Confocal Fluorescence Microscopy01:16

Confocal Fluorescence Microscopy

15.9K
Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...

Super-resolution Fluorescence Microscopy

12.3K
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...

Three-dimensional imaging techniques are essential in cell biology, allowing researchers to visualize intricate cellular structures with high resolution. Two prominent methods, Differential Interference Contrast Microscopy (DIC) and Confocal Scanning Laser Microscopy (CSLM), provide distinct advantages for imaging live and thick specimens, respectively.Differential Interference Contrast MicroscopyDIC microscopy enhances contrast in transparent, unstained samples by converting phase...

Overview of Electron Microscopy

11.6K
The wavelengths of visible light ultimately limit the maximum theoretical resolution of images created by light microscopes. Most light microscopes can only magnify 1000X, and a few can magnify up to 1500X. Electrons, like electromagnetic radiation, can behave like waves, but with wavelengths of 0.005 nm, they produce significantly greater resolution up to 0.05 nm as compared to 500 nm for visible light. An electron microscope (EM) can create a sharp image that is magnified up to 2,000,000X.

Area of Science:

  • Biophysics
  • Cell Biology
  • Microscopy

Background:

  • Apoptosis involves significant cellular morphological changes.
  • Label-free detection methods are crucial for in vivo diagnostics.
  • Light scattering microscopy offers potential for label-free cellular analysis.

Purpose of the Study:

  • To modify an inverted microscope for high-resolution light scattering experiments.
  • To detect morphological changes in cells during apoptosis using light scattering.
  • To explore the potential of light scattering microscopy for label-free diagnostics.

Main Methods:

  • Modification of an inverted microscope for combined light scattering and imaging microscopy (fluorescence, laser scanning).
  • Utilized Mie scattering simulations to interpret scattering patterns.
  • Applied the technique to 2D cell cultures and 3D multicellular spheroids (3T3 fibroblasts, HeLa 2E8).

Main Results:

  • Detected morphological changes in 3T3 fibroblasts during apoptosis, including the formation of spherical cells (~20 μm diameter).
  • Observed that cell nuclei and cell clusters may influence scattering behavior.
  • Confirmed findings in 3D spheroids, though morphological changes were less discernible in most cases.

Conclusions:

  • Light scattering microscopy, enhanced with high angular resolution, can detect apoptosis-induced morphological changes in cells.
  • The method shows promise for label-free detection of apoptosis.
  • This technique represents a potential advancement towards label-free in vivo diagnostic applications.
