Make no mistake, microscopes have been getting increasingly smaller for years, but a team of CalTech researchers have leapfrogged previous efforts by creating one minuscule enough to fit on a cellphone. The microscopic optofluidic microscope could one day be used in third-world nations to "analyze blood samples for malaria or check water supplies for giardia and other pathogens," and given that it could theoretically be mass produced for around $10, cost shouldn't be too much of a hindrance. Changhuei Yang, credited for developing the chip, is currently chatting it up with biotech companies in order to get this to the market, but there's no word yet on any takers.
