Blood Sugar Detection of Saliva and Tears

Good news for people with diabetes. To measure blood sugar levels, they will not need to stab your finger with a small needle to draw blood. Now, experts are developing a biosensor for detecting blood glucose levels through tears, saliva, and urine.

Test process in a matter of minutes, as blood glucose detection devices with a needle. Jonathan Claussen, researchers at the Naval Research Laboratory of the United States, who led the research, biosensors, said in Purdue University, U.S., said the biosensor has three main parts, namely nanosheet layer made ​​of Grafen, nanoplatinum particles, and the enzyme glucose oxidase (GOD ) to measure blood sugar levels.

If the enzyme GOD replaced, biosensors can be used to detect other medical conditions. If the enzyme GOD replaced with glutemate oxidase, can be used to measure the neurotransmitter glutamate in Parkinson's and Alzheimer's disease. If replaced ethanol oxidase, can be used for measuring alcohol levels through breath.
