Quantum physics and origami for the ultimate get-well card

The bizarre optical properties of tiny metal particles -- smaller than light waves -- can be captured on paper to detect even a single target molecule in a test sample. These hyper-sensitive testing devices could be assembled and customized at the point of use in low-resource environments, with virtually limitless applications spanning medicine, forensics, manufacturing and environmental safety.
