2D Film‐Like Magnetic SERS Tag with Enhanced Capture and Detection Abilities for Immunochromatographic Diagnosis of Multiple Bacteria

Small, Год журнала: 2024, Номер 20(22)

Опубликована: Янв. 9, 2024

Abstract Here, a multiplex surface‐enhanced Raman scattering (SERS)–immunochromatography (ICA) platform is presented using graphene oxide (GO)‐based film‐like magnetic tag (GFe–DAu–D/M) that effectively captures and detects multiple bacteria in complex specimens. The 2D GFe–DAu–D/M with universal bacterial capture ability fabricated through the layer‐by‐layer assembly of one layer small Fe 3 O 4 nanoparticles (NPs) two layers 30 nm AuNPs 0.5 built‐in nanogap on monolayer GO nanosheets followed by co‐modification 4‐mercaptophenylboronic acid (MPBA) 5,5′‐dithiobis‐(2‐nitrobenzoic acid).The enabled rapid enrichment MPBA quantitative analysis target test lines specific antibodies, thus achieving signal amplification effect multilayer dense hotspots eliminating matrix interference real‐world applications. developed technology can directly simultaneously diagnose three major pathogens ( Staphylococcus aureus , Pseudomonas aeruginosa Salmonella typhimurium ) detection limits down to level 10 cells mL −1 . good performance proposed method real urinary tract infection specimens also demonstrated, suggesting great potential GFe–DAu–D/M–ICA for highly sensitive monitoring infections or contamination.

Enhancing Peroxidase‐Like Activity and Photothermal Property of Copper Single‐Atom Nanozyme via A Cascade Competition Strategy

Advanced Functional Materials, Год журнала: 2025, Номер unknown

Опубликована: Янв. 16, 2025

Abstract Single‐atom nanozymes (SANs) are promising enzyme‐active catalysts due to their maximum atomic utilization. However, it is still a challenge precisely regulate the single‐atom structure, especially in multimetallic MOFs. Based on Cu‐N 4 structure of Zn Cu 1 , cascade competition strategy mediated by buffer (polydopamine) proposed for first time, which induces one‐step nonthermal reaction remove inactive site and adjust coordination environment. Experimental results theoretical calculations show that nanozyme with 2 O (Cu‐N/O) breaks strong steric restriction, exposed active can better adsorb H making have peroxidase‐like activity. Compared traditional bimetallic (Cu ) monometallic (Cu‐MoF) nanozymes, has stronger catalytic activity photothermal properties, as well good photocatalytic extremely stability. It successfully applied Lateral flow immunoassay achieve three‐mode ultrasensitive detection Escherichia coli O157:H7, test strips after subjected broad‐spectrum sterilization treatment.
