Total Internal Reflection Fluorescence Microscopy

Total Internal Reflection Fluorescence Microscopy

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.

Transmission Electron Microscopy

Transmission Electron Microscopy

In 1931, physicist Ernst Ruska—building on the idea that magnetic fields can direct an electron beam just as lenses can direct a beam of light in an optical microscope—developed the first prototype of the electron microscope. This development led to the development of the field of electron microscopy. In the transmission electron microscope (TEM), electrons are produced by a hot tungsten element and accelerated by a potential difference in an electron gun, which gives them up to 400...

Electron Microscope Tomography and Single-particle Reconstruction

Electron Microscope Tomography and Single-particle Reconstruction

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...

Overview of Microscopy Techniques

Overview of Microscopy Techniques

The early pioneers of microscopy opened a window into the invisible world of microorganisms. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes that leveraged nonvisible light, such as fluorescence microscopy that uses an ultraviolet light source and electron microscopy that uses short-wavelength electron beams. These advances significantly improved magnification, image resolution, and contrast. By comparison, the...

Background:

Near-field scanning optical microscopy (NSOM) offers sub-diffraction limit resolution by probing near-field interactions.
Standard NSOM relies on external illumination across various spectra (visible to gigahertz).
NSOM is effective for studying surface waves like plasmons and phonon polaritons.

Purpose of the Study:

To develop an infrared NSOM operating without external illumination.
To introduce a novel instrument termed the 'thermal radiation scanning tunnelling microscope' (TRSTM).
To demonstrate TRSTM's capability in imaging thermal emission and surface phenomena.

Main Methods:

Development of an infrared NSOM system.
Utilizing thermally emitted infrared evanescent fields from the sample surface.
Operating the instrument as an optical scanning tunnelling microscope analogue.

Main Results:

Acquisition of the first TRSTM images.
Visualization of thermally excited surface plasmons.
Demonstration of spatial coherence effects in near-field thermal emission.

Conclusions:

TRSTM functions as a near-field analogue to a night-vision camera, imaging thermal radiation.
The instrument provides a new method for studying surface phenomena driven by thermal emission.
TRSTM opens avenues for investigating nanoscale thermal transport and emission properties.
