Antibacterial Mechanism and Flavour Impact of Ultrasound and Plasma-Activated Water Combination on in Crayfish.

is a foodborne pathogen commonly found in contaminated crayfish. In this study, the effects of ultrasound combined with plasma-activated water (US-PAW) against and on the flavour of crayfish were investigated to evaluate their impact on crayfish preservation. In vitro, US and PAW showed a significantly synergistic inhibition against growth and biofilm reformation at 7 min.

Polyphenol-modified 3D Nanoassemblies: A novel antibacterial immunoglobulins loading platform for rapid detection of Salmonella typhimurium.

Within the realm of lateral flow assay (LFIA), the conjugation efficiency between signal tracers and antibody constitutes a pivotal determinant for the sensitivity of the detection system. In this study, three-dimensional (3D) complex flower-like MoS self-assembled from 2D MoS, and natural plant polyphenols "Tannic acid" were introduced for surface modification. This composite material exhibits distinct colorimetric signals, excellent monoclonal antibody coupling efficiency, and commendable photothermal properties.

"Lock-and-key" recognizer-encoded lateral flow assays toward foodborne pathogen detection: An overview of their fundamentals and recent advances.

In light of severe health risks of foodborne pathogenic bacterial diseases, the potential utility of point-of-care (POC) sensors is recognized for pathogens detection. In this regard, lateral flow assay (LFA) is a promising and user-friendly option for such application among various technological approaches. This article presents a comprehensive review of "lock-and-key" recognizer-encoded LFAs with respect to their working principles and detection performance against foodborne pathogenic bacteria.

Nanosheet antibody mimics based label-free and dual-readout lateral flow immunoassay for Salmonella enteritidis rapid detection.

Portable devices for on-site foodborne pathogens detection are urgently desirable. Lateral flow immunoassay (LFIA) provides an efficient strategy for pathogens detection, however, antibody labeling independence and detection reliability, are still challenging. Here, we report the development of a label-free LFIA with dual-readout using glucan-functionalized two-dimensional (2D) transition metal dichalcogenides (TMDs) tungsten disulfide (WS) as detection probes for sensitive detection of Salmonella enteritidis (S.

Joint-detection of Salmonella typhimurium and Escherichia coli O157:H7 by an immersible amplification dip-stick immunoassay.

To explore the superiority of multifunctional nanocomposites and realize the joint-detection of foodborne pathogens, an immersible amplification dip-stick immunoassay (DSIA) was exploited for the sensitive detection of Salmonella typhimurium (S. typhi) and Escherichia coli O157:H7 (E. coli O157:H7).
