New Biosensor with Dual-Mode Fluorescence and Electrochemistry
Recently, researchers from the Suzhou Institute of Biomedical Engineering and Technology (SIBET) of the Chinese Academy of Sciences proposed a technique for hand-in-hand structured DNA construction.

The new sensor, according to the researchers, combines features of electrochemical and fluorescence sensors, whose signal sources and manufacturing processes are normally highly different. An electrochemical sensor is a qualitative or quantitative method based on the correlation between concentration or other physical properties and the electrical signal change produced by the target. A fluorescence sensor is a device that uses a specific target and recognition combina...
