Summary: We reported a facile, base-sequence-independent strategy for logically controlling DNA self-assembly through external molecules. The INHIBIT and XOR logic controls over the assembly/disassembly of DNA polyhedra were realized through cystamine (Cyst) and ethylenediamine (EN) respectively. Our work provides a sequence-independent strategy for logically controlling DNA self-assembly, opening up new possibilities for dynamic DNA nanotechnology.

Summary: In this study, the ordered self-assembly of CuNCs using DNA nanoribbon as the template (DNR/CuNCs) was found to improve the electrochemiluminescence (ECL) properties of CuNCs compared with individual CuNCs. The DNR/CuNCs showed a high ECL yield of 46.8% in K2S2O8, which was approximately 68 times higher than that of individual CuNCs. This strategy was also successfully applied to other ECL emitters, such as gold nanoclusters and the Ru(bpy)(3)(2+)/TPrA system. Furthermore, a DNR/CuNC-based ECL biosensor with higher sensitivity was constructed for dopamine determination, showing the potential of DNR/CuNCs as a new type of superior luminophore candidate in ECL bioanalysis.

Summary: This study uses PhAST technology to investigate the structural changes of nucleosomes, revealing similarities and differences between nucleosome assembly and disassembly processes. The results suggest that the efficiency of DNA-histone binding is influenced by the DNA sequence and the amplitude of PhAST signals changes differently during assembly and disassembly. These findings provide new insights into the role of DNA sequence in gene expression regulation and shed light on how the intrinsic properties of DNA are integrated into the control of chromatin structure.

Summary: Membrane-spanning nanopores have diverse applications in label-free single-molecule sensing, nucleic acid sequencing, and research in biology and biophysics. The limitations of naturally occurring and synthetic inorganic nanopores can be overcome by functionalizing existing pores with DNA strands and creating a new class of DNA nanopores. This review focuses on the progress and potential applications of functional DNA nanopores.

Summary: This article explores new design principles for making self-limiting architectures using self-assembly. The authors use DNA origami to create triangular subunits with specific interactions and binding angles, and study their assembly into tubules with a self-limited width. They demonstrate that the tubules can reach significant lengths and that their width can be controlled through geometric programming. They also find that the width and chirality of the tubules can be manipulated by increasing the number of subunit species. These findings provide insights into the role of assembly complexity and geometry in self-limiting assembly and have potential applications in other self-limiting architectures.

Summary: Here we report the design and optimization of an antibody-responsive, DNA-based device that enables communication between non-interacting proteins. The device recognizes and binds a specific antibody, causing a conformational change that releases a DNA strand regulating the activity of a target protein. We demonstrate the antibody-induced control of thrombin and Taq DNA polymerase, showcasing the versatility of this strategy in regulating protein-protein communication in artificial networks.

Summary: This study presents a general approach to achieve dissipative control over toehold-mediated strand-displacement, a widely used reaction in DNA nanotechnology. By re-engineering the classic reaction, the high-energy invader strand is converted into a low-energy waste product, allowing the system to spontaneously return to its original state over time. This method enables unique temporal activation of DNA systems and is reversible and highly controllable.

Summary: This study developed a cell-free in vitro transcription system for the detection of specific target antibodies. The system uses programmable antigen-conjugated DNA-based conformational switches that can trigger cell-free transcription upon binding to a target antibody, resulting in the production of a light-up fluorescence-activating RNA aptamer. The system combines the programmability and responsiveness of DNA-based systems with the specificity and sensitivity offered by in vitro genetic circuitries and commercially available transcription kits. The study demonstrates that cell-free transcriptional switches can efficiently measure antibody levels directly in blood serum and can be adapted to different antibodies.

Summary: In this study, we demonstrate the use of DNA repair enzymes to control the assembly of DNA-based structures. By designing responsive nucleic acid modules and utilizing specific enzyme repair activity, we were able to achieve the self-assembly of DNA tiles into tubular structures. This approach is programmable, specific, and orthogonal, allowing for accurate prediction of tile distribution. Additionally, we show that BER-enzyme inhibitors can be used to control DNA-tile assembly in a specific and concentration-dependent manner.

Summary: In this study, a strategy for programmable delayed onset of toehold-mediated DNA strand displacement reactions (SDRs) is demonstrated. The strategy involves the use of blocker strands to inhibit strand displacement initially, followed by enzymatic degradation of the blocker strand to enable SDR. The kinetics of the blocker enzymatic degradation controls the timing of SDR initiation. The strategy is versatile and can be orthogonally controlled by different enzymes targeting specific blocker strands.
