In their first study, the team showcased the utility of the biosensor for monitoring glutamate levels by demonstrating selective activation by glutamate in cell cultures. By conducting experiments ...

Next, the researchers tested the biosensors in vivo by administering the bacteria via enema to three groups: mice without tumors, mice with normal colorectal tumors, and mice with the engineered ...

The department’s biosensors and biomedical instrumentation research focuses on the development ... this interaction can be used for developing novel ways to image physiological processes and ...

Over time, the mice learned to stop escaping from the black spots. Based on previous work in the Hofer Lab, the team knew that an area of the brain called the ventrolateral geniculate nucleus ...

“For our innovation, we used organic polymer materials that are inherently closer to us biologically, and we designed it to interact with ions, because the language of the brain and body is ...

In 2021, the Janelia group leaders reported that they had developed a way to combine Schreiter's engineered protein biosensors and ... zebrafish, and mice. The new technique can also be used ...

Columbia scientists studying mice have identified specialized neurons that respond to a variety of cues to then instruct the animals to stop eating. Though many feeding circuits in the brain are ...
