Here is a good news for diabetics. Those painful daily pinpricks will be over soon. A new device has been developed that ‘interestingly’ uses teardrops for measuring the amount of sugar in a person’s blood. Yes, it’s teardrop.
According to the project leader Florencio Hernandez of the University of Central Florida, the test involves a gold-salt solution, which on getting exposed to sugar - glucose — generates detectable gold nano-particles. Though the source of the glucose can be a person’s blood or urine too, tears is considered to be the most effective.
