#1 [26.8] Dual-mode PEC-colorimetric aptasensor for sensitive aflatoxin B1 detection via a BiVO(4)/Ni(3)(HHTP)(2) heterojunction and PdAuCu nanoenzyme amplification.

Rapid, sensitive, and accurate detection of aflatoxin B1 (AFB1) is essential for ensuring food safety. In this study, we developed a dual-mode photoelectrochemical-colorimetric (PEC-CL) aptasensor for AFB1 detection constructed from a BiVO4/Ni3(HHTP)2 type-II heterojunction integrated with a PdAuCu (PAC) ternary alloy nanoenzyme. The BiVO4/Ni3(H...

#2 [26.8] Artificial neural network data fusion-mediated dual-mode sensor based on Fe(3)O(4)@PdIr for Salmonellatyphimurium detection in food.

Salmonella Typhimurium (S. typhimurium) is a major foodborne pathogen that poses a serious threat to public health. In this study, a colorimetric/electrochemical dual-mode biosensor assisted by artificial neural network (ANN) was developed for the sensitive detection of S. typhimurium. Fe3O4@PdIr nanocomposites with enhanced peroxidase-like acti...

#3 [26.4] Near-Infrared Imaging of H(2)O(2) in Plants With Nanosensors Under Environmentally Changing Conditions.

Optical sensors are powerful tools to monitor biological systems. However, their practical deployment is often limited by environmental interferences such as autofluorescence, mechanical motion, and fluctuating illumination. These challenges are particularly pronounced in plants because they require and use light, which has impaired the use of (...

#4 [15.6] A bifunctional triblock zwitterionic copolymer combined with gold nanostars for antifouling electrochemical aptasensor to detect chloramphenicol in food samples.

To address the issue of electrochemical sensors being susceptible to fouling interference in complex food matrices, this work proposed a high-performance antifouling aptasensor based on a triblock zwitterionic copolymer and a gold nanostars (Au NSs) conductive substrate. Through precise control over the composition of two zwitterionic monomers [...

#5 [14.0] Amplifying the invisible: Liquid crystal-hydrogel microcavities decode trace Hg ions and aflatoxin B1.

Chinese herbal medicines (CHMs) have been applied to the prevention and treatment of numerous diseases. Ensuring the safety and pharmacological efficacy of CHMs demands precise detection of trace heavy metal ions and toxins, especially Hg and aflatoxin B1 (AFB1). However, due to subtle chemical signals, current technologies still make it challen...

#6 [13.6] A PMS-enhanced self-powered photoelectrochemical sensor based on dual-photoelectrode architecture for sensitive detection of carbofuran and acetamiprid.

A novel self-powered photoelectrochemical sensing platform was fabricated for the determination of acetamiprid and carbofuran. Donor-acceptor covalent organic frameworks were utilized as photoanode materials, while CuBr, with superior photochemical properties, served as the photocathode. The conjugated microporous structure of COFs accelerates p...

#7 [13.6] Bimetallic synergy and aggregation-induced emission enhanced electrochemiluminescence aptasensor for detection of aflatoxin B1.

Aflatoxin B1 (AFB1), a highly carcinogenic mycotoxin widely contaminating agricultural products, poses a severe threat to food safety and human health, thereby necessitating the development of detection methods. Electrochemiluminescence (ECL) has emerged as an ideal analytical technique due to its near-zero background and exceptional sensitivity...

#8 [13.6] Re-selection of DNA aptamers for acetamiprid for light-up fluorescent detection.

Acetamiprid is currently the only member of second-generation neonicotinoid insecticides permitted for open-field use within the European Union following the ban of other neonicotinoids. Its potential environmental and health risks underscore the need for reliable detection methods. Although an acetamiprid aptamer was previously reported, its wi...

#9 [13.6] Rational design of bispecific aptamers with high stability and affinity.

Bispecific aptamers (BsApts) enable dual-target recognition, which is essential for rapid antibiotic detection. However, the practical application of BsApts is often hindered by structural instability, which compromises their binding affinity. To address this, we employed a "sequence-structure-dynamic simulation" framework to design BsApts targe...

#10 [13.6] A multifunctional aptamer-based lateral flow assays with trimetallic nanozymes for the rapid detection of deoxynivalenol in maize.

BACKGROUND: Currently, aptamer-based lateral flow assays (LFAs) possess prominent merits of facile operation and cost-effectiveness, presenting potential application prospects in the realm of rapid food safety testing. However, it suffers from low accuracy and sensitivity in detecting mycotoxins in grains. RESULTS: This study developed a multifu...
