Summary: A new detection modality based on immunomagnetic bead aggregation was developed for rapid and label-free detection of enrofloxacin. By exploring the mechanism of bead aggregation and investigating key parameters, a label-free biosensing platform was established for rapid and sensitive detection of enrofloxacin. Two methods were proposed for quantitatively determining enrofloxacin based on differences in magnetic separation speed and size. A 3D-printed syringe was used for automatic filtration of immunomagnetic beads. This immunosensor showed a satisfactory limit of detection and recovery rates, making it applicable to complex food samples.

Summary: This study investigated the sodium hypochlorite tolerance of Salmonella isolated from the poultry supply chain in China and evaluated cross-resistance. The findings showed that a high percentage of Salmonella isolates displayed resistance to multiple antibiotics and exhibited tolerance to chlorine. The presence of chlorine tolerance genes was positively correlated with the minimum inhibitory concentration levels.

Summary: A portable detection device was developed for rapid, sensitive and simple detection of viable Salmonella using a finger-actuated microfluidic chip and an improved recombinase aided amplification (RAA) assay. The device could distinguish viable bacteria from dead ones by combining improved propidium monoazide (PMAxx) with RAA. It could detect Salmonella typhimurium in spiked chicken meats from 1.3 x 10 2 CFU/mL to 1.3 x 10 7 CFU/mL in 2 hours with a lower detection limit of 130 CFU/mL, and showed potential for on-site detection of foodborne pathogens.

Summary: Magnetic relaxation switching (MRS) biosensors are attractive in the field of food safety due to their simplicity and high signal-to-noise ratio. However, they suffer from low sensitivity and stability caused by insufficient crosslinking or non-specific binding of magnetic nanoparticles (MNPs). In this study, the CRISPR-Cas12a system was introduced into an MRS biosensor for the first time to enhance sensitivity and stability for the detection of Salmonella.

Summary: An integrated nanochannel electrode (INCE) with nanoporous gold layers was fabricated and used for small-molecule analysis. Metal-organic frameworks (MOFs) were decorated inside and outside of the nanochannels to capture small molecules and generate current signals. This study provides a new approach for nanopore analysis of small molecules by utilizing the outer surface and internal nanoconfined space of nanochannels.

Summary: In this study, a novel and highly sensitive bacteria detection method was developed based on the dual-confinement effects of size and volume in a nanochannel-electrodes chip. The size confinement in the nanochannels promoted enzyme catalysis efficiency, while the volume confinement in the micro-droplet-based electrochemical cell enriched ions by restricting diffusion. This work contributes to the understanding of nanoconfined processes and provides a new signal transduction technique for trace analysis.
