Rapid detection of trichlorfon residues by a microfluidic paper-based phosphorus-detection chip (μPPC)†
Abstract
We propose a novel microfluidic paper-based phosphorus-detection chip (μPPC) 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 μg mL−1. We believe that the μPPCs could be a promising approach for the rapid determination of organophosphate pesticides.
