SEOUL (AFP) — South Korean scientists said Monday they had developed new technology to use transistors in devices for quick diagnosis of diseases such as diabetes.

The biosensor technology was developed by a research team at the state-run Korea Advanced Institute of Science and Technology.

"We proved that transistors can be used not only for computers but also for devices that convert biological responses into electrical signals," team leader Choi Yang-Kyu told AFP.

Biosensors detect biological responses or changes and convert them into an electrical signal that can be read. Currently, they are electrochemical or optical.

"But our technology using existing transistors will open the way for the mass production of cheap but highly efficient...
