#1 [13.1] An integrated litmus test platform for low-background detection and photothermal inactivation of Salmonella typhimurium via HCR-urease signal amplification.

Herein, we propose a novel "low-background" biosensing platform integrating magnetic separation and hybridization chain reaction (HCR) for signal amplification, enabling ratiometric colorimetric detection and visual observation of S. typhimurium. In the presence of S. typhimurium, specific aptamer recognition triggers the HCR to couple the ureas...

#2 [12.5] Spatially confined programmable DNA hydrogel scaffolds accelerate Cas12a trans-cleavage for digital bioimaging.

Molecule diffusion limits target detection in conventional homogeneous solution, typically resulting in inefficient target-probe collision efficiency, low reaction kinetics, and insufficient signal accumulation. Herein, a dual rolling circle amplification-based DNA hydrogel was constructed to establish a hydrogel confined digital imaging platfor...

#3 [11.5] Deciphering fluorine-fluorine interaction in an AIE-active trifluoromethyl-COF for trifluralin detection in the food chain

#4 [10.8] Surface engineered nitrogen doped carbon quantum dots for mechanistic understanding and advanced biosensing of antibiotic contaminants: a review.

Nitrogen-doped carbon quantum dots (N-CQDs) have emerged as a versatile platform for antibiotic biosensing, yet the field has been hindered by empirical optimization without mechanistic understanding. This review establishes quantitative structure-property-performance relationships that enable rational sensor design. We demonstrate that surface ...

#5 [10.7] Electrochemical aptasensor based on DNA nanoflowers for the sensitive detection of acrylamide.

As a prevalent heat-induced byproduct, acrylamide (AA) is frequently generated during thermal food processing, particularly in baked and fried goods. It is a Group 2A carcinogen produced via the Maillard reaction and exhibits neurotoxicity as well as reproductive and developmental toxicity. In this work, DNA nanoflowers (DNF) with remarkable sig...

#6 [10.7] A 3D Multiarm PEG/Aptamer-Engineered Interface with Superior Antifouling and Selectivity for Trace Aflatoxin Profiling

Abstract It is challenging to develop a highly selective and antifouling mass spectrometry (MS) ionization interface for the rapid and sensitive detection of trace analytes in complex matrices, such as aflatoxins (AFs) in Traditional Chinese Medicines (TCMs) and milk. In this study, a bifunctional 8-arm PEG derivative (NH2HCl-8armPEG10K-(MTz)7) ...

#7 [10.6] Dual MOFs synergistically modulate electrode interface electron transfer to enhance electrochemiluminescence for ultrasensitive FB1 sensing.

Accurate detection of Fumonisin B1 (FB1) is of great significance for food safety and disease prevention and control. In this work, the construction of dual metal-organic frameworks (MOFs) synergistically modulated electron transfer at the electrode interface, thereby enhancing ECL emission. This approach enabled ultrasensitive detection of fumo...

#8 [10.6] Proximity-inducible CRISPR/Cas13a trans-cleavage activity and hydrogel-assisted paper-based distance sensor for the detection of aflatoxin M1

#9 [9.7] A dual-functional Zn(II) metal-organic framework sensor for smartphone-assisted visual fluorescence detection of aniline and TMEDA in the vapor and aqueous medium

Aniline and N,N,N',N'-tetramethylethylenediamine (TMEDA), as key intermediates in organic synthesis, are widely used in pharmaceuticals, pesticides, and other fields. However, the pollutants pose significant threats to human health and ecosystems. Rapid and selective quantification of trace amine compounds in environmental samples remains a high...
