Abstract

Microfluidic paper-based analytical devices (µPADs) that display semi-quantitative analysis results by reading a QR code have been developed. The only user operation required is to apply the sample and to read the displayed QR code with a mobile device to obtain the result. Copper ions were detected as a model target and the copper ion concentration-dependent display of QR codes was achieved. This simple assay method can be applied to other targets and has great potential for point-of-care testing (POCT) applications.
