A μPAD may include a paper-based substrate and a non-polar material printed on a surface of the substrate such that a portion the surface is exposed. The exposed portion may include a receiving area, a plurality of test areas, and a plurality of channels disposed between the receiving area and the test areas. The μPAD may further include colorimetric sensors respectively positioned in the test areas. The channel regions may be configured to receive an analyte solution from the receiving area and direct the analyte solution to the colorimetric sensors. A system may perform image processing on captured images of the μPAD to provide multiplexed analysis of analyte solutions applied to the μPAD.
