Abstract

In this study, dopamine passivated carbon nanodots (C-dots) were fabricated to detect ferric ions (Fe³⁺) sensitivity and selectivity. Photoluminescence (PL) intensity of C-dots was turned on after adding phenyl boric acid. Depending on the interesting PL property, we investigated a novel strategy for Fe3+detection. Comparing to the previous papers used complicated and tedious process to fabricate nanomaterial-based probes for Fe³⁺ sensing, the one-pot hydrothermal method spend only 2 h to prepare C-dots from dopamine and trisodium citrate. The limit of detection (LOD) is 5.8 nM, which is lower than these papers.
