#1 [31.6] Bifunctional DNA multivalent structure integrating stable capture of urothelial carcinoma cells with CRISPR/Cas12a signal amplification for bladder cancer detection.

Noninvasive detection of bladder cancer remains challenging due to the limited analytical performance of current urine-based assays under realistic detection conditions. Here, we report a linear programmable DNA nanostructure that integrates multivalent aptamer recognition with CRISPR/Cas12a signal transduction for detecting tumor-derived urinar...

#2 [30.1] Shell-thickness-modulated electrochemiluminescence of colloidal quantum dots for ultrasensitive PSA detection.

Electrochemiluminescence (ECL) biosensors hold great promise for clinical diagnostics, yet their performance is often constrained by the limited efficiency and stability of available luminophores in complex biological matrices. Colloidal quantum dots (QDs) have emerged as attractive alternatives to conventional emitters, but a systematic underst...

#3 [27.5] Integrated single-tube detection of miRNAs in subpopulation-specific extracellular vesicles via spatially colocalized dual-module DNA scaffold.

Extracellular vesicles (EVs)-derived miRNAs are valuable non-invasive biomarkers for early cancer diagnosis. However, most current methods detect either total EVs-miRNAs or those from a single subpopulation, overlooking subpopulation heterogeneity. Moreover, EVs isolation and miRNA analysis are often conducted in separate workflows, increasing s...

#4 [26.6] Steric hindrance effect synergizing hole-trapping technique: High-Stability and high-accuracy Si/CdS n-n heterojunction photoelectrochemical biosensing of amyloid-β42.

Due to rapid carrier recombination and photodegradation, cadmium sulfide (CdS), an n-type semiconductor photosensitive material, has a low utilization efficiency that restricts its use in biosensing. A synergistic hole-trapping approach utilizing steric hindrance effects is proposed in this paper. First, chemical bath deposition (CBD) is used to...

#5 [14.9] CRISPR RNA Engineering Enables Single Nucleotide Polymorphism Discrimination in Nucleic Acid Detection

ABSTRACT Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)‐based diagnostic systems have emerged as powerful platforms for sensitive nucleic acid detection, yet their clinical reliability is frequently constrained by off‐target activation and insufficient discrimination of closely related sequences. This review synthesizes curre...

#6 [14.5] Surface-confined CRISPR-Cas12a biosensor with metal-enhanced fluorescence for rapid and ultrasensitive detection of SARS-CoV-2 nucleocapsid protein.

CRISPR-Cas12a integrated with nanomaterials has formulated powerful biosensors for viral protein detection, addressing the urgent need for point-of-care diagnostics. However, existing platforms are hindered by either multi-step separation procedures or insufficient signal amplification, limiting their sensitivity and practicality. Here, we repor...

#7 [14.3] MetaboSense: An Integrated Quantum Dot-Mediated Aptamer Assay and Modular Microfluidic Platform for Continuous In-Line Monitoring of Lung Metabolism During Ex Vivo Perfusion.

Organ transplantation provides a life-saving intervention for patients with end-stage lung disease; however, access to this treatment remains limited by the shortage of donor organs. Ex vivo lung perfusion (EVLP) is a platform that enables surgeons to assess extended-criteria for donor lungs prior to transplantation and has safely expanded the d...

#8 [14.1] An innovative immobilization-free homogeneous electrochemical strategy facilitated by buoyancy -magnetism separation for evaluating the acetamiprid in food.

An innovative enzyme-free and immobilization-free homogeneous electrochemical sensing strategy mediated by buoyancy-magnetism separation cooperation with Fe3O4@Ag was designed for the sensitive detection of acetamiprid (ACE). This approach ingeniously integrates hollow silica microspheres (HSB) as suspension recognition units with Fe3O4@Ag as ma...

#9 [13.9] Harnessing Synergistic Enthalpy‐Entropy Regulation: An I‐Motif‐Based Modulating Design for Programming Stimulus‐Responsive DNA Switches

ABSTRACT DNA switches with target‐induced allostery show great potential in biomedical application, yet often remain unprogrammable responses and limited accuracy. Existing designs also lack adaptability beyond predefined response windows and offer limited sensitivity tuning. Herein, we present an i‐motif‐based modulating design that leverages e...

#10 [13.9] Harnessing Synergistic Enthalpy-Entropy Regulation: An I-Motif-Based Modulating Design for Programming Stimulus-Responsive DNA Switches.

DNA switches with target-induced allostery show great potential in biomedical application, yet often remain unprogrammable responses and limited accuracy. Existing designs also lack adaptability beyond predefined response windows and offer limited sensitivity tuning. Herein, we present an i-motif-based modulating design that leverages enthalpy-e...
