#1 [23.5] 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 [...

#2 [16.2] Triple quenching strategy-based highly sensitive electrochemiluminescence sensor for perfluorooctanoic acid.

Quenching-based electrochemiluminescence (ECL) sensing boasts prominent advantages for trace analysis, while single-mechanism systems have inherent flaws, making the development of efficient synergistic quenching strategies of great practical significance for ultra-trace perfluorooctanoic acid (PFOA) detection. In this work, a zinc-coordinated p...

#3 [15.9] A dual-aptamer colorimetric sensor based on Cu-MOF@PtPdNPs for the highly sensitive detection of MUC1.

The abnormally high expression of MUC1 in various malignant tumors makes it a crucial biomarker for early cancer diagnosis. This study synthesized a Cu-MOF@PtPdNPs nanocomposite exhibiting robust peroxidase-like activity via an in-situ reduction method. By integrating this nanomaterial with a dual-aptamer recognition sandwich strategy, an effici...

#4 [14.8] An Integrated Cascade-Amplified Microfluidic Biosensor for Reconfigurable Profiling of CRC-Associated Faecal Extracellular Vesicle Surface Proteins.

Faecal extracellular vesicles (EVs) provide disease-relevant molecular information for non-invasive colorectal cancer (CRC) analysis. However, sensitive EV surface protein profiling remains challenging because low-abundance targets are obscured by heterogeneous vesicles and complex matrices. Here, an integrated cascade-amplified microfluidic bio...

#5 [14.6] G4All: a database of experimentally confirmed G-quadruplex-forming sequences.

G-quadruplexes (G4s) are non-canonical nucleic acid structures with critical roles in gene regulation, genomic stability, and disease, making them prime targets for therapeutic and biotechnological applications. However, the absence of a curated, centralized, experimentally validated repository of short (mostly synthetic) G4-forming sequences, p...

#6 [14.5] Aptamer-Functionalized Pro-Photosensitizers for Targeted Elimination of Drug-Resistant Bacterial Biofilm Infection by Sequentially Activated Photodynamic-Antibiotic Therapy.

Drug-resistant bacterial infections seriously threaten public health, and the formation of a biofilm barrier plays an important role. Drug-resistant biofilms are difficult to remove because the penetration and specificity of traditional antimicrobial drugs are poor, and the microenvironment in the inner layer of biofilms is hypoxic. Herein, we d...

#7 [14.3] Engineering a Reconfigurable Transmembrane Receptor Enables Logic-Controlled Signal Translocation.

Transmembrane receptors relay extracellular cues into intracellular responses through reconfigurable conformational changes, yet engineering synthetic systems that emulate receptor-like signal translocation with programmable control remains challenging. Here, we engineer a reconfigurable transmembrane receptor that enables logic-controlled signa...

#8 [14.2] A Bispecific Nanobridge Derived from Immunogenic Tumor Membranes Restores Dendritic Cell-T Cell Crosstalk for Enhanced Solid Tumor Immunotherapy.

In solid tumors, communication between dendritic cells (DCs) and T cells is impaired by poor immune infiltration and lack of physical contact, limiting current immunotherapies. Here, we develop a bispecific immune-bridging platform (NVMB) to address these limitations. NVMB consists of tumor cell membrane-derived nanovesicles enriched with damage...

#9 [13.7] Electrochemical Aptamer-Based Sensors Supporting Real-Time, Seconds-Resolved, Molecular Measurements in Awake, Behaving Rats.

The real-time, in vivo measurement of drugs, metabolites, and biomarkers in awake animals could enable unprecedented insights into metabolic regulation, pharmacokinetics, pharmacodynamics, and behavioral response. In pursuit of this vision, here we demonstrate a subcutaneous electrochemical aptamer-based (EAB) sensor architecture that (i) suppor...

#10 [13.3] A Practical Guide of Choosing and Validating Aptamers for Biosensors.

Aptamers have been reported for hundreds of targets, and for many important analytes, multiple independent selections have yielded distinct sequences. Subsequent truncation, mutation, and chemical modification have further generated numerous variants of the original aptamers. This rapidly expanding sequence space, however, has created a growing ...
