A new review article in Microchimica Acta finds that smartphone-based optical and spectroscopic sensors show strong potential to decentralize food safety testing across contaminants like pesticides, heavy metals, and pathogens.
Single use of plastic products contributes to a dramatic trash problem worldwide. Since the near-infrared spectrum of every polymer is unique, spectroscopy can be used to identify and sort a large variety of plastics with high specificity. This application note demonstrates the principle of plastic sorting using near-infrared spectroscopy.
