Confocal Fluorescence Microscopy01:16

Confocal Fluorescence Microscopy

16.0K
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,...

Scanning Electron Microscopy

5.1K
A scanning electron microscope (SEM) is used to study the surface features of a sample by using an electron beam that scans the sample surface in a two-dimensional manner. Typically, areas between ~1 centimeter to 5 micrometers in width can be imaged. SEM can be used to image bacteria, viruses, tissues as well as larger samples like insects. Conventional SEM gives a magnification ranging from 20X to 30,000X and spatial resolution of 50 to 100 nanometers.

Raman Spectroscopy: Overview

2.6K
The underlying principle of Raman spectroscopy is based on the interaction between light and matter, specifically molecules' inelastic scattering of photons. When a monochromatic beam of light, typically from a laser source, interacts with a sample, most scattered light has the same frequency as the incident light. This is known as Rayleigh scattering.
However, a small fraction of the scattered light exhibits a frequency shift due to the exchange of energy between the incident photons and...

Area of Science:

  • Biomedical Optics
  • Medical Imaging
  • Tissue Microscopy

Background:

  • Elastic light scattering is sensitive to ultrastructural changes.
  • Bulk tissue imaging is limited by absorption and multiple scattering, reducing contrast.

  • Utilizing structured high spatial frequency illumination and detection.
  • Probing tissue with structured light to obtain scattering response maps.
  • Employing SLS to achieve absorption-independent imaging.

Main Results:

  • SLS generates direct, high-resolution maps of tissue scattering response.
  • The method is independent of molecular absorption effects.
  • Scattering response is tunable with wavelength and spatial frequency, enabling multiscale analysis.

Conclusions:

  • SLS offers a powerful new tool for imaging superficial tissue layers.
  • The technique provides absorption-independent, high-resolution morphological information.
  • SLS methodology is adaptable to existing wide-field imaging systems.
