A new medical-diagnostic device made out of paper detects biomarkers and identifies diseases by performing electrochemical analyses - powered only by the user’s touch - and reads out the color-coded test results, making it easy for non-experts to understand.

The self-powered, paper-based electrochemical devices, or SPEDs, are designed for sensitive diagnostics at the “point-of-care,” or when care is delivered to patients, in regions where the public has limited access to resources or sophisticated medical equipment.
