Bioengineer builds 50-cent paper microscope


Stanford bioengineer Manu Prakash devised a pretty amazing paper microscope that uses cheap tiny spherical lenses. The "Foldoscope" costs around 50 cents.


"I wanted to make the best possible disease-detection instrument that we could almost distribute for free," Prakash says. "What came out of this project is what we call use-and-throw microscopy."
