With Find anyone can have access to a timely diagnostic even in the most remote areas of the world.The Find platform uses shark antibodies modified with genetic engineering to detect disease biomarkers in blood, saliva, urine or water samples. These shark antibodies are used in microfluidic cards and generate a visual reactions when in contact with specific biomarkers of the disease to be tested. Then to evaluate the result of the test, a picture of the testing card is taken with the proprietary Xplora smartphone app which runs image analysis process and neural network algorithms to generate an inmediate result. Then this result,along with contextual information like geolocation, date and time, is sent to a cloud server where it can be used for real time disease tracking.
