A Tetrazine-Metal-Polyphenol Nanoprobe for Single-Tube Multimodal Sulfide Analysis.
Reliable sulfide analysis in complex matrices remains challenging because single-signal probes are susceptible to interference and ambiguous readouts. Here, we report a tetrazine-metal-polyphenol nanoprobe, RhB@Tz-MPN, for a single-tube sequential multimodal workflow for sulfide analysis. Sulfide produces three role-di...
