Rapid detection of trichlorfon residues by a microfluidic paper- based phosphorus- detection chip ( lPPC)

摘要

We propose a novel microfluidic paper-based phosphorus-detection chip (PPC) for rapid analysis of trichlorfon, one of the most common organophosphate pesticide residues. The semi-quantification method was established and the limit of detection was 1.65 g mL(-1). We believe that the PPCs could be a promising approach for the rapid determination of organophosphate pesticides.
