#1 [20.2] High affinity and selective DNA aptamers for the detection of tobramycin in eye drops.

Tobramycin is a frontline aminoglycoside antibiotic with a narrow therapeutic window. Here, we report the selection of high-affinity DNA aptamers using a library-immobilization based SELEX strategy. The lead aptamer, TOB-2, binds tobramycin with a dissociation constant of 420 nM as determined by isothermal titration calorimetry, while exhibiting...

#2 [17.1] A Targeted Nanozyme for STING Activation Improves BiTEs Therapy Outcomes in Colorectal Cancer.

Colorectal cancer (CRC) remains a leading cause of cancer-related mortality worldwide, with limited efficacy of conventional therapies due to immunosuppressive tumor microenvironments and high recurrence. While bispecific T-cell engagers (BiTEs) show promise by engaging T cells against tumors, their clinical translation is hindered by poor stabi...

#3 [14.9] COF@DNAzyme Empowering Endogenous Copper for One‐Stitch Bioorthogonal Catalysis‐Based Anticancer Therapy

ABSTRACT Bioorthogonal chemistry, particularly the copper‐catalyzed azide‐alkyne cycloaddition (CuAAC) reaction, holds great promise for in situ prodrug activation to minimize systemic toxicity in disease treatments. However, existing approaches mainly rely on exogenous copper catalysts, which pose a risk of disrupting copper homeostasis and suf...

#4 [14.9] COF@DNAzyme Empowering Endogenous Copper for One-Stitch Bioorthogonal Catalysis-Based Anticancer Therapy.

Bioorthogonal chemistry, particularly the copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction, holds great promise for in situ prodrug activation to minimize systemic toxicity in disease treatments. However, existing approaches mainly rely on exogenous copper catalysts, which pose a risk of disrupting copper homeostasis and suffer from ...

#5 [14.8] Non-Invasive Transdermal Delivery of miR-30a-5p via MUC1-Aptamer-Guided Tetrahedral DNA Nanostructures for Gene Silencing in Cutaneous Melanoma.

Cutaneous malignant melanoma is a highly aggressive skin cancer with poor prognosis. Although microRNA (miRNA)-based gene therapy shows promise, its clinical translation is limited by rapid degradation in serum and the barrier function of the stratum corneum. Herein, we engineer a programmable, targeted, and non-invasive nanoplatform, termed MAR...

#6 [14.1] Membrane-anchored DNA nanodevice with allosteric aptamer arms enables parallel probing and on-site drug delivery.

DNA-based molecular computation enables targeting of cells via multiple surface receptors. However, existing platforms are often limited to single-receptor detection per operation or rely on freely diffusing components, a common source of off-target interference. Here we show an intelligent DNA nanodevice (DND) that integrates multivalent recogn...

#7 [13.5] A Droplet-Microarray Platform for Multiplex Profiling of Breast Cancer Exosome Subtypes in Patients' Blood Plasma Samples.

Breast cancer is highly heterogeneous, with distinct subtypes-luminal A, HER2-positive, and triple-negative-each exhibiting unique behaviors and treatment responses. Accurate identification of these subtypes is essential for guiding personalized therapies and improving outcomes. Exosomes, small extracellular vesicles secreted by tumor cells, hav...

#8 [13.3] Tribos: A Modular Hairpin-Enhanced CRISPR/Cas12a Biosensor for Ultrasensitive Detection of HER2 Protein.

Accurate detection of human epidermal growth factor receptor 2 (HER2) is critical for early breast cancer screening and personalized therapy. This study constructed a target-triggered, hairpin-enhanced CRISPR/Cas12a biosensor named "Tribos" for ultrasensitive HER2 detection. The system integrates an aptamer hairpin switch (HAS), HAS-allosterical...

#9 [12.9] High-Speed Atomic Force Microscopy Reveals Aptamer-Mediated Conformational Trapping of METTL3-METTL14 for m(6)A Inhibition.

The conformational dynamics of METTL3-METTL14 (M3/M14) heterodimer, the catalytic core for N6-methyladenosine (m6A) deposition, remain largely unexplored, limiting insight into dynamic regulation of catalysis and opportunities for therapeutic targeting in cancer. Here, we report the first single-molecule visualization of M3/M14 dynamics by high-...

#10 [12.6] Integrating DNA tetrahedron with affinity magnetic levitation for selective capture and sensitive detection of circulating tumor cells.

Circulating tumor cell (CTC) is an evidenced biomarker for early cancer diagnosis and assessment of treatment response. This necessitates increasing attempt to develop new method for detection of CTCs with highly enriching and anti-interference capacity. Herein, we built a simple platform for CTC detection by combining aptamer-mediated specific ...
