Summary: Deployable geometries are finite auxetic structures that can maintain their overall shape while expanding and contracting. A deployable flight ring made from DNA origami has been demonstrated in this study, showing the feasibility of deployable nanostructures. The flight ring consists of six triangles in two layers that can switch between open and closed states, with a trefoil knot topology and negative Poisson's ratios. This work provides a versatile platform for topological studies and opens up new opportunities for bioengineering.

Summary: DNA self-assembly is a promising method for constructing complex nanostructures. However, the current approach requires separate design and professional operation, limiting its development and application. In this study, a novel point-and-shoot strategy based on enzyme-assisted DNA paper-cutting was proposed to construct planar DNA nanostructures using the same DNA origami as a template. By annealing the long scaffold strand and selected staple strands, planar DNA nanostructures were successfully constructed. This strategy overcomes the complexity limitation of planar DNA nanostructures and simplifies the design and operation process. Overall, this strategy shows great potential for manufacturing DNA nanostructures.

Summary: An orthogonal, noncovalent approach is presented for the assembly of higher-order DNA origami nanostructures. By incorporating perfluorinated tags into DNA origami tiles, their hierarchical assembly is controlled via fluorous-directed recognition. This integrated catch-and-latch approach combining fluorous effect with base-pairing specificity enables increased assembly efficiency and requires fewer DNA sequences, providing a cheap and efficient means for producing discrete superstructures in DNA nanotechnology.

Summary: Monitoring and tracking multiple low-abundance messenger RNAs (mRNAs) simultaneously in situ at subcellular level is crucial for the diagnosis and pathologic analysis of cancer. This study presents polyA-mediated dual-color sticky flares for simultaneous imaging of two types of intracellular mRNA biomarkers. The sticky flares greatly improve the uniformity, detection sensitivity, and response kinetics compared to traditional nanoprobes, enabling enhanced efficiency in live-cell imaging of mRNAs. The proposed polyA-mediated dual-color sticky flares are a pivotal tool for multiple targets imaging in living cells with excellent cell entry efficiency and low cytotoxicity.

Summary: Cancer-associated fibroblasts (CAFs) play a role in chemoresistance and immunosuppression, but direct depletion may lead to increased invasiveness and metastasis. Gemini-like targeting nanoparticles (NPs) have been designed to transform CAFs and eliminate cancer cells, enhancing drug susceptibility and immune cell infiltration. In mouse models of various resistant cancers, a single dose of these NPs resulted in improved chemosensitivity, immune activation, tumor regression, and long-term protection against tumor rechallenge.

Summary: A novel and reusable electrochemiluminescence biosensor was developed using tetrahedral DNA (TDN) signal amplification for ultrasensitive detection of miRNA-27a. The flowered nickel-iron layered double hydroxide@AuNPs (NiFe-LDH@AuNPs) composites increase the amount of hairpin DNA fixed on the electrode. When miRNA is present, TDN-Ru(bpy)(3)(2+) acts as an ECL probe, forming a stable sandwich structure with miRNA-27a and hairpin DNA through base complementation pairing, thus achieving miRNA detection. This biosensor has the characteristics of high sensitivity, excellent selectivity, and good reproducibility.
