Abstract

We are the first to integrate H2O2 degradation and gold nanorod (GNR) etching on paper with the lateral-flow immunoassay (LFA) in a 3D-printed device to achieve semi-quantitative results for therapeutic drug monitoring of digoxin by correlating different color outputs to different digoxin concentrations.
