#1 [14.3] Ultrasensitive Detection of Porcine Epidemic Diarrhea Virus Infections Using Multivalent DNA Nanostructure-Enabled Lateral Flow Assay.

Early, rapid on-site detection of viral pathogens in livestock is critical to prevent disease spread, minimize economic losses, and safeguard food security. However, most current diagnostics are limited to centralized laboratories or require specialized equipment such as electrochemical readers, with a few hours to multi-day turnaround times tha...

#2 [13.0] Ultrasensitive dual-detection of antibiotics in animal-derived foods by nucleic acid signal amplification-assisted magnetic dispersive solid-phase extraction.

BACKGROUND: The presence of diverse residual trace antibiotics in various food matrices may accumulate in the human body through the food chain and potentially pose a significant risk to human health through synergistic effects. Consequently, the development of a sensitive method for the simultaneous detection of multiple antibiotics holds signi...

#3 [12.3] Luminescent hydrogel-enabled electrochemiluminescent aptasensor and portable analyzer for on-site quantification of acetamiprid in vegetables.

Acetamiprid residues in vegetables threaten human health and food safety, necessitating rapid, sensitive detection. Electrochemiluminescence (ECL) is highly sensitive but suffers from matrix-induced quenching and high-voltage photomultiplier tubes (PMT). Here we co-load N-(4-aminobutyl)-N-ethylisoluminol (ABEI), MnO2 nanosheets (MnO2NSs), and go...

#4 [11.5] A supersandwich fluorescent aptasensor leveraging the synergy of mini-nanotetrahedron, high-affinity split aptamer and rolling circle amplification for kanamycin analysis in milk.

Sensitive detection of kanamycin (KAN) is vital for ensuring food safety. In this study, a novel fluorescent aptasensor for KAN detection was developed by synergizing high-affinity split aptamers, a miniaturized DNA nanotetrahedron (mini-NTH) scaffold, and rolling circle amplification (RCA). Contrasting conventional views, the split aptamers exh...

#5 [11.3] Construction of Codirectional Charge Transfer Channels in Imine-Linked Covalent Organic Frameworks with Enhanced Electrochemiluminescence for Ultrasensitive Lincomycin Assay.

Covalent organic frameworks (COFs) have garnered increasing attention in electrochemiluminescence (ECL), but how to improve ECL efficiency is still challenging due to the insufficient charge separation driving forces and non-directional charge transfer. Herein, by rationally modulating the types of building blocks, we synthesize two donor-accept...

#6 [11.0] Double-layer core-satellite magnetic SERS aptasensor for ultrasensitive and interference-free tryptamine detection.

Excessive tryptamine in food poses a significant risk to human health, emphasizing the demand for efficient, sensitive, and rapid detection technologies. Surface-enhanced Raman Spectroscopy (SERS) aptasensors are presently attracting a lot of attention due to their ability to detect targets at low concentrations. However, their inherent instabil...

#7 [10.7] Ratiometric copper nanocluster fluorescence probe coupled with deep learning for intelligent recognition of tetracycline antibiotics in food

In this study, a ratiometric fluorescence sensing strategy combined with deep learning was developed for the intelligent detection of tetracycline antibiotics (TCs) in food matrices. Blue-emitting and saffron yellow-emitting copper nanoclusters (Cu NCs) were synthesized using bovine serum albumin (BSA) and 2,3,5,6-tetrafluorothiophenol (TFTP) as...

#8 [10.5] Enterohemorrhagic Escherichia coli Detection by Aptamer-Functionalized Stokes-Shifted Quantum Dots.

Escherichia coli O157:H7 is a prolific serotype of the Shiga toxin-producing E. coli strain, known for its enterohemorrhagic pathogenicity and transmission in contaminated food and water. The O157:H7 serotype, evolving from the nonpathogenic sorbitol-fermenting O55:H7 strain, is widely implicated as the causative organism in numerous food poison...

#9 [9.7] Easy methodology for linker-free SERS detection of vitamin D(3) at trace levels.

Vitamin D3 is a crucial biomarker for several human diseases. Its deficiency is overcome through pharmaceutical and food supplement interventions. Therefore, its detection at biologically relevant low concentrations or trace levels is crucial. SERS is a powerful analytical technique that combines the molecular specificity of Raman spectroscopy w...

#10 [9.7] Circulating C1QC in cancer: analytical platforms, evidence gaps, and prospects for clinical chemistry translation.

Traditional serum tumor markers, such as carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA 19-9), cancer antigen 125 (CA 125), α-fetoprotein (AFP), and prostate-specific antigen (PSA), exhibit limited diagnostic sensitivity and specificity during the early stages of disease and in malignancies with overlapping clinical features. This...
