Here is an opportunity to be among the 10,000 participants to receive a FREE Foldscope microscope kit. Participants from all walks of life are wanted for testing of this microscope.

For a brief overview of Foldscope and its inspirational back story, view “Print your own 50-cent microscope” at http://www.youtube.com/watch?v=pBjIYB5Yk2. This video was published on Standford Medicine’s channel on March 5, 2014. For more information, visit Foldscope.

Foldscope: Microscopy for everyone
We are a research team at PrakashLab 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.
What I would do with a Foldscope
- Hand washing – I would like to highlight the importance of hand washing in a homeschool science class. To do this I want to set my students loose at the Valle Vista library (my beloved second home) to collect samples from patrons of hands. I would follow the testing procedure set up by Steve Spangler at http://www.stevespanglerscience.com/lab/experiments/growing-bacteria.
- Water safety – I would like to study the microbes in water before and after filtration. If you are interested in making your own water filter, visit on my other blog at http://hemetsunshine.wordpress.com/2012/09/03/ceramic-water-filter.
- Solar-cooked foods and solar-canned foods – Food poisoning is the most common concern I hear when I am asked about solar cooking. I have never had an issue with food poisoning, but would not mine studying the bacteria content of foods that are solar-cooked or solar-canned. I built my first solar cooker in 1995, to make a solar cooker like mine or just read about my experiences with solar cooking, visit my other blog at http://hemetsunshine.wordpress.com/2011/07/03/a-box-cooker-without-reflectors.

- http://arxiv.org/abs/1403.1211 – Foldscope: Origami-based paper microscope
- by James Cybulski, James Clements, Manu Prakash – Submitted on 5 Mar 2014 – “Here we describe an ultra-low-cost origami-based approach for large-scale manufacturing of microscopes, specifically demonstrating brightfield, darkfield, and fluorescence microscopes. Merging principles of optical design with origami enables high-volume fabrication of microscopes from 2D media. Flexure mechanisms created via folding enable a flat compact design. Structural loops in folded paper provide kinematic constraints as a means for passive self-alignment. This light, rugged instrument can survive harsh field conditions while providing a diversity of imaging capabilities, thus serving wide-ranging applications for cost-effective, portable microscopes in science and education.”
