York University chemists have invented a new fluorescence-based method for accurately determining the strength of a range of Lewis acids, which could one day be used to help purify pharmaceutical ...

Conventional fluorescence microscopy provides poor quantitative information of the sample because it only captures fluorescence intensity, which changes frequently and depends on external factors. Now ...

A new method uses fluorescence to detect potentially disease-causing forms of proteins as they unravel due to stress or mutations. A team of researchers from Penn State and the University of ...

Researchers have developed a new method that reveals the unique fluorescence patterns produced by individual cells in mixtures of bacteria, yeast and fungi. They combined confocal microscopy with ...

An international collaboration of researchers developed two new complementary approaches for versatile but precise light intensity measurements in fluorescence imaging systems. Accurate measurements ...

Making mRNA fluorescent without affecting its natural activity The research behind the method has been done in collaboration with chemists and biologists at Chalmers and the biopharmaceuticals company ...

Microscopic droplets fluoresce bright blue with specks of green. Five droplets in this image (two at the top, two near the center, and one near the bottom) fluoresce blue in varying brightness; each ...

Traditional fluorescence microscopy techniques collect only a small amount of the light emitted from a sample at any one time, so a route to improving their efficiency is to capture more of that light ...

Scattered light is often an unwelcome hindrance in imaging operations, but under the correct circumstances it can be put to good use. Along with several other approaches to increasing the resolution ...

The three-dimensional conformation of the DNA-packaging material chromatin influences gene regulation, but so far biologists have only been able to visualize it indirectly. Sequencing-based methods ...
