#1 [16.2] Hydrovoltaic-photoelectric coupling effect boosted self-powered aptasensor for on-site and ultrasensitive monitoring of enrofloxacin in aquaculture products based on CdS/ZIF-67 heterojunctions.

On-site monitoring of antibiotic residues in aquaculture products is of great significance for providing instant content information to protect food safety and human health. In this work, a novel hydrovoltaic self-powered electrochemical sensor was fabricated for real-time sensitive detection of enrofloxacin (ENR) by integration of photoelectric...

#2 [14.1] A one-step electrochemical strategy for rapid exosome detection using Cu(2+)-coordinated DNA nanoparticles.

Stimulus-responsive nucleic acid nanomaterials are attractive for label-free electrochemical biosensing because their programmable structures enable target-triggered signal generation in homogeneous systems. Herein, we report a one-step electrochemical strategy for rapid and highly sensitive detection of ovarian cancer (OC)-derived exosomes base...

#3 [14.1] Heteroaptamer recognition mediated strand displacement amplification for efficient electrochemical analysis of beta-2-microglobulin in breast milk.

The human milk protein beta-2-microglobulin (B2M) plays a vital role as a diagnostic biomarker for infants, with conventional detection methods frequently relying on intricate instruments that have constraints in sensitivity and selectivity. Here, an innovative heteroaptamer recognition-mediated strand displacement amplification for electrochemi...

#4 [14.0] An Integrated DNA Nanoprobe for Intranuclear Imaging and in Situ Profiling of OGG1 Activity.

Accurate quantification of 8-oxoguanine DNA glycosylase-1 (OGG1) activity in the cell nucleus is crucial for evaluating the DNA oxidative damage marker 8-oxoguanine (8-oxoG). However, due to the difficulty in nuclear localization and the predicament of strong signal output, subcellular imaging has not yet been achieved. Herein, we report a nucle...

#5 [13.7] Photothermal Recycling Biosensing for Continuous, Sensitive Molecular Quantification

Continuous biochemical sensing provides valuable insights into an individual’s physiological state and the mechanisms underlying pathophysiological changes. However, most existing bioanalytical methods are not compatible with continuous biochemical sensing. A major technical challenge lies in achieving rapid measurement readouts while maintainin...

#6 [13.3] DNA Tetrahedron-Mediated Sensing Platform on a Single Gold Nanowire: Special Signal Amplification, Self-Referencing Capability, and Cross-Validated Exosome Detection for Liver Cancer Liquid Biopsy.

Exosomes have emerged as promising biomarkers for noninvasive cancer diagnosis, while highly sensitive, reliable, and convenient assays remain challenging, particularly with conventional single-signal approaches. Herein, we report an exosome-tailored dual-mode self-referencing biosensing platform on a single gold nanowire (AuNW) substrate for th...

#7 [13.3] Development of a Core−Shell-Encapsulated Biosensor for On-Site Detection of Trace Chlorpyrifos

Chlorpyrifos, a broad-spectrum organophosphorus pesticide, accumulates persistently in the environment and food chain, posing significant risks to ecosystems and human health. Whole-cell biosensors offer a promising alternative for on-site pesticide detection. However, their practical application is hindered by insufficient sensitivity for trace...

#8 [13.3] Accurate Phenotyping at the Single-Exosome Level Using a Proximity-Ligation RCA-Based Light-Scattering Counting Platform for Breast Cancer Diagnosis.

Tumor-derived exosomes (TEXs), carrying rich proteomic information, have shown great promise as noninvasive biomarkers for cancer detection. However, their inherent heterogeneity, relatively low abundance, and significant interference from non-TEXs in biological fluids pose considerable challenges for accurate and sensitive TEX quantification. T...

#9 [13.3] Matrix-Boosted Electrochemiluminescence Biosensor for Ultrasensitive Exosome Detection and Automated Phenotype Discrimination.

Accurate quantification and phenotypic discrimination of exosomes in complex biological fluids remain technically challenging sensing issues, yet they are essential for early cancer diagnosis. To address this challenge, an ultrasensitive electrochemiluminescence (ECL) biosensor is engineered by integrating a "matrix-boosted" Cp-Pt-Ti3-xC2Ty MXen...

#10 [13.2] A 3D-Printed Scaffolded Hydrogel Microneedle Array Biosensor for Real-Time, Continuous Monitoring.

Hydrogel-based biosensors offer a promising platform for designing microneedles capable of continuously tracking biomarkers in real time. However, such biosensors have been limited by the mechanical properties of hydrated hydrogels, which are generally ineffective at penetrating the skin to access interstitial fluid (ISF). As a solution, we have...
