A novel portable technology that employs fluorescence and Surface Plasmon Resonance (SPR) to identify the presence of pesticides, heavy metals, and bacteria in liquid foods with short supply chains, such as honey, raw milk, and beer. After 42 months, the European research project "h-ALO (Photonic System for Adaptable Multiple-Analyte Monitoring of Food Quality)" has been successfully concluded. The project was initiated by the Institute for the Study of Nanostructured Materials of the National Research Council of Bologna (Cnr-Ismn) and Warrant Hub (Tinexta Group), one of the primary European operators in strategic and financial consulting for innovation, digital revolution and company sustainability. The European Commission financed the project with a budget of more than 4.2 million euros through the Horizon 2020 program. The technique developed by h-ALO researchers is simple, can be used by non-specialists, and provides accurate and trustworthy findings for a wide range of liquid substances. It also includes technologies that have been developed to simplify field testing, an integrated microprocessor for fluorescent detection, and the capacity to simultaneously detect various types of pesticides.
