A test that can detect hundreds of thousands of different fragments of DNA sequences, proteins or antibodies could be built onto a tiny silicon chip. Researchers say the technology could lead to devices for medical diagnostics or environmental monitoring.

Jack Hu at Stanford University in California and his colleagues created a metamaterial from silicon that can identify gene fragments just 22 nucleotides long within 5 minutes. When a sample is placed on the chip and near-infrared light is shone on one side of the …
