#1 [13.6] A self-powered photoelectrochemical aptasensor based on core-shell Z-scheme Co(3)O(4)@ZnO/ZnO@Co(3)O(4) heterojunction and bimetallic zeolitic imidazolate framework-derived templates for ultrasensitive detection chlorpyrifos.

Pesticide residues pose a serious threat to food safety and public health, making the development of rapid and sensitive on-site detection technologies a major challenge. Here a self-powered photoelectrochemical aptasensor is reported for ultrasensitive detection of chlorpyrifos in food samples. The sensor is based on a Z-scheme Co3O4@ZnO/ZnO@Co...

#2 [13.2] A PMMA@Ti3C2Tx-Ag array-structured SERS platform for sensitive detection of pesticide residues on fruit surfaces

#3 [12.8] 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...

#4 [12.8] 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...

#5 [12.3] Detection of Isocarbophos Using Porous Silicon Bragg Mirror Combined with Upconversion-Nanoparticle-Based Fluorescence Imaging

To address the difficulty of simultaneously achieving low cost, high sensitivity, and rapid response in the detection of isocarbophos residues in agricultural products and environmental water samples, a portable fluorescence sensing platform integrating a porous silicon Bragg mirror (PSBM) and upconversion nanoparticles (UCNPs) was constructed i...

#6 [12.0] Construction of Fe(3)O(4)@Au-Based Fluorescence-Colorimetric Aptasensor for Acetamiprid Assay.

Acetamiprid (ACE) residues in vegetables from long-term pesticide use pose potential toxicity risks to human health. Therefore, simple and accurate methods for ACE detection are essential for food safety. In this study, a dual-mode aptasensor was developed based on the specific recognition of fluorescent aptamers (Apts-FAM) combined with the flu...

#7 [12.0] Aptamer-gated FRET nanosensor based on UCNPs-AuNSs for sensitive detection of methylmercury in seafood matrices.

Methylmercury (CH3Hg+) is the most toxic form of mercury found in fish, shellfish, and other aquatic organisms and poses significant risks to human health through the food chain. The present study reports the development of a fluorescence aptasensor for the quantification of CH3Hg+ using aptamer-functionalized gold nanostars (AuNSs) and compleme...

#8 [11.7] 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...

#9 [11.7] 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...

#10 [11.6] 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...
