Link 1: Foldscope: Origami based print and fold paper-microscope

We are a research team at Prakash Lab at Stanford University, focused on democratizing science by developing scientific tools that can scale up to match problems in global health and science education. Here we describe Foldscope, a new approach for mass manufacturing of optical microscopes that are printed-and-folded from a single flat sheet of paper, akin to Origami.

New: We are currently looking for beta-testers for Foldscope. We will be choosing 10,000 people who would like to test the microscopes in a variety of settings and help us generate an open source biology/microscopy field manual written by people from all walks of life. See "Ten Thousand Microscopes signup" for details...
...Foldscope is an origami-based print-and-fold optical microscope that can be assembled from a flat sheet of paper. Although it costs less than a dollar in parts, it can provide over 2,000X magnification with sub-micron resolution (800nm), weighs less than two nickels (8.8 g), is small enough to fit in a pocket (70 × 20 × 2 mm3), requires no external power, and can survive being dropped from a 3-story building or stepped on by a person. Its minimalistic, scalable design is inherently application-specific instead of general-purpose gearing towards applications in global health, field based citizen science and K12-science education.
