Analytical Chemistry, Год журнала: 2025, Номер unknown

Опубликована: Янв. 15, 2025

Arginine (Arg) is involved in tissue metabolism and regulates the immune function; thereby, achieving detection of Arg crucial for early diagnosis treatment diseases. Herein, dual ratiometric fluorescence sensors were prepared with blue emission levorotatory/dextrorotatory carbon dots (CDs) red porphyrin (L/D-CDs-PP) sensitive portable Arg. Interestingly, L-CDs-PP D-CDs-PP displayed not only peaks at 493 650 nm but also different response modes to Arg; thus, they could serve as achieve accurate reliable Arg, limit 23.87 μM 2.39 D-CDs-PP. Importantly, solid-state successfully achieved dual-mode visual support a smartphone platform. In addition, exhibited excellent biocompatibility cell imaging capabilities, cells biological samples urine rat plasma. Therefore, broad application prospects fields analytical sensing, imaging, medical diagnosis.

A stereodynamic probe of Pt(II) molecular hinge for chiroptical sensing of cryptochiral compounds

Nature Communications, Год журнала: 2025, Номер 16(1)

Опубликована: Фев. 25, 2025

Cryptochiral compounds are indispensable in biology systems and medical applications, yet the development of high-performance detection method remains challenging. Here, we report a hinge-like dinuclear Pt(II) complex as stereodynamic probe for cryptochirality sensing. This features constrained, closed conformation achieved through synergistic intramolecular π − stacking metal-metal interactions between cyclometalated wings. The shows robust chiroptical response to center-to-axial chiral induction during rapid condensation with cryptochiral that adopts more energetically favorable conformation. resulting intense Cotton effects at long wavelengths enable in-situ circular dichroism analysis determinate absolute configuration enantiometric composition molecules. Furthermore, near-infrared phosphorescence characteristics hinge have been explored develop it an optical sensor accurate quantification With its dual CD capabilities, this great potential high-throughput screening analysis. authors complexes probes
