Biosensors Flashcards
Where can a biosensor be used?
Can be used anywhere that a biological molecule, such as an enzyme or antibody can be used.
Eg, in cells and tissue.
How does a glucose biosensor work?
It uses the enzyme glucose oxidase to convert glucose into gluconolactone, using a variety of mediators to induce a flow of electrons and thus a measurable current.
A glucose biosensor can be used to diabetes to….
Measure blood glucose levels.
What is a biosensor?
An analytical device for detection of an analyte, consisting of a biological component and a detector and a reading device.
A glucose biosensor is….
An electrochemical sensor.
A disadvantage of a second generation glucose biosensor….
Requires high voltage which can lead to oxidation of other compounds and result in false readings.
