These color-enhanced scanning electron microscope images show nanosheets resembling tiny rose petals. The nanosheets are key components of a new type of biosensor that can detect minute concentrations ...

University researchers are experimenting with using tears, instead of blood, to calculate glucose levels for diabetics. Chemistry Prof. Mark Meyerhoff was among several University scientists working ...

For diabetics, there is no comfortable way to accurately measure blood sugar that does not involve blood. Testing takes a little pinprick, but some people who should test many times a day don't ...

Google is testing prototypes of a “smart” contact lens that will make it easier for diabetes patients to monitor their blood sugar levels and stay healthy. Project leaders Brian Otis and Babak Parviz ...

(Nanowerk Spotlight) Diabetes affects millions of people worldwide, requiring constant monitoring of blood glucose levels to manage the disease and avoid complications. Typically, this involves ...

A team of South Korean researchers are the latest to tout a smart, glucose-sensing contact lens. In a research article published today in Science Advances, the team described soft lenses carrying a ...

In a small but revealing study, scientists discovered that tears strongly mirror blood glucose and saliva may reflect vitamin D status. This could lead to less invasive ways to monitor chronic health.

U.S. researchers have created a new type of biosensor that can detect minute concentrations of glucose in saliva, tears, and urine, and might be manufactured at low cost because it does not require ...
