"50 to 100 times quicker than existing technologies... uses laser light to detect chemical or biological analytes. Called a plasmo-photonic bimodal multiplexing sensor, the system can spot bacteria or pesticides label-free, without having to use chemicals or dyes as a marker... Everything is done on a single chip – we are working to detect seven different analytes simultaneously"
