New Technology Allows Diabetes Testing Through Saliva and Tears

This Research inِ Action article wasِ providedِ to LiveScience inِ partnership withِ theِ National Science Foundation.
These color-enhanced scanning electron microscope images show nanosheets thatِ areِ components ofِ a newِ biosensor thatِ canِ detect evenِ minute concentrations ofِ glucose inِ fourِ differentِ human serums: saliva, tears andِ urine asِ well asِ blood.
The biosensor mightِ one day beِ a welcomeِ relief toِ diabetics whoِ haveِ to regularly prick theirِ fingers toِ test theirِ sugar levels.
