#1 [22.9] Unconventional DNA architecture in a dopamine–bound aptamer complex

Abstract Aptamers are oligonucleotides that have been selected to bind a particular target. Despite the growing popularity of functional DNA aptamers, there remains limited knowledge of their binding mechanisms, as few have been characterized at the atomic level. Here, we use NMR spectroscopy to obtain structural details of RKEC1, a shortened ve...

#2 [21.4] 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 (...

#3 [20.4] 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...

#4 [20.4] 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...

#5 [20.4] 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...

#6 [19.8] 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...

#7 [19.8] 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...

#8 [14.8] Dual DNA Nanomaterial-Regulated Homogeneous Immunoreaction-Enabled One-Step Electrochemical Analysis of Multiple Biomarkers in Clinical Samples

Abstract Homogeneous immunoassays offer a streamlined alternative to traditional heterogeneous methods by eliminating separation and washing steps. However, they are often hampered by low sensitivity, matrix interference, and limited multiplexing capability. Herein, we reported a dual DNA nanomaterial-based homogeneous electrochemical immunoassa...

#9 [13.3] 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 [...

#10 [12.8] A Pt@Z8P-based electrochemiluminescence aptasensor with T7 exonuclease-assisted amplification for ultrasensitive deoxynivalenol determination in cereals.

Deoxynivalenol (DON) is among the most prevalent trichothecene mycotoxins in cereals and cereal-derived foods. Chronic low-level exposure to DON continues to pose health and economic risks. Herein, an electrochemiluminescence (ECL) aptasensor was developed from a dual-ligand ZIF-8-derived emitter (Pt@Z8P) integrated with T7 exonuclease (T7 EXO)-...
