Smart Sensor for Testing Agrifood Quality & Safety at the Point of Care

The Device we present is a Lab-on-Chip. It consists of a system on glass (SoG), where are integrated photosensors for light detection, a thermalization system and sensors for controlling the temperature. The SoG is coupled with a microfluidic system where biological assay occurs and allows the detection of mycotoxins and food pathogens. The system is contained in a portable metallic box. The assays consist of specific recognition elements for the detection of the mycotoxins, which identify the target (mycotoxins) and emits a luminescent signal when the target is present. The luminescent signal is then detected by the photosensors. In the case of food pathogens, the system is able to perform a molecular test: identify a specific DNA sequence of the pathogens, which is amplified and detected by the photosensors following the luminescent signal generated during the DNA amplification. The thermalization system ensures the reactions occurring at the requested temperature.
