In Situ Single Au@Cu₂O Core–Shell Nanoparticle Analysis-Enhanced Ultrasensitive Detection of Biothiols Using Light Scattering Imaging

Analytical Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: May 1, 2025

Dark-field microscopy (DFM) as a single particle analysis (SPA) technique has been developed rapidly in recent years because of its high signal-to-noise ratio, enhanced sensitivity, and sufficient spatial temporal resolution. Here, an situ Au@Cu2O core-shell nanoparticle (Au@Cu2O NP) light scattering imaging was reported to realize the ultrasensitive detection biothiols-cysteine (Cys) glutathione (GSH). Based on specific binding Cu(I) with -SH formation Cu-S bond, it triggered decomposition Cu2O shell exposure Au nanorods (Au NRs) presence biothiols. Moreover, process dissolution observed real time under DFM, which indicated that color changed from bright green dark red intensity decreased, correspondingly. Compared ex SPA, SPA exhibited significantly sensitivity due effect concentration polarization, linear correlations over broad ranges (Cys: 0.05-3 nM, GSH: 0.1-10 nM), low limits 15.52 pM 75.07 Therefore, this work provides smart strategy find promising applications for biomolecules through SPA.

Facilitating Charge Separation of Donor–Acceptor Conjugated Microporous Polymers via Position Isomerism Strategy for Efficient CO2 Photoconversion

Catalysts, Journal Year: 2024, Volume and Issue: 14(10), P. 659 - 659

Published: Sept. 24, 2024

Photoreduction of CO2 into the chemical feedstocks fuels provides a green way to help solve both energy crisis and carbon emission issues. Nevertheless, undesirable charge separation migration, as well rapid reverse recombination results in unsatisfactory photocatalytic activity most conjugated microporous polymers (CMPs). Herein, pair donor–acceptor (D-A) CMPs for photoconversion was developed through position isomerism by altering linkage sites. The show that Py-D27F with 2,7-site exhibits completely structure large molecular dipole moment, thus significantly accelerating transfer. As result, achieves higher yield 320.9 μmol g−1 h−1 CO2-to-CO photoreduction (without addition any photosensitizers precious metals), which is about three-fold greater than Py-D36F (3,6-site linkage). This study valuable idea exploring outstanding CMP photocatalysts efficient processing photocatalysis.
