Self-driven disposable sensor for easy measurement of blood glucose levels at home

Electrochemical biosensors utilize biomolecules, such as enzymes and antibodies, as bioreceptors that recognize specific substances in a sample. This recognition generates an electrical signal that provides information about what is present and in what quantity. For instance, to determine the concentration of glucose in the blood, an electrochemical sensor with an enzyme that selectively recognizes glucose is used. However, this type of sensor usually requires a dedicated electrode and a device to control the reaction that takes place at the electrode.
