emdt.co.uk European Medical Device Technology Spring 2014 | 17 $1 Microscope to Fight Malaria A new microscope made out of paper could bring help to millions of Malaria patients around the world. Manu Prakash led a team at Stanford University that developed a method to fold a working microscope using Origami techniques. Material costs of the device are below one U.S. dollar. "Just for malaria itself, there are a million deaths a year, and more than a billion people that need to be tested because they are at risk for different species of malarian infections," says Prakash. The research team thought that microscopes that are currently used to diagnose the disease were unsuitable for the conditions of many emerging countries. "The problem lies with the microscope itself. Even though the pinnacle of modern sci- ence, research microscopes are not designed for field testing. Neither were they first designed for diagnostic. They are heavy, bulky, really hard to maintain and cost a lot of money," accord- ing to Prakash. In addition to being cheap, the Origami microscopes are very easy to transport because they are made of paper. It is even pos- sible to send several microscopes in one envelope. To prove how rugged the device is, Prakash threw the microscope on the flow and stomped on it during a TED talk. To set up the microscope, no instructions are needed, according to Prakash. An embedded color code printed on the surface of the paper explains how to fold it. The Foldscope can be assembled within 10 minutes with a sheet of paper, a small lens (56 US Cent) and a 3-V battery (6 US Cent). Because the goal was to reduce complexity as much as possible, each microscope has only one imaging capability. "The versions we have go all the way from bright field stan- dard microscopes to fluorescent, to dark field polarization and an unusual one, which we call projection microscope, in which you just literally project the image to a wall." Depending on the application, the different versions have varying magnifications and corresponding resolutions. —T.K.
