Researchers at the University of Illinois Urbana-Champaign have created a cradle device and an app that can turn a smartphone into a handheld biosensor.
The smartphone can identify environmental toxins, blood tests, water and crop contamination, and allergens in food, such as traces of peanuts in a cookie, notes the Daily Mail.
By working together, the cradle, app and cell phone serve as a portable mini-science lab (video below).
"Take an off-the-shelf iPhone and, using some minor modifications, we can take the onboard camera and we're able to make a smartphone even smarter," researcher Kenny Long told the Associated Press.
"We can diagnose disease, We can look for crop contamination. We can look at water contamination, all sorts of different things."
