The overview of the present study. A PMMA base plate multi-layered adhesive-coated poly-vinyl film microfluidic device is shown in the middle. The Glucose Oxidase-Peroxidase reaction for colorimetric estimation of glucose is carried out in the device. The output color intensity for glucose samples is captured with the help of a smartphone containing the “GLUCOLENS AI” application. The processed images are classified using a Convolution-Neural Network (CNN) deep learning classifier and the resulting glucose concentration is displayed in the application.
