#1 [16.4] Advancing point-of-care diagnostics: Engineering and enhancing sensitivity and specificity in nanoparticle-based lateral flow assays for rapid disease detection.

Lateral flow assay (LFA) is the most widely used point-of-care (PoC) diagnostic tools due to their simplicity, rapid turnaround, portability, and low cost. Despite their extensive adoption in clinical diagnostics, food safety, and environmental monitoring, conventional LFA remain limited by inadequate sensitivity, poor quantification, and restri...

#2 [16.4] Switch-type photoelectrochemical aptasensor for microplastics and nanoplastics detection based on two-dimensional organic-inorganic heterojunction.

Microplastics and nanoplastics (MNPs) as emerging pollutants present substantial risks to both the environment and human health. Developing highly sensitive methods to rapidly identify and detect low concentrations of MNPs in complex systems remains a considerable challenge. Here, an "off-on" switch-type photoelectrochemical (PEC) aptasensor was...

#3 [13.4] 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...

#4 [13.0] 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...

#5 [12.3] An immune-inspired intelligent aptasensor with broad detection capability.

Biosensors, particularly aptasensors, play a pivotal role in rapid diagnostics, but their practical performance is limited by suboptimal aptamers and conventional aptamer-material combination-based approaches. To overcome the limitations, we drew inspiration from living systems by pioneering an immune-inspired biomimetic strategy that harnesses ...

#6 [12.2] On-site AFB1 detection in food via dual-gated system and Zn2+-doped UCNPs embedded in injectable PGB hydrogel

#7 [12.2] New insights of aptamer as tools for food allergen management: From novel detection strategies to active control

#8 [12.0] 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 [11.8] Fabrication of a Robust and Ultra-Sensitive SERS Platform via photoaffinity labeling-mediated Oriented and Covalent Antibody Immobilization for Aflatoxin B1 Biosensing

#10 [11.8] 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...
