Blood glucose monitoring is the use of a glucose meter for testing the concentration of glucose in the blood ().Particularly important in diabetes management, a blood glucose test is typically performed by piercing the skin (typically, via fingerstick) to draw blood, then applying the blood to a chemically active disposable 'test-strip'.
Fluorescent glucose biosensors are devices that measure the concentration of glucose in diabetic patients by means of sensitive protein that relays the concentration by means of fluorescence, an alternative to amperometric sension of glucose. Due to the prevalence of diabetes, it is the prime drive in the construction of fluorescent biosensors.
A glucose meter, also referred to as a "glucometer", [1] is a medical device for determining the approximate concentration of glucose in the blood.It can also be a strip of glucose paper dipped into a substance and measured to the glucose chart.
The Dexcom Stelo Glucose Biosensor System will be available this summer and is intended for anyone 18 years and older who does not use insulin. This would include individuals with diabetes using ...
A continuous glucose monitor (CGM) is a device used for monitoring blood glucose on a continual basis instead of monitoring glucose levels periodically by drawing a drop of blood from a finger. This is known as continuous glucose monitoring .
The sensor uses a bioreceptor and transducer as outlined above. An example of an in vitro biosensor is an enzyme-conductimetric biosensor for blood glucose monitoring. There is a challenge to create a biosensor that operates by the principle of point-of-care testing, i.e. at the location where the test is needed.

The Clark oxygen electrode laid the basis for the first glucose biosensor (in fact the first biosensor of any type), invented by Clark and Lyons in 1962. [6] This sensor used a single Clark oxygen electrode coupled with a counter-electrode. As with the Clark electrode, a permselective membrane covers the Pt electrode.
