Title: Hybridization and self‐assembly behaviors of surface‐immobilized DNA in close proximity: A single‐molecule perspective: Nanoscience: Special Issue Dedicated to Professor Paul S. Weiss
Abstract Solid surfaces that are immobilized with DNA molecules underlie an array of biotechnological devices. These surfaces may also mediate the self‐assembly of hierarchical DNA nanostructures. However, a number of fundamental questions concerning the structure–function relationship of these biointerfaces remain, including how these DNA probe molecules organize on the surface and how the spatial organization influences molecular recognition kinetics and interfacial affinity of these DNA molecules at the regime where crowding interactions are important (1–10 nm). This mini‐review covers recent advances in understanding this structure–function relationship by spatially resolving surface hybridization events at the single‐molecule level. Counterintuitive cooperative effects in surface hybridization are discussed and as is how modeling these cooperative effects can be used to predict the hybridization kinetics of a prototypical DNA sensor. Future opportunities in using mechanistic understanding to improve the performance and reliability of DNA sensors and form hierarchical supramolecular structures are also discussed.  more » « less

    Hydrostatic pressure can perturb biomolecular function by altering equilibrium structures and folding dynamics. Its influences are particularly important to deep sea organisms, as maximum pressures reach ≈1100 bar at the bottom of the ocean as a result of the rapid increase in hydraulic pressure (1 bar every 10 meters) under water. In this work, DNA hybridization kinetics has been studied at the single molecule level with external, tunable pressure control ( P max ≈ 1500 bar), realized by incorporating a mechanical hydraulic capillary sample cell into a confocal fluorescence microscope. We find that the DNA hairpin construct promotes unfolding (“denatures”) with increasing pressure by simultaneously decelerating and accelerating the unimolecular rate constants for folding and unfolding, respectively. The single molecule kinetics is then investigated via pressure dependent van’t Hoff analysis to infer changes in the thermodynamic molar volume, which unambiguously reveals that the effective DNA plus solvent volume increases (Δ V 0 > 0) along the folding coordinate. Cation effects on the pressure dependent kinetics are also explored as a function of monovalent [Na + ]. In addition to stabilizing the overall DNA secondary structure, sodium ions at low concentrations are also found to weaken any pressure dependence for the folding kinetics, but with these effects quickly saturating at physiologically relevant levels of [Na + ]. In particular, the magnitudes of the activation volumes for the DNA dehybridization (Δ V ‡unfold) are significantly reduced with increasing [Na + ], suggesting that sodium cations help DNA adopt a more fold-like transition state configuration.

  2. The spatial arrangement of target and probe molecules on the biosensor is a key aspect of the biointerface structure that ultimately determines the properties of interfacial molecular recognition and the performance of the biosensor. However, the spatial patterns of single molecules on practical biosensors have been unknown, making it difficult to rationally engineer biosensors. Here, we have used high-resolution atomic force microscopy to map closely spaced individual probes as well as discrete hybridization events on a functioning electrochemical DNA sensor surface. We also applied spatial statistical methods to characterize the spatial patterns at the single molecule level. We observed the emergence of heterogeneous spatiotemporal patterns of surface hybridization of hairpin probes. The clustering of target capture suggests that hybridization may be enhanced by proximity of probes and targets that are about 10 nm away. The unexpected enhancement was rationalized by the complex interplay between the nanoscale spatial organization of probe molecules, the conformational changes of the probe molecules, and target binding. Such molecular level knowledge may allow one to tailor the spatial patterns of the biosensor surfaces to improve the sensitivity and reproducibility.

  3. AbstractMaterials science is about understanding the relationship between a material’s structure and its properties—in the sphere of mechanical behavior, this includes elastic modulus, yield strength, and other bulk properties. We show in this issue that, analogously, a material’s surface structure governs its surface properties—such as adhesion, friction, and surface stiffness. For bulk materials, microstructure is a critical component of structure; for surfaces, the structure is governed largely by surface topography. The articles in this issue cover the latest understanding of these structure–property connections for surfaces. This includes both the theoretical basis for how properties depend on topography, as well as the latest understanding of how surface topography emerges, how to measure and understand topography-dependent properties, and how to engineer surfaces to improve performance. The present article frames the importance of surface topography and its effect on properties; it also outlines some of the critical knowledge gaps that impede progress toward optimally performing surfaces.

    Peptide nucleic acid (PNA) is a unique synthetic nucleic acid analog that has been adopted for use in many biological applications. These applications rely upon the robust Franklin–Watson–Crick base pairing provided by PNA, particularly at lower ionic strengths. However, our understanding of the relationship between the kinetics of PNA:DNA hybridization and ionic strength is incomplete. Here we measured the kinetics of association and dissociation of PNA with DNA across a range of ionic strengths and temperatures at single-molecule resolution using total internal reflection fluorescence imaging. Unlike DNA:DNA duplexes, PNA:DNA duplexes are more stable at lower ionic strength, and we demonstrate that this is due to a higher association rate. While the dissociation rate of PNA:DNA duplexes is largely insensitive to ionic strength, it is significantly lower than that of DNA:DNA duplexes having the same number and sequence of base pairing interactions. The temperature dependence of PNA:DNA kinetic rate constants indicate a significant enthalpy barrier to duplex dissociation, and to a lesser extent, duplex formation. This investigation into the kinetics of PNA:DNA hybridization provides a framework towards better understanding and design of PNA sequences for future applications.

  5. Abstract Many experimental and computational efforts have sought to understand DNA origami folding, but the time and length scales of this process pose significant challenges. Here, we present a mesoscopic model that uses a switchable force field to capture the behavior of single- and double-stranded DNA motifs and transitions between them, allowing us to simulate the folding of DNA origami up to several kilobases in size. Brownian dynamics simulations of small structures reveal a hierarchical folding process involving zipping into a partially folded precursor followed by crystallization into the final structure. We elucidate the effects of various design choices on folding order and kinetics. Larger structures are found to exhibit heterogeneous staple incorporation kinetics and frequent trapping in metastable states, as opposed to more accessible structures which exhibit first-order kinetics and virtually defect-free folding. This model opens an avenue to better understand and design DNA nanostructures for improved yield and folding performance.
