#1 [30.1] 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 [22.7] Self-assembled Nano-PROTACs: bridging chemical design and biological barriers in targeted protein degradation.

Self-assembled Nano-PROTACs represent an emerging class of programmable supramolecular degraders that integrate targeted protein degradation with nanoscale delivery to overcome the intrinsic limitations of conventional PROTACs. Conventional PROTACs are often constrained by poor solubility, limited membrane permeability, suboptimal pharmacokineti...

#3 [22.7] G-quadruplexes as therapeutic platforms for anticancer drug delivery: from intrinsic cytotoxicity to drug delivery and nanotechnology.

INTRODUCTION: G-quadruplexes have emerged as a versatile class of oligonucleotides that combine molecular recognition, intrinsic anticancer activity and drug carrier functions, offering new opportunities to improve tumor selectivity and overcome limitations of conventional chemotherapy. AREAS COVERED: This review summarizes structural and biolog...

#4 [15.7] Derivation of functional early gestation decidual natural killer cell subtypes from induced pluripotent stem cells.

Abnormal decidual natural killer cell (dNK) function is linked to pregnancy complications occurring in both early and late gestation, including recurrent pregnancy loss, preeclampsia, and preterm birth. Exploration of dNK heterogeneity as it relates to function is an active area of research; however, most of this work has focused on early gestat...

#5 [14.9] Spatially resolved profiling of extracellular vesicles in tissues with Spatial-EV-seq.

Extracellular vesicles (EVs) have emerged as promising biomarkers for monitoring physiological homeostasis and pathological progression. However, current analytic methods face limitations in preserving spatial information about EVs and their intricate connections to parental and recipient cells. Here, we present Spatial-EV-seq, a method for in s...

#6 [14.8] DNA tetrahedron-mediated vascular targeted delivery of astragaloside IV enhances distraction osteogenesis via PI3K/AKT/FOXO pathway.

Bone regeneration during distraction osteogenesis (DO) remains limited by insufficient vascularization, which delays consolidation and compromises clinical outcomes. Here, we developed a vascular-targeted DNA nanoplatform (TDN@Ast-AptCD34) for the delivery of Astragaloside IV (Ast), a natural compound with pro-angiogenic and osteogenic propertie...

#7 [13.8] Aptamer-functionalized tetrahedral framework nucleic acid delivery of siBhlhe22 for repairing osteoporotic bone defects via dual modulation of PI3K-Akt signaling and purine metabolism.

Osteoporosis is characterized by an imbalance between bone formation and resorption, and the dysregulated differentiation of bone marrow mesenchymal stem cells (BMSCs) plays a central role. Our previous study identified Bhlhe22 as a key negative regulator of osteogenic differentiation; here, we further validate its role in osteoporotic BMSCs (OP...

#8 [13.5] Biofilm surface proximity-induced branched hybridization chain reaction strategy based on microchip electrophoresis for distinguishing exosomes from different cancer cells.

The exosome surface contains various cancer markers that can be suitable candidates for early cancer diagnosis and therapeutic efficacy evaluation. However, due to the very small size of exosomes, major challenges remain to detect tumor markers on their surface. To circumvent these challenges, a signal amplification strategy based on microchip e...

#9 [13.3] Quo Vadis, Electrochemical DNA Biosensor? Lessons from Three Decades of SNP Sensing.

Electrochemical DNA biosensors have been studied for over three decades, producing thousands of publications and a sophisticated engineering toolkit. However, a broad clinical adoption remains limited. The COVID-19 pandemic served as a stress test-global demand, unprecedented funding, accelerated regulatory pathways, and a clearly defined genomi...

#10 [13.2] Thermodynamic-Kinetic Tailored Photothermal-Responsive Molecular Switching for Extracellular Vesicle Manipulation.

Extracellular vesicles (EVs) are central mediators of intercellular communication and promising carriers for oncology diagnosis and therapeutic delivery, yet their isolation remains challenged by inadequate specificity, irreversible capture, and vesicle structural damage. Here, we present the Multifunctional Optically Regulated Plasmonic Heating...
