#1 [13.3] 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...

#2 [12.6] 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...

#3 [11.8] 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...

#4 [11.7] 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...

#5 [11.3] 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...

#6 [11.0] 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...

#7 [10.8] 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...

#8 [10.0] 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...

#9 [9.8] Ag-Ti(3)C(2)T(x) MXene mediated H(2)O(2) reduction for electrochemical biosensing of kanamycin in real samples based on split aptamer engineering strategy.

To resolve the conflict between multidimensional interferences derived from complex matrices and the stringent requirements for trace-level detection sensitivity, a novel electrochemical aptasensor was constructed for highly sensitive kanamycin (KANA) detection based on a split aptamer engineering strategy. Ag-Ti3C2Tx MXene, synthesized via in-s...

#10 [9.1] Transcription Factors: A Promising Third-Generation Core Sensing Element for Developing Low-Cost, On-Site Rapid Detection Technologies for Food Contaminants.

Biosensors couple biological recognition elements with signal transducers to provide rapid, low-cost alternatives to conventional food analysis. Beyond antibodies and aptamers, transcription factors (TFs) are emerging as highly sensitive recognition modules because they deliver intrinsic transcriptional signal amplification. TF-based sensors are...
