Summary: A photoelectrochemical sensor based on an Au-mediated Z-scheme TiO2-Au-BiOI (HTNTs-Au-BOI) platform is proposed for the detection of L-Cysteine (Cyst). The platform, with the mediating effect of Au NPs, enhances light absorption and promotes the formation of Z-heterojunction HTNTs-Au-BOI, which significantly suppresses the recombination of photogenerated electron-hole pairs and improves the sensitivity of the sensor. The dual-specificity of Bi-S and Au-S bonds enables highly selective and sensitive detection of Cyst. The PEC sensor exhibits a wide linear detection range of 80 nM-200 μM with a detection limit of 70 nM. It also shows good results in the detection of serum samples, with a relative standard deviation (RSD) of 0.68-7.3%.

Summary: Two new all-cis pyrene-substituted cyclic tetrasiloxanes (JR-01 and JR-02) have been synthesized and studied as selective metal ion sensors. Both compounds exhibit solvent-and concentration-dependent excimer fluorescence emission at 482 nm. They also show highly selective fluorescence quenching by Au(III) ion with detection limits of 0.9 and 0.8 mu M for JR-01 and JR-02, respectively. Data from various experiments indicate a plausible mechanism involving the formation of a non-emissive Au(III) complex.

Summary: The synthesis of Au cluster-cored dendrimers, both by direct synthesis and multi-step functionalization pathways, has been described in this study. It was found that the directly synthesized cluster-cored dendrimers had larger core sizes and higher catalytic activities compared to those formed by the divergent approach. However, the divergently synthesized dendrimers exhibited better stability and smaller core sizes.

Summary: Liver disease is a major cause of global mortality, and identifying biomarkers for diagnosing its progression is crucial for improving outcomes. Targeted mass spectrometry is a powerful tool for verifying biomarker candidates and clinical applications, particularly for glycoproteins translation. However, the limitation of analyzing only one sample per run has become apparent. In this study, a high-throughput intact N-glycopeptides quantification strategy was developed, allowing the validation of 20 samples per run with an average analysis time of 3 minutes per sample. The strategy was applied in a cohort of 461 serum samples and identified a panel of 10 IgG N-glycopeptides that have strong clinical utility in evaluating the severity of liver disease.
