Dual-Signaling Photoelectrochemical Biosensor Based on Biocatalysis-Induced Vulcanization of Bi₂MoO₆ Nanosheets

Analytical Chemistry, Год журнала: 2022, Номер 94(32), С. 11441 - 11448

Опубликована: Авг. 3, 2022

A magnetic-assisted photoelectrochemical (PEC) and colorimetric (CL) dual-modal biosensing platform with high precision was established to monitor prostate-specific antigen (PSA) based on Bi2MoO6 nanosheets (BMO) by coupling the aptamer-guided hybridization chain reaction (HCR) hydrolysate-induced vulcanization of nanosheets. Upon addition PSA, trigger DNA (tDNA) released interaction between target analyte aptamer then further hybridized anchor (aDNA) conjugated magnetic beads (MBs). The as-released tDNA initiated target-assisted HCR in presence two alternating hairpin sequences (Bio-H1 Bio-H2) produce nicked long double-stranded surface MBs, where numerous alkaline phosphatase (ALP) enzymes could assemble MBs through biotin–avidin reaction, resulting hydrolysis sodium thiophosphate (TP) H2S. as-produced H2S reacted BMO form vulcanized (BMO-S), thus leading obvious enhanced PEC performance under visible light color change from yellow brown. Having optimized test conditions, system holds a good quantitative diagnosis sensitivity area range 5.0 pg mL–1–100 ng mL–1 calculated detection limit down 3.5 mL–1. Meanwhile, visual assay basis materials also realized. Given exceptional constructed biosensor, it may possess great promise as an advanced bioanalytical tool for practical applications.

Single‐Atom Rh on High‐Index CeO₂ Facet for Highly Enhanced Catalytic CO Oxidation

Angewandte Chemie International Edition, Год журнала: 2023, Номер 62(28)

Опубликована: Май 11, 2023

Reducible oxide-supported noble metal nanoparticles exhibit high activity in catalyzing many important oxidation reactions. However, atom migration under harsh reaction conditions leads to deactivation of the catalyst. Meanwhile, single-atom catalysts demonstrate enhanced stability, but often suffer from poor catalytic owing ionized surface states. In this work, we simultaneously address and stability issues by synthesizing highly active durable rhodium (Rh) through a "wrap-bake-peel" process. The pre-coated SiO2 layer during synthesis catalyst plays crucial role not only protecting CeO2 support against sintering, also donating electron weaken Ce-O bond, producing loaded Rh single atoms on exposed with high-index {210} facets. Benefiting unique electronic structure facets, more oxygen vacancies are generated along deposition electropositive atoms, leading remarkably improved performance CO oxidation.
