#1 [13.3] 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...

#2 [12.5] 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...

#3 [12.3] 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...

#4 [12.0] 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...

#5 [10.7] 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...

#6 [10.5] 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...

#7 [10.1] CRISPR-Cas12a-regulated photo-ATRP for ultrasensitive detection of lipopolysaccharide.

Lipopolysaccharide (LPS), a primary virulence factor produced by Gram-negative bacteria, demands rapid and ultrasensitive detection for safeguarding food safety and supporting clinical diagnosis. This study developed a novel electrochemical biosensing platform by integrating the programmable recognition of CRISPR-Cas12a with the high-gain signal...

#8 [9.7] 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...

#9 [9.4] A novel CRISPR/Cas14a-synergized wood-based platform for the ultrasensitive detection of aflatoxin B1.

A CRISPR/Cas14a-synergized wood-based platform (CWP) is designed here to detect aflatoxin B1 (AFB1) at an LOD of 0.67 fmol L-1 with high sensitivity and no preamplification. Once the assay is performed, AFB1 is optically identified through an aptamer competition process, which triggers the trans-cleavage activity of Cas14a, resulting in signific...

#10 [9.3] A label-free fluorescent aptasensor based on DNA-templated silver nanoclusters and catalytic hairpin assembly for highly specific detection of Escherichia coli O111:B4 lipopolysaccharide.

BACKGROUND: Escherichia coli O111:B4 is an important diarrheagenic serotype and an indicator of fecal contamination in water quality monitoring. Its specific detection remains challenging because of the high structural similarity among E. coli serotypes and limitations in conventional assays. Serotype-specific lipopolysaccharide (LPS) is a stabl...
