Iodide is known as an essential nutrient for the human body. However, long-term deficiency of iodide leads to goiter and thyroid atrophy, while an excess of iodide prevents the ability of thyroxine and triiodothyronine, which control many metabolic activities in the human body. In this present study, a triangular silver nanoplate-based colorimetric sensing system was developed for iodide detection. Since the sharp corners of the triangular Ag nanoplates are very unstable, the triangular Ag nanoplates are easily transformed into a spheroidal shape by chemical etchants, accompanying dramatically changes in the localized surface plasmon resonance (LSPR) properties. Based on this correlation, we developed a novel sensing system for iodide. |
