High-resolution transmission electron microscopy is an imaging mode of specialized transmission electron microscopes that allows for direct imaging of the atomic structure of samples. [ 1 ] [ 2 ] It is a powerful tool to study properties of materials on the atomic scale, such as semiconductors, metals, nanoparticles and sp 2 -bonded carbon (e.g ...
High Resolution Melt (HRM) analysis is a powerful technique in molecular biology for the detection of mutations, polymorphisms and epigenetic differences in double-stranded DNA samples. It was discovered and developed by Idaho Technology and the University of Utah. [1] It has advantages over other genotyping technologies, namely:
High-resolution scanning transmission electron microscopes require exceptionally stable room environments. In order to obtain atomic resolution images in STEM, the level of vibration, temperature fluctuations, electromagnetic waves, and acoustic waves must be limited in the room housing the microscope.

Fluorescence and confocal microscopes operating principle. Confocal microscopy, most frequently confocal laser scanning microscopy (CLSM) or laser scanning confocal microscopy (LSCM), is an optical imaging technique for increasing optical resolution and contrast of a micrograph by means of using a spatial pinhole to block out-of-focus light in image formation. [1]
The standard resolution of the images is usually 512×512 or 720×576. Most of these images are available as TIFF files from the University of Southern California's Signal and Image Processing Institute. [1]
Light sheet fluorescence microscopy (LSFM) is a fluorescence microscopy technique with an intermediate-to-high [1] optical resolution, but good optical sectioning capabilities and high speed. In contrast to epifluorescence microscopy only a thin slice (usually a few hundred nanometers to a few micrometers) of the sample is illuminated ...
Susie Coughlin was concerned when her daughter struggled with reading skills at her public school.. The mom of two was disappointed her district didn't teach phonics as part of its literacy program.
According to Proteopedia, the median resolution achieved by X-ray crystallography (as of May 19, 2019) on the Protein Data Bank is 2.05 Å, [17] and the highest resolution achieved on record (as of September 30, 2022) is 0.48 Å. [22] As of 2020, the majority of the protein structures determined by cryo-EM are at a lower resolution of 3–4 Å ...
