#1 [28.9] A photocurrent polarity switching photoelectrochemical aptasensor based on Er-MOF nanosheets and methylene blue for high-performance determination of CA15-3.

BACKGROUND: Photoelectrochemical (PEC) biosensors have attracted increasing interest for tumor biomarker detection due to their intrinsic advantages. However, conventional PEC sensing strategies are typically based on unidirectional "signal-on" or "signal-off" modes, which are vulnerable to matrix interferences in complex biological samples and ...

#2 [18.1] Dual-readout aptasensor based on CRISPR/Cas12a and nanozyme for accurate detection of KIM-1 and its application in kidney transplant prognosis.

Kidney injury molecule-1 (KIM-1) has emerged as a pivotal prognostic biomarker for renal allograft function. However, its detection remains challenging due to sensitivity and accuracy limitations. An innovative biosensing platform synergizing aptamer recognition, CRISPR trans-cleavage and nanozyme amplification for dual-readout KIM-1 detection h...

#3 [15.2] Anti-CRISPR Protein Regulates CRISPR/Cas12a Fusogenic-Nanovesicle-Based Platform for Extracellular Vesicle-Encapsulated Non-Nucleic Acid Target In-Vesicle Detection.

The detection of non-nucleic acid targets encapsulated in extracellular vesicles (EVs) faces two major challenges: (1) difficulties in efficient isolation and the risk of content degradation, and (2) the low abundance of target molecules encapsulated in EVs always leads to failed signal transduction and inadequate output signal intensity. To ove...

#4 [14.8] Chirality-Induced Spin-Selective Transduction of Circularly Polarized Light for Polarization–Neurochemical Coupling

Circularly polarized light (CPL) provides a powerful optical degree of freedom for information encoding, yet most CPL-responsive systems rely on weak circular dichroism-based absorption and lack chemically amplified readout mechanisms. Here, we report a chirality-driven spin-photonic transduction platform in which CPL helicity is converted into ...

#5 [13.8] Target-Specific Recognition and Standardized Readout: A DNA Nanotransduction Strategy for Nanopore Exosome Sensing toward Clinical Applications.

Solid-state nanopores are powerful single-molecule sensing tools, but their reliance on direct translocation requires high analyte concentrations and complicates biochemical specificity. We propose a DNA nanotransduction strategy featuring target-specific molecular recognition and standardized electrical readout, converting complex vesicular inf...

#6 [13.8] NHAPL enables homogeneous detection of RNA-associated glycan signals.

GlycoRNAs, newly identified RNA molecules bearing glycan modifications on cell membranes, are implicated in cell communication and immune regulation. However, current methodological limitations impede a thorough elucidation of their biological roles and clinical significance. Here, we developed Nucleotides Hybridization and Aptamer-based Proximi...

#7 [13.7] Multidimensional Pathogen Fingerprinting via DNA Scaffold-Confined Enzymatic Synthesis of Silicon Quantum Dots.

Accurate and highly sensitive detection of pathogenic bacteria is essential to public health. Conventional biosensors often rely on bulk signal amplification, which suffers from diffusion-limited kinetics and high background signals. Herein, we present a programmable, surface-confined biosensing strategy that constructs a target-responsive nucle...

#8 [13.5] Functionalized carbon nanotube-assisted dual-mode CRISPR/Cas12a detection of hepatitis C virus via catalytic assembly circuit-driven Y-shaped dsDNA activators.

Hepatitis C virus (HCV) is a major etiological agent of liver diseases and remains a serious global health threat. Herein, we report a dual-modal HCV biosensing platform for ultrasensitive HCV RNA detection by integrating near-infrared fluorescence and colorimetric readouts. In this system, the presence of HCV RNA initiates a catalytic assembly ...

#9 [13.3] Ultrasensitive dual-detection of antibiotics in animal-derived foods by nucleic acid signal amplification-assisted magnetic dispersive solid-phase extraction.

BACKGROUND: The presence of diverse residual trace antibiotics in various food matrices may accumulate in the human body through the food chain and potentially pose a significant risk to human health through synergistic effects. Consequently, the development of a sensitive method for the simultaneous detection of multiple antibiotics holds signi...

#10 [12.9] An Engineered Core-Satellite Magnetic Aptasensor with Built-In Calibration and Regeneration for Accurate Quantification of Oral Cancer Exosomes.

Exosomes carry diverse biologically active substances that can be transferred between cells, thereby influencing physiological and pathological states of the organism. Abnormal exosome levels are closely associated with cancer. Consequently, the precise detection of exosomes holds considerable importance for noninvasive cancer diagnosis and moni...
