Established a biochemical sensor of human emotions

November 2 2007

Scientists from the University of California at Berkeley have developed a method that allows to detect the activity of substances that determine the person's emotions. It will now be possible to more effectively treat depression, and criminologists could find a fundamentally new "lie detectors."

Belongs to the honor of opening the biochemical laboratory of Professor Christopher Chan. At the core created by him and his colleagues is a fluorescent probe fixing activity of the enzyme monoamine oxidase in living cells. This substance is involved in the exchange of several neurotransmitters (substances that are cellular messengers), such as dopamine and serotonin, removing their excess after use.

Doctors have long established that high levels of monoamine oxidase is often associated with depression and its inhibitors have been used successfully to treat depression. Create a sensor composed of amino fluorescent dye. When interacting with the enzyme, the sensors are oxidized, which leads to a change in color of the solution, which is fixed by the new device.
