A mechanosensitive fluorescent probe visualises and quantifies the mechanical stress on bacterial membranes upon contact with a surface. (Nanowerk News) In natural environments, bacteria rarely live ...

That's the idea behind a new method developed by the Funke Lab at Janelia to count the individual molecules contained in a single spot of light detected by a fluorescence microscope—a quantity ...

SIMIP enables high-resolution images rich in both chemical and spatial information. A quantum cascade laser (QCL) excites molecular vibrations while a spatial light modulator (SLM) generates striped ...

ST. LOUIS, MO, August 20, 2025 - A team of expert scientists led by Kirk Czymmek, PhD, director of the Advanced Bioimaging Laboratory at the Donald Danforth Plant Science Center and Heather E.

Biologists are very interested in how proteins, lipids and other compounds are organized and interact in systems. Very few organizational details can be gained by using standard transmission-based ...

Dynamics Author: Howard Goldner During the past few decades, fluorescence spectroscopy has developed into an integral technique in many scientific disciplines. In the life sciences, it is implemented ...

Researchers have developed a super-resolution microscopy method for the rapid differentiation of molecular structures in 3D. LMU researchers have developed a super-resolution microscopy method for the ...

A new microscopy method enables researchers to visualize the activity of the enzymes caspase-3 and alkaline phosphatase in various biological samples (Nat. Methods 2024, DOI: ...

Processes in the human body are shaped by the interaction of various biomolecules, such as proteins and DNA. These processes take place in a range of often just a few nanometers. They can therefore no ...

Three-dimensional (3D) super-resolution microscopy is essential to study the minute structural details of cells and analyze molecular dynamics. Recently, researchers at Ludwig-Maximilians-Universität ...
