#1 [15.7] Specific detection against PSA by using emission wavelength of carbon dots modulates TiO(2)/In(2)S(3)-based photoelectrochemical aptasensor.

Sensitive and precise detection of prostate-specific antigen (PSA) is essential for the early diagnosis and monitoring of prostate cancer. However, conventional detection methods often suffer from limited sensitivity, poor selectivity, highlighting the need for advanced sensing platforms. Photoelectrochemical (PEC) biosensing achieve for PSA acc...

#2 [13.3] DNA Tetrahedral Nanoprobes-Based Logic-Gated FRET Sensor for in Situ Analysis of Dual MicroRNAs in Extracellular Vesicles

Abstract Conventional analysis of extracellular vesicle (EV)-derived microRNAs relies on vesicle lysis and RNA extraction, which disrupt native vesicular structure and eliminate intravesicular molecular cargoes. Here, we report a rigid DNA tetrahedral nanoprobes-based logic-gated Förster resonance energy transfer (FRET) platform for in situ, am...

#3 [13.1] Aptamer-mediated portable SERS sensor based on bimetallic magnetic nanotubes for internal standard-calibrated detection of multi-target disease markers.

Accurate early screening for hepatocellular carcinoma (HCC) requires multi-target detection methods with high sensitivity and strong anti-interference capability. In this study, we developed an aptamer-mediated SERS sensing method based on bimetallic magnetic nanotubes for the simultaneous detection of HCC markers alpha-fetoprotein (AFP) and Gol...

#4 [13.0] In-Capillary Integrated CE-LIF Platform with Bioinformatics-Guided Exosome Capture and Isothermal Amplification for Ultrasensitive Multiplexed Detection of HCC-Derived Exosomal MicroRNAs

Abstract Exosomal microRNAs (Exo-miRNAs) are promising liquid-biopsy biomarkers for noninvasive cancer detection; yet due to their short length, low abundance, and high sequence homology, the determination of Exo-miRNAs suffers from insufficient sensitivity, limited multiplexing, and operational complexity, impeding their high-throughput clinica...

#5 [12.7] Precise Mutation Detection in Low-Abundance Tumor-Derived Extracellular Vesicles via Microfluidic Immunomagnetic Reversible Affinity Capture

Abstract Molecular diagnostic technologies based on liquid biopsy are increasingly vital for clinical tumor molecular profiling. Compared to highly fragmented and easily degradable cell-free DNA (cfDNA), extracellular vesicles (EVs) offer distinct advantages by protecting nucleic acids from degradation. Enrichment of tumor-derived EVs using spec...

#6 [12.3] Catalytic BiFeO3/g-C3N4 Heterojunction Nanosheets Coupled with DNAzyme/Low-Leakage Sequential DNA Circuit for Ultrasensitive Electrochemical Aptamer-Based Detection of Colorectal Cancer Exosomes.

Tumor-derived exosomes are promising circulating biomarkers for early colorectal cancer (CRC) diagnosis, yet their low abundance and the complexity of biological fluids demand sensing strategies with both stringent specificity and amplified signal output. Here, we report an ultrasensitive electrochemical aptasensor for SW620 cell-derived exosome...

#7 [12.3] CHAI-sEV: A Programmable Hairpin-Driven Cas9 Platform with AI Integration for Dual-Protein Profiling and Intelligent Classification of Tumor-Derived Small Extracellular Vesicles

Abstract Multiplexed protein profiling of tumor-derived small extracellular vesicles (TsEVs) requires signal-conversion strategies that are sensitive, low-background, and orthogonal. Collateral-cleavage CRISPR assays based on Cas12a or Cas13a provide efficient amplification but can compromise single-pot multitarget detection, whereas the sequenc...

#8 [12.1] AuPt bimetallic nanocatalyst-amplified luminol-dissolved oxygen electrochemiluminescence for interferon-γ immunosensing

Interferon-γ (IFN-γ) is a pivotal inflammatory cytokine whose abnormal expression is associated with autoimmune disorders, infectious diseases, and cancer. Herein, a signal-off electrochemiluminescence (ECL) immunosensor was developed by integrating catalytic signal amplification with oriented antibody immobilization. An amino-functionalized ver...

#9 [12.0] Conducting Polymer–Nanomaterial Hybrids for Cancer Diagnostics

Cancer continues to pose a major global burden because of the high incidence and mortality, underscoring the urgent need for innovative and highly sensitive diagnostic technologies. Conducting polymer–nanomaterial (CP–NM) hybrid biosensors have become promising platforms for cancer biomarker detection, integrating the redox-active and biocompati...

#10 [11.8] Oxygen vacancies-induced dual-interface modulation for TiO(2)/BiOI-based photoelectrochemical biosensor of urinary cancer markers.

Non-invasive urine-based cancer biomarker detection holds significant clinical value in cancer screening, treatment efficacy monitoring, recurrence warning, and auxiliary diagnosis. To address the issues of poor sensitivity and selectivity in photoelectrochemical (PEC) biosensing for the detection of cancer biomarkers in urine, oxygen vacancies ...
