What about control of blood glucose levels without knocking? In a ray of hope for diabetics around the world, researchers have developed a new biochip sensor that can selectively measure concentrations of glucose in a complex fluid such as saliva. A glucose monitoring system using reliable saliva instead of blood would be a significant improvement in the management of diabetes. “We have demonstrated the need to measure glucose concentrations in saliva, typical sensitivity, which are typically 100 times smaller than in blood,” said Domenico Pacifici, assistant professor of engineering at Brown University in Rhode Island based.

‘are now able to do this with very high specificity, which means we can differentiate glucose from the background components of saliva, “he added. The new chip makes using a series of specific chemical reactions combined with interferometry plasmon – a way to detect the chemical signature of the compounds using light the device is sensitive enough to detect differences in glucose concentrations amounting to a few thousand molecules. . in the sampled volume (Read: Why control of their blood glucose levels is important )

Saliva is approximately 99 percent water, but one percent of that water is not present problems. ‘There enzymes, salts and other components that can affect the sensor response. With this device, we have solved the problem of the specificity of our detection scheme, “Pacifici they said. The biochip is made from a piece of a square inch of quartz coated with a thin layer of silver. Engravings in silver are thousands of interferometers nanoscale. – tiny slits with a groove on each side (Read 😕 What instrument should I buy to check my levels of blood glucose at home (see Disease day )

the next step is to begin to test the method on actual human saliva. ultimately, the researchers hope to develop a small, self-contained device that could give diabetics a noninvasive way to control their glucose levels . it could also be used to detect toxins in the air or water or used in the laboratory to control chemical reactions occurring on the surface of the sensor in real time, Pacifici said in an article published in Nanophotonics magazine.
