Cambridge researchers develop $10 chip to analyse food, plastics, and health signals

Researchers from the University of Cambridge have unveiled an affordable optical spectrometer, retailing for about $10. This ingenious tool can accurately identify different materials, covering sectors like food safety and pharmaceuticals, functioning within a near-infrared wavelength of 1,200 to 1,700 nanometers. Designed for stability under harsh conditions, its non-invasive properties could revolutionize biomarker monitoring in healthcare and various industries.
