Biochip developed to measure blood sugar via saliva
A new biochip sensor that can selectively measure glucose concentrations in a complex fluid like saliva has been developed by scientists at Brown University in the US. It is an important breakthrough towards developing a device that would enable people with diabetes to check their glucose levels without drawing blood.
Developers of the device have used a series of specific chemical reactions combined with plasmonic interferometry, a means of detecting chemical signature of compounds using light. The device is sensitive enough to sense variations in glucose concentrations that amount to just a few thousand molecules in the sampled volume.
