Portable single unit device for Ochratoxin A (OTA) toxicity analysis for rice quality monitoring

A fluorescent detector device comprising:

• a display interface;
• a controller board connected to the display interface, the controller board being configured to perform data processing and pixel analysis that determines average pixel values and deviation standards of pixel values in each different segmentation of images;
• a camera integrated with the controller board;
• a camera board to support the camera;
• a sample holder configured to hold a sample;
• a light emitting diode inserted in a wall of the sample holder and located so that the sample held within the sample holder is in front of the light emitting diode, the camera capturing an image of the sample that is excited using light emitted from the light emitted diode, the controller board being configured to perform the data processing and the pixel analysis on the captured image using machine learning algorithms, and the display interface displaying results of the data processing and the pixel analysis on the average pixel values and the deviation standards of pixel values in each different segmentation of the captured image, which indicate a level of Ochratoxin A (OTA) in the sample;
• a reagent holder configured to hold extraction reagents and a nano probe;
• and
• a power bank configured to supply power to the display interface, the controller board, the camera, the camera board, and the light emitting diode.
