#1 [19.6] 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 [18.2] 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 [16.1] 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 [15.2] 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 [14.2] Electropolymerized Aptasensor for Femtogram-Level Cytokine Detection.

Detecting cytokines at ultralow concentrations is important for the early diagnosis and monitoring of inflammatory and immune disorders, yet remains constrained by the sensitivity and stability of bioelectronic interfaces. Here, we present an electropolymerization strategy for preparing poly(amino-ʟ-tyrosine) (pALT) nanofilms as functional bioin...

#6 [14.1] Biomaterials Meet Organic Electrochemical Transistors: Materials, Interfaces, and Biosensing Frontiers

ABSTRACT Organic electrochemical transistors (OECTs) are emerging as powerful biosensing platforms, offering high transduction efficiency, low‐voltage operation, and intrinsic compatibility with aqueous and physiological environments. Central to their recent progress is the strategic integration of biomaterials, which govern interfacial charge t...

#7 [13.6] Antibodies and aptamers as affinity ligands for exosome isolation, detection, and targeted delivery: A review.

Exosomes, key mediators of intercellular communication, are emerging as promising tools for disease diagnosis and therapy. Realizing this potential depends on technologies that can isolate, detect, and deliver exosomes with high specificity and efficiency. Affinity-based strategies that exploit the molecular recognition of antibodies and aptamer...

#8 [13.5] Enzyme-free dual-hotspot SERS immunosensor via cascaded boronate assembly

The precise detection of CA19-9 is paramount for early cancer diagnosis and clinical monitoring. However, traditional immunoassays are often hampered by their heavy reliance on matched antibody pairs and the insufficient sensitivity of enzymatic amplification systems. To address these limitations, we report a novel, enzyme-free surface-enhanced ...

#9 [13.0] Plasmon‐Driven Gene Amplification‐Integrated Lateral Flow Assay for Ultrafast Diagnosis of Seoul Orthohantavirus

Accurate and rapid nucleic acid detection is vital for the early diagnosis of infectious diseases. Conventional polymerase chain reaction (PCR) offers high sensitivity but is hindered by bulky equipment, long processing times, and the need for technical expertise, limiting its point-of-care testing (POCT) applications. To overcome these constrai...

#10 [12.8] Aptamer-Based Platforms for Human Aging Biomarkers: Multiplexed Proteomics, Biosensors and Translational Perspectives

Aptamer-based multiplexed proteomic platforms, especially the SOMAmer-based SomaScan assay, are widely used for large-scale discovery of circulating biomarkers relevant to human aging. This review summarizes 42 original research articles published from 2020 through 2026 in which aptamers or aptamer-derived biosensors were used to characterize ag...
