#1 [24.3] 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 [22.5] 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 [19.9] 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 [17.8] 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 [17.8] 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 [17.8] 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 [14.5] Selection and validation of novel DNA aptamer panel co-specific to Plasmodium falciparum and Plasmodium ovale lactate dehydrogenase.

Malaria remains a major global health concern. The development of point-of-care diagnostic aptasensors could improve malaria detection, patient management, and eradication efforts. We selected and validated single-stranded DNA aptamers against Plasmodium falciparum lactate dehydrogenase (Pf-LDH), using systematic evolution of ligands by exponent...

#8 [14.0] 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...

#9 [13.7] Electrochemical DNA Biosensors Formed from Self-Assembled Monolayers of Thiolated DNA and Mercaptohexanol: What We Know About This Interface.

Alkanethiol self-assembled monolayers have dominated methods for forming nucleic acid-modified functional interfaces on gold nanoparticles and electrodes due to the ease and spontaneous nature of gold-sulfur bond formation. In particular, an interface composed of DNA modified with a thiol-terminated, 6-carbon linker connecting the oligonucleotid...

#10 [13.6] Multi-screening of beta-lactam antibiotics in milk based on Fe(3)O(4)@phage/bacteria system and aggregation induced emission luminogen.

BACKGROUND: For the previous rapid screening methods, antibody, molecularly imprinted polymer, aptamer and receptor are the usually used recognition reagents. It is well known that there are many antibiotic receptors on bacterial surface, so in theory the whole bacterium can be used as recognition reagent for screening of the specific antibiotic...
