Electron Microscope Tomography and Single-particle Reconstruction

2.7K
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.
Electron Tomography
Electron tomography can be performed either in TEM or STEM (scanning transmission...

Atomic Force Microscopy01:08

Atomic Force Microscopy

4.0K
Atomic force microscopy (AFM) is a type of scanning probe microscopy that can analyze topographic details of various specimens like ceramics, glass, polymers, and biological samples. AFM offers over 1000 times more resolution than the optical imaging system. Images generated from AFM are three-dimensional surface profiles, offering an advantage over the flat, two-dimensional images from other imaging techniques.
The AFM Probe
The probe is regarded as the heart of any AFM setup and comprises the...

Three-Dimensional Microscopy in Microbiology

656
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...

Total Internal Reflection Fluorescence Microscopy01:05

Total Internal Reflection Fluorescence Microscopy

10.9K
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.

Area of Science:

  • Biomedical Optics
  • Microscopy
  • 3D Imaging

Background:

  • Conventional microscopy often requires physical scanning for 3D data acquisition, limiting speed and introducing inertia.
  • Achieving high-resolution volumetric imaging in biological specimens presents significant challenges.

Purpose of the Study:

  • To introduce Airy-beam tomographic microscopy (ATM) for high-resolution, volumetric, and inertia-free 3D imaging.
  • To demonstrate the capability of ATM in overcoming limitations of conventional scanning microscopy.

Main Methods:

  • Utilizing highly adjustable Airy trajectories in 3D space.
  • Transforming conventional telecentric wide-field imaging schemes.
  • Eliminating the need for sample or focal-plane scanning.

Main Results:

  • Consistent near-diffraction-limited 3D resolution was achieved.
  • Imaging depth was extended tenfold compared to wide-field microscopy.
  • Demonstrated inertia-free volumetric imaging of biological specimens.

Conclusions:

  • Airy-beam tomographic microscopy (ATM) offers a promising new paradigm for 3D optical microscopy.
  • The ATM strategy has potential for translation to other non-optical waveform imaging.
  • ATM enables high-resolution, extended-depth, and rapid 3D imaging without mechanical scanning.
