Abstract

A novel magnetic fluorescent nanoprobe (Fe₃O₄@ZnS@MPS(MFNPs)) was synthesized, which recognized and cooperated with Ag⁺ ions, and a rapid method for detecting Ag⁺ was established in solution. It was found by fluorescence spectroscopy analysis that the MFNPs could detect Ag⁺ in PBS solution and, upon addition of Ag⁺ ions, the fluorescence (FL) of MFNPs could be quenched significantly. The sensor has a low limit of detection (LOD) of 7.04 µM for Ag⁺. The results showed that MFNPs were extremely specific and sensitive for the quantitative detection of Ag⁺ over a wide pH range. Then, the recognition mechanism between MFNPs and guest Ag⁺ was explored via measures of infrared spectroscopy and electron microscopy. It was speculated that the oxygen atoms in the sulfonic acid group cooperated with Ag⁺ to form a synergistic complexation. The assay was successfully used to determine the content of Ag+ in real samples.
