Simple, Low-Tech Disease Diagnostics (IMAGE) Emory Health Sciences Caption Emory post-doctoral fellow Kevin Yehl sets up a smart-phone microscope to get a readout for the particle motion of the rolling DNA motor. This simple, low-tech method could come in handy for doing disease diagnostics in the field, for instance, detecting a single mutation in a DNA strand.
