If you're diabetic, you'll know how frustrating it can be to check your blood glucose levels (even before you get your reading!). Plus, the method of pricking your finger for a reading can lead to other nasty side effects, like possible infections.
Fortunately, your iPhone's camera could be your way out of the finger-pricking mess, with a gadget developed by a team of university researchers. researchers at Northwestern University created an iPhone case that reads nanosensors used to measure ion and molecule concentrations. The sensors are made out of fluorescent polymer beads that take only seconds to make.
The higher the glucose level, the more fluorescent the tattoo will appear on the skin-remember the sensors on the tattoo are fluorescent so will be visable under certain light.
The iPhone case contains a 9-volt battery, a filter that fits over the phone's camera, and three different colored LEDs that produce the different levels of fluorescent light. The LEDs and filter react to outside light and can fade the colors, so the gadget is placed onto the patient's skin at first to prouce a more accurate reading. So, there may not be an app for that yet, but your iPhone certainly can be used for just about every aspect of your life.
