#1 [13.5] Complementary integration of highly sensitive aptasensor and portable hydrogel for colorimetric detection of dhurrin in sorghum based on enhanced laccase-like activity of CuCo-MOFs.

As a cyanogenic glycoside commonly found in grass family plants such as sorghum, dhurrin poses a serious threat to the food safety due to its hydrolysis product, hydrogen cyanide. But the equipment is expensive and the procedures complex, making it difficult to meet the demand for rapid on-site screening. This study develops a colorimetric aptas...

#2 [13.5] An antifouling electrochemical aptasensor engineered with zwitterionic terpolymer and gold nanostars for robust analysis of oxytetracycline in food.

Electrochemical sensors still suffer from challenges associated with interference caused by fouling in complex matrices. To address this issue, we designed a tailored high-performance antifouling sensor interface based on a thiol-terminated zwitterionic terpolymer, [P(MPC-CBMA-MAA)-SH, PMCM-SH], by fine-tuning the composition of two zwitterionic...

#3 [12.4] Smartphone-assisted paper-based colorimetric aptasensor for rapid detection of N-acetylneuraminic acid.

N-Acetylneuraminic acid (Neu5Ac) is a bioactive compound that supports health across all age groups and plays an irreplaceable physiological role in food fortification and disease prevention and control. Herein, N-acetylneuraminic acid-functionalized gold nanoparticles (Neu5Ac-AuNPs) signal probes with peroxidase-like catalytic activity were syn...

#4 [12.3] Microfluidic Electrochemical Immunosensor Based on High-Entropy Oxide Nanozymes for On-Site Determination of Meat Authenticity

Abstract Meat adulteration poses severe risks to food safety, demanding rapid, portable, and sensitive detection methods for meat authenticity verification. Herein, a microfluidic electrochemical immunosensor was developed for on-site detection of pork adulteration in beef and lamb. Spinel high-entropy oxide (HEO) nanozymes with intrinsic peroxi...

#5 [12.2] CRISPR/Cas12a-Based Aptasensor for Cas9 Protein Detection in Spiked Food Matrices

Residual gene editors are a concern associated with the widespread application of CRISPR/Cas9 technology. Here, we developed a CRISPR/Cas12a-based fluorescent aptasensor for the qualitative and quantitative detection of Cas9 protein. Secondary structure prediction and molecular docking were combined to identify potential binding sites of the Cas...

#6 [12.1] 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...

#7 [11.8] 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...

#8 [11.3] 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...

#9 [10.1] A RCA-based signal amplification and machine learning-assisted sandwich-type dual-mode split aptamers sensor for the simultaneous detection of diarrhetic shellfish toxins.

Sensitive detection of diarrhetic shellfish toxins (DSTs) is vital for ensuring marine food safety. In this study, a novel sandwich-type dual-mode split aptamers sensor (DMSAS) was constructed for the ultrasensitive simultaneous detection of DSTs by integrating rolling circle amplification (RCA)-based signal enhancement, fluorescent/colorimetric...

#10 [10.0] 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...
