#1 [26.3] 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 [...

#2 [16.9] 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 [16.6] 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 [13.7] 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 ...

#5 [13.6] Digitally Printed Gold Nanoelectronics for Tap-to-Detect Electrochemical Biosensing and Chemical Sensing.

Printed electrochemical sensors offer a promising route toward decentralized diagnostics and environmental monitoring, but their practical use remains constrained by complex electrode fabrication and instrument-dependent readout. Here, we present a tap-to-detect sensing platform that couples digitally printed gold nanoparticle nanoelectronics wi...

#6 [13.3] PK-Tracker: A Real-Time Bedside Device for Continuous Therapeutic Drug Monitoring.

Medical procedures often require the administration of drugs, whose dosing is typically guided by pharmacodynamic responses rather than direct measurement of concentrations. This limitation largely arises from traditional monitoring procedures that rely on repeated venous sampling followed by laboratory analyses using cumbersome and costly instr...

#7 [13.3] Oxygen vacancy-amplified photoelectrochemical sensing of 8-oxo-guanine DNA glycosylase using Bi(6)S(2)O(15) nanowires.

8-Oxo-guanine DNA glycosylase (OGG) repairs oxidatively damaged DNA and correlates with various diseases, and sensitive OGG detection is vital for clinical diagnosis. Traditional detection methods have inherent drawbacks, including radiation risk and complicated preparation. Herein, a new photoelectrochemical (PEC) biosensor based on hydrotherma...

#8 [13.0] Cryo-Engineered DNA Cryogels with Interconnected Macroporous Architectures for Enhanced Mass Transfer and Ultrasensitive cTnI Detection via an Integrated Microfluidic Platform

Abstract Cardiac Troponin I (cTnI) is a definitive clinical biomarker for the diagnosis of acute myocardial infarction (AMI). Thus, its rapid and precise quantification is of paramount significance for clinical intervention. DNA hydrogels represent a premier choice for constructing rapid detection platforms due to their excellent target responsi...

#9 [12.6] Integrated Antigen–DNA Co‐Detection Using Digital Microfluidics for Improving Diagnostic Accuracy in POCT Analysis

ABSTRACT Simultaneous detection of protein and nucleic acid (NA) provides complementary information essential for accurate analysis of complex samples. Conventional approaches for the analysis of protein and NA typically rely on separate workflows and instruments, limiting the reliability of point‐of‐care testing. Here, we present a digital micr...
