For diseases like tuberculosis and cancer, there is no one-size-fits-all treatment. The most effective regimen will depend on the disease’s DNA: Genetic sequences can reveal whether a TB infection is resistant to certain antibiotics, or whether a tumor has mutations that render some drugs useless.

To unravel these sequences, physicians must ship patients’ samples to independent laboratories for testing—an inconvenient, time-consuming, and expensive process. But a new device, which enables a phone to detect mutations in a cell’s DNA, may let doctors bypass the hassle.

Don’t mistake this machine for a smartphone case. Its 3D-printed exterior contains two lasers, a white LED, a lens, and a filter that turn your smartphone’s camera into a molecular microscope.
