Summary: This study demonstrates that Ru(bpy)(3)(2+) as a potential liquid electrolyte can have tunable magnetic properties through applied electrode potentials, as evidenced by energy resolved magnetic circular dichroism (MCD). The transition of MCD signal from paramagnetic to nonmagnetic behavior is attributed to the disappearance of metal to ligand charge transfer transition during the electrochemical oxidation process. This work provides valuable insights into exploring functional liquid electrolytes with tunable opto-magnetic properties.

Summary: Intercellular proximity labeling is a promising method for studying cell-cell interactions, but current platforms have limited efficiency. In this study, we developed an efficient photocatalytic proximity labeling system using Ru(bpy)(3)(2+) on the cell surface, allowing highly accurate detection of cell-cell interactions with spatiotemporal resolution. Through mechanism study and quantitative characterization on living cells, we found that the singlet-oxygen mechanism is more efficient and specific than the single electron transfer mechanism in Ru-mediated proximity labeling. We also developed a live T cell receptor multimer with TCR-T cells based on this system, which can sensitively identify and discriminate cells presenting antigens of different affinity, providing a powerful tool for understanding the heterogeneity of antigen presenting cells.

Summary: The study explored the solvent-dependent photoluminescence quenching mechanism of [Ru(bpy)(2)(bpy-cc-AQ)](2+), revealing significant impacts of solvent polarity on its photophysics. In high polarity solvents, competition between factors favoring charge-separated state and photoluminescent (MLCT)-M-3 state results in an unusual temperature dependence of photoluminescence.

Summary: A specificity recognition molecularly imprinted electrochemiluminescence sensor (MIECLS) for determination of clenbuterol (CLB) was established, with a detection limit of 3.3 x 10(-10) mol L-1. The sensor utilized Fe2O3 as the carrier to fix Ru(bpy)(3)(2+), and introduced molecular imprinted membranes (MIPs) with CLB as template molecules to achieve specificity identification, showing great potential in pork and liver samples testing.

Summary: We have successfully synthesized a new functional and atomically precise supramolecular silver nanocluster by coassembling a star cluster and a photosensitizer. The resulting nanocluster exhibits distinct singlet oxygen generation and two-photon excited photoluminescence compared to the pure nanocluster.

Summary: Ru(bpy)(3)Cl-2/TPrA is a prominent ECL system, but limitations in toxicity, volatility, and cost of TPrA restrict its applications. By using arginine as an alternative co-reactant for Ru(bpy)(3)(2+), excellent detection performance is achieved.

Summary: In this study, the cathodic electrochemiluminescence (ECL) of tris(2,20-bipyridine)ruthenium(ii) (Ru(bpy)32+) was achieved at a low potential on porous partially reduced graphene oxide (PPRGO), which minimized electronic damage to biomolecules. By utilizing the quenching effect of MoS2 nanoflowers, a sandwich signal-off ECL immunosensor was constructed for sensitive detection of carcinoembryonic antigen (CEA) with high specificity, stability, and reproducibility. This proposed strategy has potential applications in clinical detection.

Summary: In this study, a designed Ru(bpy)(3)(2+) embedded MOF complex (RuMOFs) is used for high-quality imaging of electrochemiluminescence (ECL) events at a single molecule level. The efficient capture of ECL photons generated inside the MOFs allows for stable ECL emission for up to 1 hour, enabling the visualization of protein movements at the cellular membrane. Compared to fluorescence observation, the near-zero ECL background provides better contrast for dynamic imaging of discrete protein movement.
