#1 [19.4] 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 [14.7] Phosphate‐Engineered DNA Reporters Boost CRISPR‐Cas12a Trans ‐Cleavage for Rapid and Sensitive Nucleic Acid Detection

ABSTRACT CRISPR–Cas12a molecular diagnostics rely on target‐activated collateral cleavage of single‐stranded DNA (ssDNA) reporters to generate fluorescence signals, yet the mechanisms governing reporter substrate processing remain poorly understood. Here we show that Cas12a trans ‐cleavage involves both endonucleolytic cleavage and exonucleolyti...

#3 [14.4] 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...

#4 [14.4] 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...

#5 [14.3] IMAN: An Integrated Colorimetric Sensor for Direct Detection of PD-L1 on Extracellular Vesicles in Lung Cancer Diagnosis.

Lung cancer is a leading cause of cancer mortality, yet early diagnosis remains difficult, highlighting the need for sensitive, noninvasive methods. Extracellular vesicles (EVs) and their surface proteins (e.g., PD-L1) are promising biomarkers; nevertheless, current EV detection requires time-consuming purification, sophisticated instrumentation...

#6 [14.1] 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...

#7 [13.8] 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...

#8 [13.7] Scaffold RNA Reengineering for a Leakage‐Suppressed CRISPR/Cas12a Cascade System Toward Precise Nucleic Acid Diagnostics

ABSTRACT Amplification‐free CRISPR detection has attracted significant attention for its capacity to circumvent the intricacies of nucleic acid amplification. Yet, the persistent challenge of high background signals remains a critical bottleneck, motivating intensive efforts toward background suppression strategies. Here, we present a 3’‐end DNA...

#9 [13.3] A DNA Logic-Gated Cascade Amplification Biosensor for Highly Specific Electrochemical Detection of Circulating Tumor Cells.

Circulating tumor cells (CTCs) are rare cancer-derived cells in peripheral blood, carrying vital information about tumor heterogeneity and progression. Their reliable detection remains challenging due to extreme rarity and high background interference. Herein, we report an electrochemical biosensor that integrates a DNA-based AND logic gate with...

#10 [13.2] Selection of a high-affinity DNA aptamer for puerarin and its application in fluorescence sensing.

Puerarin (Pue), a naturally occurring isoflavone, is an important quality marker of Pueraria lobata, a widely used traditional Chinese medicinal material. Reliable determination of Pue is therefore relevant to both pharmaceutical quality control and studies of its biological activity. Here, a library-immobilized capture-SELEX protocol was used t...
