Manu Prakash, an assistant professor of bioengineering at Stanford’s School of Medicine, along with his colleagues, has designed what they are calling a “foldscope” or origami paper microscope. The foldscope is printed onto a sheet of card stock with an optical lense, LED light, and watch battery embedded in the layout. Produced for about fifty cents each, the flat printed sheet easily folds into a working three-dimensional microscope with up to 2000 times magnification. This could be a real game-changer in developing countries trying to improve health by identifying disease pathogens. The paper microsope is lightweight and very durable–perfect under harsh field conditions. To learn more, watch Mr. Prakash’s TED talk. Thank you to Leslie Wright and Paulette Rosen for bringing this to our attention!
