Cell number and viability matter from biological research to bioprocessing. So, scientists keep working on better ways to monitor these features of cell cultures. One promising approach comes from ...

(Nanowerk News) University of Groningen scientists have developed a molecular sensor to measure 'crowding' in cells, which reflects the concentration of macromolecules present. The sensor provides ...

The next time you reach for a memory or make a quick choice, a storm of tiny signals races through your brain. Scientists can ...

Biological sensors are crucial to survival. Like eyes and ears, they help us process the world and protect us from danger. On a smaller scale, biological sensors such as nerves send signals to the ...

Wearable health devices, such as smartwatches, have become commonplace, enabling the continuous monitoring of physiological ...

The ability to explore cell signalling and cell-to-cell communication is essential for understanding cell biology and developing effective therapeutics. However, it is not yet possible to monitor the ...

For the first time, engineers have demonstrated an electronic device to closely monitor beating heart cells without affecting their behavior. A collaboration between the University of Tokyo, Tokyo ...

A fluorescent biosensor is the first to quantify the ionic strength inside living cells (ACS Chem. Biol. 2017, DOI: 10.1021/acschembio.7b00348). The sensor could enable cell biologists to follow ...

Scientists have developed a molecular sensor to measure 'crowding' in cells, which reflects the concentration of macromolecules present. The sensor provides quantitative information on the ...
