Imaging Biological Samples with Optical Microscopy

9.1K
Optical microscopy uses optic principles to provide detailed images of samples. Antonie van Leeuwenhoek designed the first compound optical microscope in the 17th century to visualize blood cells, bacteria, and yeast cells. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes with enhanced magnification and resolution.
In optical microscopy, the specimen to be viewed is placed on a glass slide and clipped on the stage...

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,...

Super-resolution Fluorescence Microscopy01:37

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...

Area of Science:

  • Photonics and optical engineering
  • Materials science
  • Organic electronics

Background:

  • Metasurfaces supporting bound states in the continuum (BIC) are promising for compact, coherent light sources.
  • Previous etch-free metasurfaces were limited to passive designs, hindering active applications.

Purpose of the Study:

  • To demonstrate highly coherent lasing from etch-free metasurfaces.
  • To explore the potential of organic supramolecular materials for active metasurface applications.

Main Methods:

  • Fabrication of etch-free metasurfaces directly patterned onto small-molecule, ionic isolation lattices (SMILES).
  • Characterization of lasing properties, including directionality, linewidth, and temporal coherence.

Main Results:

  • Achieved highly directional lasing (0.2° divergence) from SMILES-based metasurfaces.
  • Observed narrow linewidth (0.04 nm) and significant temporal coherence (20.4 ± 2.4 ps).
  • Demonstrated the viability of SMILES for active metasurface applications.

Conclusions:

  • The combination of high-quality metasurface design and SMILES material properties enables superior organic molecular lasers.
  • This approach offers a promising strategy for realizing advanced active metasurfaces, outperforming solution-processable alternatives.
