#1 [28.7] Hierarchical triple-mode immunosensing of aflatoxin B1: From visual screening to precise confirmation.

This work establishes a hierarchical triple-signal immunoassay based on a multifunctional nanocomposite of Prussian blue nanoparticle@carbon dot (PBNPs@CDs), aiming to address material complexity and system integration issues in multimodal sensing. PBNPs@CDs possess peroxidase-like activity, efficient photothermal conversion, and strong fluoresc...

#2 [26.1] A novel fluorescent aptasensor for sensitive and label-free detection of Di(2-ethylhexyl) phthalate based on catalytic hairpin assembly-assisted CRISPR/Cas9 and G-triplex.

Di(2-ethylhexyl) phthalate (DEHP) is a widely used plasticizer that poses significant risks to human health and ecosystems, making its sensitive, rapid, and reliable detection critically important for environmental monitoring and food safety assessment. CRISPR-Cas9, beyond its canonical site-specific endonuclease function, has recently been repo...

#3 [22.3] 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...

#4 [20.5] 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 (...

#5 [19.4] 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...

#6 [19.4] 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...

#7 [19.4] 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...

#8 [18.9] 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...

#9 [18.9] 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...

#10 [15.7] Bioengineered titanium implants functionalized with aptamer-valproic acid conjugates orchestrate macrophage programming and mesenchymal stem cell homing for improved osseointegration.

Conventional titanium implants often exhibit limited bioactivity, failing to adequately modulate the immune response and promote endogenous regeneration, which leads to suboptimal osseointegration. To address this, we developed a multifunctional implant (NTP/Apt-VPA) by conjugating Apt19s-an mesenchymal stem cell (MSC)-specific aptamer-with valp...
