“…For the detection of metal ions, the traditional detection methods mainly include inductively coupled plasma atomic emission spectrometry (ICP-AES) [21], atomic absorption spectrometry (AAS) [22], electrochemical method [23], spectrophotometry [24]. While the traditional detection techniques for H 2 S contains electrochemical analysis [25], colorimetric method [26], spectrophotometry and gas chromatography [27,28].…”

In order to better monitor the content of Fe3+ and H2S in the biological environment, two new fluorescent probes were designed and synthesized. With the addition of Fe3+, the strong fluorescence emission of two probes was significantly quenched due to the paramagnetic effect of Fe3+. After the addition of S2−, the fluorescence intensity of two probes was quickly restored. Two probes showed high selectivity and strong sensitivity for the detection of Fe3+ and S2−, and the fluorescence intensity “ON-OFF-ON” was accompanied with the interaction process. At the same time, two probes displayed good anti-interference ability which was not interfered by the existence of other ions. In addition, two probes illustrated fast response time to Fe3+, S2− and small cytotoxicity to cells. Therefore, two probes can provide a potential ideal tool for detecting Fe3+ and H2S in organisms and the environment.
