#1 [22.7] 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 [14.5] 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...

#3 [13.1] 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 ...

#4 [12.3] A Cascaded DNA Nanocircuit for Multi‐Signal‐Responsive Precision siRNA Delivery in Cancer Therapy

Precision control over nucleic acid delivery remains a critical challenge in cancer therapy, particularly for siRNA-based gene silencing, where off-target effects limit clinical translation. Herein, we report a programmably engineered DNA nanocircuit with cascaded dual-AND logic gates, which enables the development of a spatiotemporally controll...

#5 [12.2] Application of aptamer nucleic acid test strips in the detection of tumor markers for colorectal cancer.

At present, the detection methods of tumor markers rely on ELISA, gene sequencing, and other technologies. However, these methods require specialized equipment and technical personnel, and the low concentrations of early tumor markers limit their sensitivity. This study developed a method for detecting colorectal cancer tumour markers. It uses a...

#6 [12.1] Aptamer-functionalized terahertz metasensor for sensitive and specific determination of alpha-fetoprotein.

Alpha-fetoprotein (AFP) is a key serum biomarker for the early diagnosis of hepatocellular carcinoma (HCC). In this study, a dual-band terahertz (THz) metasurface sensor (metasensor) was developed and functionalized with computationally selected aptamers for sensitive and specific detection of AFP. A 1000-sequence ssDNA library was screened usin...

#7 [11.5] Cascade-coupled colorimetric-fluorescent dual-signal detection of EGFR-positive extracellular vesicles via bifunctional MOF@Pt nanozyme integrated with a CHA-CRISPR system.

Extracellular vesicle (EV)-based liquid biopsy holds great promise for glioma diagnosis, but its clinical translation remains hindered by inefficient isolation of disease-relevant EV subpopulations and insufficiently integrated signal validation. Herein, we develop a platform that integrates a bifunctional nanozyme system (phosphatase-like MOF a...

#8 [11.3] A Light-Controlled DNA Nanoclaw Machine: Integrated Multiplexed Recognition, Spatiotemporally Programmable Therapy, and Real-Time Electrochemical Signaling for Precision Receptor Regulation.

Cell membrane receptors are pivotal targets in precise therapeutics, yet their ubiquitous expression across tissues remains a fundamental barrier to achieving cell-specific intervention. To overcome the limitations of conventional monotargeting approaches, we developed a light-gated DNA nanoclaw machine (L-DNM) that integrates high-specificity r...

#9 [11.3] Advances in Extracellular Vesicle-Based Surface-Enhanced Raman Spectroscopy for Cancer Diagnosis

As a noninvasive liquid biopsy approach, extracellular vesicle (EV)-based detection offers significant advantages in reflecting real-time tumor dynamis and overcoming the limitations of conventional tissue biopsy. EVs, nanoscale vesicles secreted by cells, carry diverse biomolecules such as proteins and nucleic acids, playing key roles in tumor ...

#10 [11.2] 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...
