Glucose Sensors and Cancer Detection

Electrochemical biosensors detect target molecules by measuring an oxidation-reduction event. That signal changes when a molecule binds to the sensor surface. These sensors helped shape modern biosensing after the first glucose biosensor was invented.

The glucose biosensor is a key example of thi...

Electrochemical biosensors exploit the natural redox properties of many biological processes, such as enzyme catalysis and other binding events. Electrochemical sensors utilize electrodes which are often functionalized with redox active enzymes. When the target molecule is involved in a reaction with the enzyme the gain or loss of electrons is m...
