MIT Technology Review
: Researchers at Stanford University have developed what they call a Foldscope
, or origami-based paper microscope that is inexpensive to make and rugged enough to survive in the field. Constructed from a single sheet of paper, the microscope also requires a tiny lens, a 3V button battery, and an LED, at a total cost of less than a dollar. Manu Prakash and colleagues have demonstrated how their compact device can provide bright-field, dark-field, and fluorescence microscopy, with up to 2000X magnification. They hope to be able to mass-produce it for use in schools and labs all over the world.
