Development of a FRET sensor for real-time imaging of intracellular redox dynamics

A multidisciplinary research team within the Institute for Genomic Biology at the University of Illinois, Urbana-Champaign reports a FRET-based biosensor with defined sensitivity and dynamic range for imaging changes in the intracellular redox environment that appear to dictate cell fate. The FRET-based biosensors are a significant advance for routinely measuring oxidative stress in real-time. The sensor is most useful for monitoring intraorganellar glutathione potentials in the relatively high oxidative environments of ER, Golgi and lysosomes.

Researchers produce high-quality graphene with a single step

Graphene is the electronic miracle material of the 21st century. Until now, only sheets that were very small or of a somewhat inferior quality could be produced that were too small or not well suited for high-tech applications. Now, researchers have developed a process capable of producing a high-quality product with a single step.

New chemical method paves the way for making a greater variety of light-sensitive materials that was not possible before

Scientists from Singapore's Institute of Materials Research and Engineering (IMRE) and National University of Singapore (NUS) have created a new chemical method that enables the development of a variety of tiny light conducting metal-semiconductor contacts. These light-sensitive nano-sized components could help create bioimaging labels as well as better photocatalysts used in fuel cells.
