Frequency-domain STED microscopy for selective background noise suppression

Novel method suppresses background noise in STED microscopy selectively and effectively, with potential for integration into other dual-beam point-scanning techniques

08-Jul-2022

Nanoscopy describes the ability to see beyond the generally accepted optical limit of 200–300 nm. Stimulated emission depletion (STED) microscopy, developed by Stefan W. Hell and Jan Wichmann in 1994, and experimentally demonstrated by Hell and Thomas Klar in 1999, is a superresolution technique ...

Microscopy technique enables 3D super-resolution nanometre-scale imaging

Research team combine two techniques to achieve isotropic super-resolution imaging

24-Jun-2022

Over the last two decades, microscopy has seen unprecedented advances in speed and resolution. However, cellular structures are essentially three-dimensional, and conventional super-resolution techniques often lack the necessary resolution in all three directions to capture details at a nanometer ...

Primates and non-primates differ in the architecture of their neurons

Various mammalian species and high-resolution microscopy reveal the variable axonal origin

08-Jun-2022

High-resolution microscopy now enabled an international research team to enlarge the knowledge about species-specific differences of the architecture of cortical neurons. Researchers from the research group Developmental Neurobiology at Ruhr-Universität Bochum around Professor Petra Wahle, in ...

Sharp X-ray images despite imperfect lenses

New method for X-ray microscopy

03-Jun-2022

X-rays make it possible to explore inside human bodies or peer inside objects. The technology used to illuminating the detail in microscopically small structures is the same as that used in familiar situations – such as medical imaging at a clinic or luggage control at the airport. X-ray ...

A sharper image for proteins

New technique promises to revolutionize the imaging of proteins and other vital biomolecules

05-May-2022

Proteins may be the most important and varied biomolecules within living systems. These strings of amino acids, assuming complex 3-dimensional forms, are essential for the growth and maintenance of tissue, the initiation of thousands of biochemical reactions, and the protection of the body from ...

analytica 2022: Analytics that benefit consumer and environmental protection

Does your mineral water contain nanoplastics or other pollutants?

28-Apr-2022

Is that asparagus really local? Has the honey been diluted with cheap sugar? “analytica provides food inspectors with all the tools they need to answer these questions quickly and reliably,” says Armin Wittmann, analytica Exhibition director at Messe München. At the world's leading trade fair for ...
