Precision-Engineered Co-N -C Single Atoms Enhance Potential-Resolved Ru(bpy) Electrochemiluminescence via Reactive Oxygen Species.

Electrochemiluminescence (ECL) immunoassays based on tris(bipyridine)ruthenium [Ru(bpy) ] is the luminophore representing the most advanced and widely adopted approach in the field of in vitro diagnostics (IVD). However, the scarcity of potential-resolved ECL promoters for Ru(bpy) markedly limits its application in clinical diagnostics. Here, we report the first application of cobalt single-atom catalysts (SACs) designed via density functional theory (DFT) calculations to boost the multi-signal ECL of Ru(bpy) .

Achieving Tunable Mechanoluminescence in CaZnOS:Tb, Sm for Multicolor Stress Sensing.

Mechanoluminescent (ML) materials can exhibit visible-to-near-infrared mechanoluminescence when responding to the fracture or deformation of a solid under mechanical stimulation. Transforming mechanical energy into light demonstrates promising applications in terms of visual mechanical sensing. In this work, we synthesized the phosphor CaZnOS:Tb, Sm, which exhibited intense and tunable multicolor mechanoluminescence without pre-irradiation.
