#1 [14.5] Coordination‐Driven Metal‐Phenolic Network Complexes for Programmable Colorimetric Signal Transduction and Defined Nano‐Bio Interfaces

Self-assembled coordination networks provide opportunities to engineer functional nanostructures with programmable physicochemical properties, yet their optical responses and nano-bio interfacial interactions remain poorly understood. Herein, we employ a coordination-driven self-assembly approach to construct metal-phenolic network complexes (MP...

#2 [12.2] An aptamer-integrated bimetallic MOF nanozyme for dual-mode colorimetric and fluorescence sensing of bisphenol A.

As a representative endocrine-disrupting compound, bisphenol A (BPA) can leach from food packaging materials into food, thereby presenting potential risks to human health. Therefore, the development of rapid, sensitive, and reliable methods for BPA detection is of great importance. In this study, a dual-mode colorimetric/fluorescence aptasensor ...

#3 [12.1] PdIr bimetallic nanozyme engineered metal-organic frameworks integrated dual-mode sensor toward Stx2 detection in food.

Shiga toxin II (Stx2) has attracted extensive attention due to its toxicity and pathogenicity, making the development of sensitive detection methods urgent. This study constructed a dual-mode sensing platform for the sensitive detection of Stx2 in food. Composite material UIO-66@PdIr with peroxidase-like activity and fluorescent properties was s...

#4 [12.0] Plasmonic response of aptamer-functionalized gold nanoparticles via target-induced aggregation for oxytetracycline detection.

The widespread use of oxytetracycline (OTC) in sericulture to control bacterial infections and improve silkworm productivity has raised significant concerns regarding the emergence of antimicrobial resistance and antibiotic residue accumulation in seri-products, highlighting the need for reliable monitoring strategies. In this work, we report a ...

#5 [12.0] Defect-Engineered Fe-B MOFs with Intrinsic Neutral-pH Recognition for Accelerated Dual-Mode Detection of Staphylococcus aureus.

This study addresses the challenge of achieving sensitive and reliable Staphylococcus aureus detection in neutral-pH food matrices, where conventional boronate affinity ligands typically lose their binding efficiency. We developed a dual-mode colorimetric-electrochemical aptasensor by rationally designing a defect-engineered iron-boronic acid me...

#6 [11.6] Bimetallic valence relay catalysis in EuTb/N-doped carbon nanosheets: temporal decoupling of oxygen reduction resolves competitive kinetics for ultrasensitive electrochemiluminescence detection of L-cysteine

Accurate monitoring of thiol-containing biomolecules is crucial for understanding redox balance in biological systems. However, conventional luminol-based electrochemiluminescence (ECL) systems rely on unstable H2O2 or suffer from low dissolved O₂ solubility and sluggish kinetics, leading to insufficient reactive oxygen species (ROS) generation ...

#7 [11.2] Porous Hydrogel-Mediated One-Step Selection of Mannoprotein-Targeted Aptamers for Early Diagnosis of Invasive Saccharomyces cerevisiae Infections.

Invasive fungal infections, particularly those caused by Saccharomyces cerevisiae, have emerged as a significant public health threat. Accurate and timely recognition of S. cerevisiae is essential for effective diagnosis and treatment. This study introduces a micro- and nanoscale-enabled diagnostic strategy that integrates porous hydrogel-mediat...

#8 [10.9] Novel Electrochemical Aptasensor Based on Iron–Cobalt-Doped Magnetic Carbon and cDNA-Polyacrylic Acid for the Determination of Aflatoxin B1 in Peanuts

The presence of aflatoxin B1 (AFB1) is ubiquitous in the environment, and it is considered one of the most powerful natural carcinogenic substances. In this study, a highly sensitive electrochemical aptasensor was designed to detect aflatoxin B1 (AFB1) in peanuts. Iron–cobalt-doped magnetic carbon (Fe-Co/NPC) was used to enhance the conductivity...

#9 [10.6] Sulfur vacancy-mediated self-photocatalysis-boosted electrochemiluminescence sensing via molecular oxygen activation for sensitive detection of isocarbophos.

The luminol-dissolved oxygen electrochemiluminescence (ECL) system is fundamentally limited by the poor redox activity of oxygen, which fails to generate sufficient reactive oxygen species (ROS) for efficient luminol excitation, restricting the performances of sensors. Herein, a high-performance ECL sensor was fabricated for sensitive detection ...

#10 [10.4] A fluorescent aptasensor based on the synergy of Au NPs/PDDA/LEG nanocomposite and CDs for aflatoxin B1 detection.

Aflatoxin B1 (AFB1), a potent carcinogen produced by Aspergillus fungi, contaminates foods such as corn and peanuts and thereby introduces a serious food safety risk, as it is known to cause liver damage and cancer. Therefore, developing sensitive and rapid detection methods is crucial for protecting public health. This work presented a highly s...
