#1 [17.9] AptaStick: A 3D-printed aptamer-functionalized stir-stick for selective extraction of bisphenol A from soft drinks.

This work presents AptaStick, a stereolithography 3D-printed stir-stick device functionalized with a bisphenol A (BPA)-specific aptamer for selective extraction from soft drinks. For this purpose, several geometries were evaluated to optimize extraction performance, with a star-shaped design providing the highest extraction efficiency and reprod...

#2 [17.1] A PD-L1-targeted and lactate-responsive DNA hydrogel enabling Mito-US therapy: dual functions for postsurgical cancer detection and eradication.

The minimal residual disease (MRD) following tumor resection remains a major challenge for preventing recurrence. Existing treatments usually exhibit poor specificity for scattered tumor cells at the surgical site. Moreover, few strategies successfully combine real-time MRD monitoring with sustained therapeutic intervention, further limiting the...

#3 [16.0] Aptamer-cDNA-driven nanozyme strategy: A recyclable dual-signal immunosensor for amplified detection of aflatoxin B(1) in edible oil.

Aflatoxin B1 (AFB1) poses a serious threat to human health, highlighting theurgent need for sensitive, precise and visual detection methods in daily foods. However,traditional detection methods relying on peroxidase (POD)-mimetic activity are susceptible to external interference, which increases false-positive or false-negative rates and comprom...

#4 [15.8] Aptamer-integrated DNA tetrahedral sensors for cancer cell imaging and invasiveness assessment.

DNA tetrahedron is a nanoscale framework self-assembled from DNA strands. Their nucleic acid composition confers excellent biocompatibility, rendering them highly suitable for drug delivery and biomarker imaging applications. Aptamers are short oligonucleotides that bind target proteins with high affinity and specificity. Integration of multiple...

#5 [15.4] Fabrication of electrochemical biosensor with a CD36 aptamer and AuMoS(2) heterolayer for tumor-derived exosome detection.

Breast cancer (BC), which is often diagnosed at advanced stages owing to its asymptomatic progression, presents with substantial molecular heterogeneity, leading to diverse therapeutic responses and prognostic outcomes. Among its molecular subtypes, the human epidermal growth factor receptor 2-positive/hormone receptor-negative (HER2+/HR-) pheno...

#6 [14.1] Surface activation and functionalization with aryl-diazonium chemistry enable biomolecules grafting on 3D printed carbon-based electrodes.

Carbon-based electrodes printed using fused deposition modelling (FDM) technology constitute appealing platforms for electrochemical biosensors. However, immobilizing bioreceptors that retain their stability and recognition properties at the electrode surface is quite challenging. So far, only few successful biosensors based on covalently bindin...

#7 [13.8] Ligand-EngineeredMn-Cysteine as a Potent LaccaseMimic for CRISPR/Cas12a Electrochemical Biosensing of HepatocellularCarcinoma Biomarkers

Abstract Laccase is an environmentally friendly catalyst with water as the sole catalytic byproduct, yet its biomedical detection potential remains underexplored. Herein, a ligand engineering strategy was employed to synthesize Mn-cysteine nanoflowers (Mn-Cys NF) with laccase-mimicking activity via a one-pot method, using manganese (Mn) with ric...

#8 [13.7] Electrochemical Cytosensor with Dual-Site Recognition Fabricated by In Situ Catalase-Encapsulated Metal-Organic Frameworks for Isolation and Detection of Circulating Tumor Cells in Whole Blood.

Circulating tumor cells (CTCs) are critical biomarkers for cancer prognosis and treatment monitoring, yet their detection remains challenging due to low abundance and phenotypic heterogeneity. Herein, we developed a dual-aptamer-conjugated electrochemical cytosensor using an in situ catalase (CAT)-encapsulated nanozyme CAT@Fe(SS)MOF-EpCAM/MUC1 (...

#9 [13.7] FOCUS: A Dual-Mismatch crRNA Strategy Unlocks High-Fidelity One-Step SNV Detection with Cas12a

CRISPR/Cas12a has emerged as a powerful tool for nucleic acid detection; however, its clinical utility is severely hampered by intrinsic limitations in single-nucleotide variant (SNV) discrimination, reliance on pre-processed single-stranded DNA (ssDNA) templates, and cumbersome multi-step workflows. Here, we report a novel molecular design prin...

#10 [13.7] Kinetic-Gated Signal Transduction Decouples Binding Affinity in a Dual-Pocket Riboswitch RNA

Abstract RNA has emerged beyond its traditional biological role to become a premier biorecognition element in biosensor design. While single-target RNA sensors demonstrate high specificity, multi-pocket variants, such as the tetrahydrofolate (THF) riboswitch, enable complex signal integration and cooperative allosteric regulation. Intriguingly, ...
