#1 [33.5] Self-powered photoelectrochemical aptasensor based on CHA-triggered G-quadruplex/hemin cascade for homogeneous detection of ochratoxin A in a separated-coupling electrolysis system.

To address the challenge of electroactive interferences derived from complex food matrices during homogeneous photoelectrochemical (PEC) biosensing, a "separated-coupling" electrolysis platform was rationally engineered for the ultrasensitive detection of ochratoxin A (OTA). Based on the analysis of the conduction band of the α-Fe2O3 photoanode ...

#2 [31.6] A novel triple-mode sensor utilizing trimetallic derived fluorescent carbon dots nanozyme for tetracycline determination.

Tetracycline (TC) is notoriously resistant to degradation in natural environments, which contributes to its prolonged persistence and widespread contamination. Improper or excessive use of TC can lead to multifaceted hazards. In this study, we developed a trimetallic-doped carbon dots (Fe,Cu,Ce-CDs)-based composite that exhibits distinct fluores...

#3 [28.9] Electrochemically covalent lock stabilizes aptamer conformation and strengthens its sensing performance for PFOA.

PER: and polyfluoroalkyl substances (PFAS) are widely detected emerging pollutants, yet their accurate identification in complex water remains a major challenge. Herein, we developed an innovative aptamer (Apt) -based electrochemical molecularly imprinted polymer (MIP) sensor for high-sensitivity detection of perfluorooctanoic acid (PFOA) in com...

#4 [26.6] From rational engineering of a broad-spectrum aptamer to multi-residue screening: A fluorescent aptasensor for multiplexed sulfonamides.

The increasing prevalence of multiple antibiotic residues in animal-derived foods presents significant challenges for monitoring efforts. Broad-spectrum aptamers offer great promise for enabling multiplex detection of various antibiotic residues. However, aptamers directly screened for this purpose often exhibit low affinity and poor stability, ...

#5 [26.6] Nanomaterial-enabled CRISPR-Cas biosensing for non-nucleic acid targets: Strategies, mechanisms, and applications.

Nanomaterial-assisted CRISPR-Cas biosensing has transcended nucleic acid detection, emerging as a prominent paradigm for the ultrasensitive analysis of non-nucleic acid targets. This review systematically elucidates recent advances by proposing a novel three-dimensional framework encompassing transduction efficiency, signal output, and applicati...

#6 [26.6] A bimetallic metal-organic framework-based aptasensor for dual-mode colorimetric and fluorescent detection of Fumonisin B(1).

Fumonisin B1 (FB1) is a secondary metabolite produced by Fusarium species and is considered one of the most dangerous mycotoxins. It is widely present in maize and other agricultural commodities, posing severe threats to human health and animal husbandry. Consequently, the development of a convenient and rapid detection method is of paramount im...

#7 [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...

#8 [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...

#9 [14.5] Double-target responsive FRET sensor based on DNA tetrahedron for robust detection of liver fibrosis-related mRNAs in activated hepatic stellate cells.

Early diagnosis and graded evaluation of liver fibrosis remained challenging due to the limited sensitivity and accuracy of current noninvasive diagnostic tools. The imaging strategy of intracellular disease-related biomarker based on DNA nanoparticles had been used for accurate diagnosis and prognosis studies. However, their sensitivity and acc...

#10 [13.5] Rational design of Cr(VI) aptamer guided by revealed cation-mediated binding mechanism and construction of a label-free fluorescent aptasensor.

Aptasensors are widely recognized as practical and rapid detection tools for heavy metal pollution due to their high specificity and sensitivity. However, screening aptamers for small molecules (including ions) is significantly challenging. To date, only two Cr(VI) aptamers have been reported, which cannot meet the demand of aptasensor developme...
