#1 [13.5] CuCo alloy-embedded carbon nanocages for simultaneous biosensing of Hg(2+) and Cd(2+) in environmental water.

Mercury ions (Hg2+) and cadmium ions (Cd2+) are highly toxic heavy metals that can easily accumulate in the food chain and pose serious threats to the environment. However, achieving sensitive and efficient identification and determination of trace Hg2+ and Cd2+ remain a major challenge in real water environment. In this work, we developed an ul...

#2 [13.1] pH-switchable multi-enzyme-like activities of Bi(12)Co(0.6)O(18.8)-AuNPs nanozyme: An electrochemical-colorimetric dual-mode aptasensor for ultrasensitive Cd(2+) detection in rice.

The severe health risks associated with cadmium-contaminated food necessitate the development of accurate and rapid detection technologies. Herein, a novel pH-switchable multi-enzyme activity Bi12Co0.6O18.8-AuNPs is designed to construct a dual-mode aptasensor for the rapid and reliable detection of Cd2+. This nanozyme exhibits pH-modulated cata...

#3 [12.6] A dual-mode fluorescence-electrochemistry aptasensor based on a bifunctional nanoprobe and a target-induced dissociation strategy toward tetracycline analysis.

The excessive use of tetracycline (TC) poses significant health risks to humans. Here, a dual-mode fluorescence-electrochemistry biosensor is developed based on a COF/AuNPs/MB bifunctional nanoprobe and a TC-induced dissociation strategy. This biosensor simplifies fabrication, avoids electrode modification, and achieves excellent applicability i...

#4 [11.3] Orthogonal Stimuli-Responsive Y-Shaped DNA Probe for Dual-Antibiotic Photoelectrochemical Detection

Abstract Simultaneously recognizing multiple targets and independently decoding their signals in food is critically demanded for safeguarding public health against antimicrobial resistance. Photoelectrochemical (PEC) sensors, promising for on-site detection, face a fundamental constraint: all targets generate unidimensional current signals at th...

#5 [11.3] Zein-templated synthesis of Au@Pt bimetallic nanozymes: a multi-mode lateral flow immunoassay platform for ultrasensitive colorimetric and fluorometric detection of tetracycline in food.

The systematic development of a multifunctional zein-stabilized Au@Pt bimetallic nanozyme (zein-Au@Pt) for highly efficient multimodal detection of tetracycline (TC) is described. We created a core-shell nanostructure using zein protein as a biomimetic template, combining the Au@Pt bimetallic interface's high peroxidase-mimicking activity with t...

#6 [11.3] Hollow AIEzymes-engineered three-mode sensing platform for ultrasensitive and reliable detection of ochratoxin A

To improve detection accuracy, there is an urgent need to develop multimodal sensing methods for target pollutants. Given the broad prospects of aggregation-induced emission (AIE) agents in fluorescence and electrochemiluminescence (ECL) detection, endowing AIE agents with molecular recognition capabilities, such as enzyme-like activity, is of g...

#7 [11.3] A Collective CRISPR-Cas12a Biosensing Platform for Effect-Based Screening of Pesticide Residues

The simultaneous screening of multicomponent pesticide residues, rather than a single specific compound, remains a critical yet challenging frontier in safety surveillance, largely due to the inherent one-to-one recognition bottleneck in conventional aptamer- or antibody-based biosensors. Herein, we develop a collective CRISPR-Cas12a biosensing ...

#8 [11.2] Group detection of phthalates from mulches: Two competitive aptamer-based electrochemical approaches.

Phthalates, known as endocrine disruptors, are often contained in plastic-based materials and may enter food webs, threatening human health. In this study, an oligonucleotide-based competitive assay for phthalates detection was built on an electrochemical platform, based on poly(l-glutamic acid) and gold nanoparticles. Different assay formats we...

#9 [11.2] An electrochemical aptasensor based on PtPd NPs/g-C(3)N(4) and a locked DNAzyme amplification strategy for ultrasensitive ATP detection.

Adenosine triphosphate (ATP) is a widely recognized indicator of microbial contamination, and its rapid and accurate detection is essential for assessing microbial pollution in food safety. Herein, an electrochemical aptasensor integrating a dual-signal amplification strategy was developed for ultrasensitive detection of ATP. Platinum-palladium/...

#10 [11.1] MCOF-assisted and MnO(2) nanozyme-triggered cascade dual-mode aptasensor for intelligent detection of Salmonella Typhimurium.

Conventional methods for detecting Salmonella Typhimurium in food often require lengthy procedures or specialized instrumentation. We developed a dual-mode aptasensor based on magnetic covalent organic frameworks (MCOFs) and MnO2 nanozymes. MCOF-AuNPs@apt captures bacteria, followed by MnO2@apt binding to form sandwich complexes. The retained Mn...
