Multidimensional Interactive Cascading Nanochips for Detection of Multiple Liver Diseases via Precise Metabolite Profiling

Advanced Materials, Journal Year: 2024, Volume and Issue: 36(21)

Published: Jan. 24, 2024

Abstract It is challenging to detect and differentiate multiple diseases with high complexity/similarity from the same organ. Metabolic analysis based on nanomatrix‐assisted laser desorption/ionization mass spectrometry (NMALDI‐MS) a promising platform for disease diagnosis, while enhanced property of its core nanomatrix materials has plenty room improvement. Herein, multidimensional interactive cascade nanochip composed iron oxide nanoparticles (FeNPs)/MXene/gold (AuNPs), IMG, reported serum metabolic profiling achieve high‐throughput detection liver diseases. MXene serves as multi‐binding site an electron‐hole source ionization during NMALDI‐MS analysis. Introduction AuNPs surface plasmon resonance (SPR) properties facilitates charge accumulation rapid energy conversion. FeNPs are integrated into MXene/Au nanocomposite sharply reduce thermal conductivity negligible heat loss strong thermally‐driven desorption, construct multi‐interaction proton transport pathway ionization. Analysis these fingerprint signals detected IMG through neural network model results in differentiation via single pass revelation potential biomarkers. The method can rapidly accurately screen various diseases, thus allowing timely treatment

Cd Single Atom as an Electron Mediator in an S‐Scheme Heterojunction for Artificial Photosynthesis of H₂O₂

Advanced Energy Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 13, 2025

Abstract Developing conductor‐mediated S‐scheme heterojunction photocatalysts imitating natural photosynthetic systems emerges as a promising approach to hydrogen peroxide (H 2 O ) production. However, achieving precise coupling between two semiconductors with charge shuttle and modulating the interfacial interactions still remain significant bottleneck. Herein, we propose catalyst architecture Cd single atom mediated formed by interfacing CdS TiO nanoparticles. This exhibits an H production rate high 60.33 µmol g −1 min under UV–vis light irradiation, which is attributed efficient transport at interface of thanks S‐scheme. In‐situ X‐ray photoelectron spectroscopy (XPS) electron spin resonance (ESR) spin‐trapping tests confirm transfer route. Femtosecond transient absorption (fs‐TA) other ex‐situ characterizations further corroborate across interface. work offers new perspective on constructing atoms heterojunctions enhance photocatalytic performance.
