Iodine is a vital micronutrient required for the production of the thyroid hormone and plays an important role in regulating muscle tissue growth, cell metabolism, and neuronal development. However, insufficient or excessive iodine intake can lead to serious health problems. In this present study, we developed a novel surface passivation method based on a single-step water-based process and showed that it significantly improved the chemical stability of Ag nanoprisms. Specifically, TMEDA-treated Ag nanoprisms retained their triangular shape even when exposed to various strong. Only in the presence of iodide did the sharp corners of the nanoprisms become spontaneously etched, and this etching resulted in a dramatic change in their localized surface plasmon resonance (LSPR) properties. Based on this correlation, we developed a novel sensing system for iodide. |
