#1 [19.5] 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 [18.4] 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...

#3 [17.8] 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...

#4 [15.3] 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...

#5 [14.8] Highly specific aptamer-based structure-switching sensor for detection of the smallest alkali metal ion Li(+) in serum.

Lithium carbonate, a frontline drug for bipolar disorder (BD), requires strict therapeutic drug monitoring (TDM) due to its narrow therapeutic window (0.6-1.2 mM). Existing methods like inductively coupled plasma mass spectrometry (ICP-MS) and ion-selective electrodes (ISE) struggle to balance point-of-care testing (POCT) demands with interferen...

#6 [14.8] In situ monitoring of ferroptosis via dual-mode imaging of TFR1 expression using an aptamer-engineered MOF-Ag nanohybrid.

Ferroptosis is closely associated with the cytotoxicity of foodborne contaminants, with Transferrin Receptor 1 (TFR1) serving as a critical biomarker. Consequently, the in situ dynamic monitoring of TFR1 is crucial for unraveling the toxicological mechanisms underlying foodborne toxicity. To address the challenges of interference and insufficien...

#7 [14.0] Self-Assembled Aptamer-Derived PROTAC Enables Efficient Cellular Internalization for Intracellular Sclerostin Degradation and Triple-Negative Breast Cancer Therapy.

Comprising an aptamer for protein of interest (POI) recognition, a linker, and an E3 ligand, aptamer-derived PROTAC enables precise intracellular POI degradation via ubiquitin-proteasome system. Due to hydrophilic polyanionic backbone, their efficacy was fundamentally constrained by inefficient cellular internalization. Here, we engineered a sel...

#8 [13.8] AuPt bimetallic nanocatalyst-amplified luminol-dissolved oxygen electrochemiluminescence for interferon-γ immunosensing

Interferon-γ (IFN-γ) is a pivotal inflammatory cytokine whose abnormal expression is associated with autoimmune disorders, infectious diseases, and cancer. Herein, a signal-off electrochemiluminescence (ECL) immunosensor was developed by integrating catalytic signal amplification with oriented antibody immobilization. An amino-functionalized ver...

#9 [13.6] Programmable Fc-encoded DNA tile-cube capture enables a thrombin-activated ratiometric ECL/SERS biosensor via a PAM-engineered toehold switch and CRISPR/Cas12a cleavage.

BACKGROUND: Accurate thrombin detection is important for coagulation-related assessment, but reliable quantification at ultralow levels remains challenging because matrix interference, electrode-to-electrode variation, and single-channel signal drift can compromise analytical accuracy. Herein, we developed a thrombin-responsive ratiometric elect...

#10 [13.5] 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, ...
