Development of a device to project trace gas from the skin Tokyo Medical and Dental University December 25, 14:02
A research group at Tokyo Medical and Dental University has developed a special device that detects an extremely small amount of gas emitted from the skin and projects it on the screen. It can be seen in real time that some of the components in the blood are released as gas, which could be used for detecting alcohol and early detection of diabetes, cancer, etc.
The device was developed by a research group of Professor Koji Mibayashi of Tokyo Medical and Dental University.
Focusing on the fact that some components in blood volatilize and are released from the skin as extremely small amounts of gas, the group has developed a sensor that uses a special enzyme that binds to small amounts of gas.
When the sensor detects the gas, it reacts to the ultraviolet light emitted from the LED and shines in blue etc.It detects the small amount of gas coming out of the palm of the person who actually drank alcohol and displays it on the screen in real time That's it.
The group says that the device could be used to detect trace amounts of substances released from the skin of patients with diabetes and some cancers, and could be used for early detection of disease.
Professor Mibayashi says, "It is possible that a simple test, such as holding your hand, can detect a disease early. We would like to increase the sensitivity so that even the smallest gas can be detected accurately." .
