#1 [19.5] pH-dependent allosteric remodeling of a bacterial riboswitch couples alkaline activation to metal sensing.

The widespread yybP-ykoY riboswitches control bacterial manganese (Mn) homeostasis by activating exporter expression in response to intracellular Mn2+ levels. The Escherichia coli alx riboswitch distinctively couples Mn2+ sensing to cytoplasmic alkalinity, but the mechanism is unknown. We show that pH tunes the alx aptamer's conformational sampl...

#2 [16.2] 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...

#3 [14.7] ShapeME: A Tool and Web Front-end for De Novo Discovery of Structural Motifs Underpinning Protein-DNA Interactions.

Determining where proteins bind a genome is paramount to understanding gene regulation. In addition to DNA sequence motifs, structural motifs (e.g., a narrow minor groove width) determine binding for some proteins (Rohs et al., 2009) [1]. Algorithms using structural features of DNA to predict protein binding exist (Mathelier et al., 2016; Samee ...

#4 [14.4] Live imaging and interactome analysis of Zika and chikungunya viral RNAs via dual-action aptamer tag

Arthropod-borne, positive-sense RNA viruses encompass many human pathogens posing significant health threats worldwide. Understanding intracellular dynamics and host-factor interactions of the viral genome is essential for devising effective antiviral strategies. Here, we engineer dual-labeled Zika and chikungunya viruses incorporating a Mango-I...

#5 [14.2] Shared-Output Aptamer-Gated DNA Nanodevices Program NbaSPARDA Trans-Cleavage for Metabolite and Drug Sensing.

Routing chemically distinct small-molecule aptamers into a common nuclease trans-cleavage pathway is constrained by the target-specific output handles of conventional structure-switching aptamers (SSAs). Shared-output aptamer-gated DNA nanodevices are designed so that recognition cores control release of the same short trigger DNA (tDNA). The re...

#6 [13.9] Myelin-Inspired 3D PEGylation of Framework Nucleic Acids Enables Simultaneous Long Circulation and Rapid Renal Clearance.

The rational design of nanomedicines is fundamentally constrained by a physicochemical paradox at the bio-nano interface: strategies to prolong circulation inevitably suppress clearance, often resulting in long-term accumulation and systemic toxicity. To address this, we propose spatial conformation engineering as an additional design dimension ...

#7 [13.9] Modular Lysosome-Targeting Platform Based on a Multivalent DNA Framework for Programmable Protein Degradation.

Targeted degradation of extracellular and membrane-bound proteins holds immense therapeutic potential but remains technically challenging. Lysosome-targeting chimeras (LYTACs) have emerged to bridge this gap, yet platforms built on monomeric aptamers suffer from inadequate stability, inefficient cellular uptake, and a lack of modularity. Here, w...

#8 [13.6] An engineered nanopore identifies saccharides, amino acids, peptides and ribonucleotides

#9 [13.5] A Sprayable Multifunctional Film Based on EGFR-Targeting DNA Nanoactivators for Burn Wound Healing.

Burn treatment remains a tough clinical hurdle, as traditional epidermal growth factor (EGF) treatments suffer from rapid proteolytic degradation and poor skin permeation. Herein, a sprayable, multifunctional film (STAR) based on EGFR-targeting DNA nanoactivators is reported for efficient burn wound healing. The STAR platform combines tannic aci...

#10 [13.5] Antibody- and enzyme-free point-of-care detection of procalcitonin via synergistic nanomachines-activated catalytic assembly (SNCA) assay for early sepsis monitoring.

Procalcitonin (PCT) is an important biomarker for the early assessment and dynamic monitoring of sepsis. However, its routine measurement largely relies on centralized laboratory testing and protein-based recognition or signal-amplification components. Here, we developed an antibody- and enzyme-free synergistic nanomachines-activated catalytic a...
