N2 - Anion detection gain wide interest because anions play important roles in many fields. Microfluidic paper analytical devices (μPADs) are promising for monitoring anions due to their low cost, short time analysis, and simple operation. In this work, we demonstrated the utilization of 8-hydroxyquinoline zinc (Znq2) nanocrystal (NCs), immobilized on μPADs for anion detection. By controlling the pH using MES buffer pH 5, Znq2 NCs showed prominent detection of anions. By applying a proper concentration of Zn2+ solution, Znq2 NCs show an obvious color change even at a low millimolar level which is possible to detect the anions in a real sample application.
