Biosensor is used to measure

A. Blood glucose level
B. The body pH value
C. Amount of hemoglobin
D. Salinity in Urine
E. None of above

Check Answer

The correct answer is A) Blood glucose level.

A biosensor is a device that uses biological components, such as enzymes or antibodies, to detect and measure specific substances in a sample. One of the most common use of biosensors is for measuring the level of glucose in blood, particularly in people with diabetes. These biosensors typically consist of a small, handheld device that uses a small drop of blood to measure the glucose level.

The blood glucose biosensor work by utilizing enzymes such as Glucose oxidase or Hexokinase, which converts glucose into hydrogen peroxide. The change in the hydrogen peroxide concentration can then be used to determine the glucose level. These biosensors are non-invasive, easy to use and give results faster than the traditional methods, which makes it a popular way to monitor glucose level in people with diabetes.
