‘Glow-in-the-dark’ proteins could help diagnose viral diseases

Diagnose diseases more quickly and easily

17-Mar-2023 - Despite recent advancements, many highly sensitive diagnostic tests for viral diseases still require complicated techniques to prepare a sample or interpret a result, making them impractical for point-of-care settings or areas with few resources. But now, a team reporting in ACS Central Science ...

Analysis and Detoxification in One Step

A smart chemoenzymatic method detects and removes hazardous phenols

13-Aug-2019 - Many industrial and agriculture processes use chemicals that can be harmful for workers and the ecosystems where they accumulate. Researchers from Thailand have now developed a bioinspired method to detect and detoxify these chemicals in only one step. As they report in the journal Angewandte ...

Bioluminescent sensor causes brain cells to glow in the dark

31-Oct-2016 - The probe, which was developed by a team of Vanderbilt scientists, is a genetically modified form of luciferase, the enzyme that a number of other species including fireflies use to produce light. The scientists created the technique as a new and improved method for tracking the interactions ...

Photoactivable bioluminescent probe

23-Jun-2009 - A group of scientists led by Bengang Xing, at Nanyang Technological University, Singapore, in collaboration with Zhen Cheng and colleagues at Stanford University Medical Centre, California, have developed a photoactivable bioluminescent probe for imaging luciferase activity in live cells. ...

Blue fluorescent RNA: Tag your it!

04-Aug-2008 - An aptamer-dye pair has been developed as a fluorescent tag to monitor the RNA transcription process, by scientists in Japan. Shinsuke Sando, Yasuhiro Aoyama and colleagues from Kyoto University have chosen an RNA aptamer to selectively bind and 'light-up' a modified Hoechst dye. Usually the ...
