Smartphone controlled platform for point-of-care diagnosis of infectious diseases

In this work, we present the development of a point-of-care platform for the serologic diagnosis of infectious diseases. The complete system consists of magnetic particles with immobilized antigens, disposable electrochemical cells, hardware and software. The main purpose of this paper is to present the last two components. The platform is powered by a rechargeable battery and can be controlled using mobile devices, allowing point-of-care diagnosis of diseases. The platform was successfully tested for the diagnosis of foot-and-mouth disease, human and bovine brucellosis, and Chagas disease.
