A molecular sensor for in-situ analysis of complex biological fluids

A research group presented a molecular sensor with a microbead format for the rapid in-situ detection of harmful molecules in biological fluids or foods. As the sensor is designed to selectively concentrate charged small molecules and amplify the Raman signal, no time-consuming pretreatment of samples is required. https://www.sciencedaily.com/releases/2018/10/181023110543.htm
