Modern bioassays tend to fall under three common modalities: colorimetric, luminometric or fluorometric. Colorimetric assays record the amount of light absorbed by a reporter compound. This absorbance ...

Scientists have introduced a microscopy technique that reveals a hidden layer of chemistry involving molecules that normally ...

A team of US researchers has gained new insights into how large protein molecules consistently fold themselves into useful shapes. Using a new approach to fluorescence microscopy, Hoi Sung Chung and ...

Fluorescent anatomy, which recently seemed to be a quirk in unusual animals such as platypuses and opossums, was found in most living families of mammals. By Cara Giaimo At first, it seemed to be ...

Shining a beam of light into potentially contaminated water samples may hold the key to real-time detection of hydrocarbons and pesticides in water. Researchers are testing the use of fluorescence to ...

Researchers present a novel ion-trap chip integrating photonics for efficient fluorescence photon collection, enhancing ...

Flow cytometry detects and measures the chemical and physical properties and characteristics of particles or cells within a population. Samples are suspended in a liquid, held in a tube, and counted ...
