#1 [15.6] 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 [14.8] A dual-mode electrochemiluminescence/SERS biosensor for B-type natriuretic peptide based on a T7-CRISPR/Cas13a cascade and a CsPbBr(3)@PDA@Au perovskite interface.

B-type natriuretic peptide (BNP) is an important biomarker for cardiovascular diseases, motivating sensitive and robust quantification in complex matrices. Here we report a single-electrode, anti-correlated dual-mode electrochemiluminescence/surface-enhanced Raman scattering (ECL/SERS) biosensor that couples split-aptamer recognition with a solu...

#3 [13.8] Advancing point-of-care diagnostics: Engineering and enhancing sensitivity and specificity in nanoparticle-based lateral flow assays for rapid disease detection.

Lateral flow assay (LFA) is the most widely used point-of-care (PoC) diagnostic tools due to their simplicity, rapid turnaround, portability, and low cost. Despite their extensive adoption in clinical diagnostics, food safety, and environmental monitoring, conventional LFA remain limited by inadequate sensitivity, poor quantification, and restri...

#4 [13.8] Photoelectrochemical aptasensor for ultrasensitive detection of MUC1 based on titanium dioxide/polypyrrole/carboxy polyethylene glycol hybrid anti-fouling interface.

Achieving ultrasensitive detection of MUC1 in the early stages of breast cancer is critical for reducing mortality and improving patient prognoses. Photoelectrochemical sensing has emerged as a promising technology for the detection of MUC1, primarily due to its straightforward operation and user-friendly instrumentation. However, titanium dioxi...

#5 [13.8] Switch-type photoelectrochemical aptasensor for microplastics and nanoplastics detection based on two-dimensional organic-inorganic heterojunction.

Microplastics and nanoplastics (MNPs) as emerging pollutants present substantial risks to both the environment and human health. Developing highly sensitive methods to rapidly identify and detect low concentrations of MNPs in complex systems remains a considerable challenge. Here, an "off-on" switch-type photoelectrochemical (PEC) aptasensor was...

#6 [13.8] Ratiometric fluorescence aptasensor based on hollow mesoporous silica for gentamicin detection.

Gentamicin (GEN) is an aminoglycoside antibiotic widely used in animal husbandry because of its low cost and high therapeutic efficacy; however, its residues in milk pose a potential risk to food safety. In this study, a truncated aptamer (G41) with high affinity toward GEN was obtained through molecular docking and molecular dynamics simulation...

#7 [13.8] Organic electrochemical transistors (OECT) based biosensors for the detection of small molecule metabolites.

Recently, organic electrochemical transistors (OECTs) have emerged as robust platforms for chemical and biological sensing, due to their intrinsic signal amplification, biocompatibility, and low-voltage functionality. OECTs have exhibited tremendous promise for detecting small molecule metabolites (SMMs), which are crucial as biomarkers in medic...

#8 [13.8] A dual-mode sensing strategy for the detection of Malathion based on bimetallic nanozymes coupled with aptamers.

Malathion (MLT) is an organophosphate insecticide with well-defined toxicity to the human body. Both short-term exposure to high doses and long-term exposure to low doses can impair human health. In this study, we developed a novel colorimetric and photothermal method for the detection of MLT using aptamer (Apt)-conjugated FeCu-metal-organic fra...

#9 [13.8] A widely used CRP aptamer does not bind CRP, revealing a general route to surface-driven pseudoaffinity in biosensors

ABSTRACT Aptamer sequences are often reused in biosensors and diagnostics without independent confirmation of binding activity, even though rigorous validation requires quantitative solution-phase testing by orthogonal methods. Here, we re-examined a DNA sequence reported in 2010 to bind C-reactive protein (CRP) with a K d of 3.5 nM by surface p...

#10 [13.8] 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...
