Multiplex smartphone diagnostics

Abstract

Increasing computing power in smartphones allows for their transformation into point-of-care diagnostic devices. Mobile medical diagnostic applications enable utilization of the processing capabilities of smartphones through their cameras. Hardware attachments or stand-alone versions of smartphone diagnostics have the capability to revolutionize quantitative readouts. Here, we describe a protocol for quantifying commercial colorimetric diagnostic tests with a stand-alone smartphone application. This approach can be used in the multiplexed analyses of biomarker readouts.
