#1 [15.0] 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 [14.1] 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 [14.0] 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 [12.2] 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...

#5 [11.8] 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...

#6 [11.4] 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...

#7 [11.0] 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...

#8 [10.0] A truncated aptamer-based electrochemical sensor for sensitive Ara h 1 determination on gold nanoparticle-modified screen-printed electrodes.

Food allergy, a worldwide health problem due to its rising prevalence, is an immune reaction to allergens. Among these, peanut allergy poses significant health risks and underscores the critical need for accurate detection methods. This study focuses on developing an electrochemical aptasensor based on a gold nanoparticle and Ara h 1 specific ap...

#9 [9.8] The GA-optimized MSPE measurement for high-performance electrochemical detection of bacterial pathogens in complex matrices.

To address the limited generalizability and matrix interference in foodborne bacterial detection within complex food matrices, a high-performance electrochemical detection platform enabled by genetic algorithm (GA)-optimized magnetic solid-phase extraction (MSPE) was developed. Magnetic electrochemiluminescent probes were functionalized with bac...

#10 [9.3] Aminated PET Thin Film as a Functionalized Insulating Layer for Capacitive Gliadin Aptasensor Construction

Celiac patients require strict avoidance of gliadin, the primary immunotoxic component of gluten, making sensitive detection essential for food safety. A label-free and reagentless capacitive aptasensor for gliadin detection was developed using an aminated polyethylene terephthalate (PET) thin film as both an insulating layer and functionalizati...
