“…Up to now, many methods have been developed to detect SO 2 , including electro-chemistry, [12,13] ion chromatography, [14][15][16] capillary electrophoresis, [14,17,18] HPLC, [19,20] polarography, [21] FIA, and so on. [22] The main disadvantage of these methods was that most of them required various pretreatment to samples.…”

Sulfur dioxide is one of the reactive sulfur species, which has significant physiological functions in cells. Some physiological processes are closely related to SO 2 in organisms, and the high concentration of SO 2 in living cells can cause many diseases. In order to investigate the unique function of SO 2 at the subcellular level, developing a molecular tool which could detect of SO 2 within organelles is imperative. Hence, we developed a cationic dye named HQ-SO 2 as a new fluorescent probe to specifically monitor SO 2 , which was easy to obtain through one-step reaction. It took Michael addition reaction as the mechanism of reaction for detection of SO 2 . In addition, this probe showed a series of highly favorable properties such as rapid response rate, low cytotoxicity, high selectivity, low detection limit, and good photostability, which enabled the probe to track SO 2 in living cells.

Preparing compounds containing the radioisotope 64 Cu for use in positron emission tomography cancer diagnostics is an ongoing area of research. In this study, a highly efficient separation method to recover 64 Cu generated by irradiating the target 64 Ni with a proton beam was developed by employing a flow electrolysis cell (FE). This system consists of (1) applying a reduction potential for the selective adsorption of 64 Cu from the target solution when dissolved in HCl and (2) recovering the 64 Cu deposited onto the carbon working electrode by desorbing it from the FE during elution with 10 mmol/L HNO 3 , which applies an oxidation potential. The 64 Cu was selectively eluted at approximately 30 min under a flow rate of 0.5 mL/min from the injection to recovery. The newly developed flow electrolysis system can separate the femtomolar level of ultratrace radioisotopes from the larger amount of target metals as an alternative to conventional column chromatography.
