Researchers boost accuracy of home-based continuous glucose monitoring

Home-based continuous glucose monitoring for diabetics up to now has had to trade ease of use, low cost, and portability for a somewhat lower sensitivity—and thus accuracy—compared to similar systems in clinics or hospitals. A team of researchers has now developed a biosensor for such monitors that involves "zero-dimensional" quantum dots (QDs) and gold nanospheres (AuNSs), and no longer has to compromise on accuracy.
