Scientists use iPhone microscope to diagnose intestinal worms
The last big growth opportunity for mobile devices is in the medical field. Mobile is already a powerhouse for communication, entertainment, and as an information hub, but the work is still in progress to make medical devices more mobile. We've seen theoretical work, but this story is a pretty impressive practical application, because scientists were able to use a hacked-together iPhone microscope to diagnose intestinal worms in Pemba Island, off the coast of Tanzania.
The scientists converted the iPhone into a microscope by putting double-sided tape over the camera lens, then piercing a hole in the tape and placing a small $9 lens over the existing camera lens. The flashlight was used for illumination, the double-sided tape held the stool sample slides in place, and the image on the phone's screen was studied for intestinal parasites. It isn't a perfect system, but it was able to diagnose 70% of the infections compared to a conventional laboratory microscope. In many cases that may just be good enough, but more importantly, it is a very inexpensive option.
