Foldscope: The Paper Microscope

Microscopes are crucial for diagnosing infectious disease. But in some ways they’re the worst possible device—heavy, expensive, and hard to maintain. Paper microscopes, also known as foldscopes, contain all the crucial parts within one foldable sheet of paper. They can be optimized for different diseases and cost less than a dollar.
