Super-resolution Fluorescence Microscopy01:37

Super-resolution Fluorescence Microscopy

9.4K
Super-resolution fluorescence microscopy (SRFM) provides a better resolution than conventional fluorescence microscopy by reducing the point spread function (PSF). PSF is the light intensity distribution from a point that causes it to appear blurred. Due to PSF, each fluorescing point appears bigger than its actual size, and it is the PSF interference of nearby fluorophores that causes the blurred image. Various approaches to achieving higher resolution through SRFM have recently been...

Electron Microscope Tomography and Single-particle Reconstruction

2.6K
Transmission electron microscopy (TEM) can be used to determine the 3D structure of biological samples with the help of techniques such as electron microscope tomography and single-particle reconstruction. While single-particle reconstruction can examine macromolecules and macromolecular complexes in vitro conditions only, tomography permits the study of cell components or small cells in vivo.

Total Internal Reflection Fluorescence Microscopy01:05

Total Internal Reflection Fluorescence Microscopy

8.4K
Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.

Protein Dynamics in Living Cells

2.4K
Different fluorescence-based techniques are used to study the protein dynamics in living cells. These techniques include FRAP, FRET, and PET.
Fluorescent recovery after photobleaching (FRAP) is a fluorescent-protein-based detection technique used to quantify protein movement rates within the cell. This method exposes a small portion of the cell to an intense laser beam. The laser beam causes permanent photobleaching of the fluorophore-tagged proteins in the exposed region. As the bleached...

Area of Science:

  • Biophysics
  • Optical Imaging
  • 3D Reconstruction

Background:

  • Optical diffraction tomography (ODT) is crucial for 3D object analysis.
  • Traditional ODT requires coherent light due to the need for spatial phase information to solve the inverse scattering problem.

Purpose of the Study:

  • To extend ODT capabilities to incoherent contrast mechanisms, specifically fluorescent emission.
  • To enable 3D imaging of fluorescent objects using a novel ODT approach.

Main Methods:

  • Developed a method mimicking coherent scattering using two spatially coherent illumination beams.
  • Encoded spatial phase information into temporal variations of fluorescent emission.
  • Utilized an inverse scattering model to reconstruct the 3D spatial distribution of fluorescent emission.

Main Results:

  • Successfully demonstrated the ability to apply ODT to incoherent fluorescent emission.
  • Achieved isotropic resolution in the 3D reconstruction of fluorescent objects.
  • Validated the method through both simulations and experimental results.

Conclusions:

  • The novel ODT method effectively images incoherent contrast mechanisms like fluorescence.
  • This technique overcomes previous limitations of ODT, expanding its applicability in 3D imaging.
  • The approach allows for high-resolution 3D reconstruction of fluorescent samples.
