This is a perfect solution for biology classrooms, especially in schools that often don't have a microscope available for each student. Schmid and her team tested the CellScope at the San Francisco Friends School for a year. The middle schoolers took pictures of objects around them, both with the microscope and without. The images were displayed in real time on the phone's touch screen and were viewed simultaneously by multiple people so the students could talk about them with teachers. The kids even geotagged the photos and set up a map here.
The Fletcher Lab has also developed two other, similar devices to the CellScope - an otoscope (the thing a doctor looks into your ear with) and a dermascope, which can look at skin cells closely. The lab staff originally saw it as a way to get good equipment to developing countries, but Schmid also realized that there was a need in classrooms in the United States, too.
Schmid said the image quality is every bit as good as the typical binocular microscopes, which was important for using them as diagnostic tools in developing nations. It isn't quite practical yet to equip every school with one - the cost for each unit is a few hundred dollars - but that should come down once they are mass-produced.
Microscope Hats Peer Inside Mouse Brains
The CellScope is similar to the Magnifi, a Kickstarter project that raised its funding earlier this year. The difference is the CellScope is designed specifically for microscopy, using additional optics. Magnifi simply aligns the phone's camera over an eyepiece.
