductor Bloch equations (SBEs), showing that all photon-assisted polarizations are coupled with each other via the unscreened Coulomb-interaction .
