Researchers at the University of Illinois are making smartphones even smarter in the medical field.
UI Professor Brian Cunningham and his team of engineers have made a sensor and app for the iPhone that can be used to detect things like bacteria, cells and viruses.
Cunningham said this will help researchers and scientists when they have to travel to remote places. Rather than taking samples back to a lab, things can be tested right then and there.
He added that this will especially benefit places that cannot afford high-tech medical facilities.
