Merging of bridging staples with adjacent oligonucleotide sequences leads to a moderate increase of DNA origami stability, while enzymatic ligation after assembly yields a reinforced nanostructure with superior stability at up to 37 °C and in the presence of 6 M urea.

Due to the tremendous success of the DNA origami technique in the academic field, considerable efforts currently aim at the translation of this technology from a laboratory setting to real-world applications, such as nanoelectronics, drug delivery, and biosensing. While many of these real-world applications rely on an intact DNA origami shape, they often also subject the DNA origami nanostructures to rather harsh and potentially damaging environmental and processing conditions. Furthermore, in the context of DNA origami mass production, the long-term storage of DNA origami nanostructures or their pre-assembled components also becomes an issue of high relevance, especially regarding the possible negative effects on DNA origami structural integrity. Thus, we investigated the effect of staple age on the self-assembly and stability of DNA origami nanostructures using atomic force microscopy. Different harsh processing conditions were simulated by applying different sample preparation protocols. Our results show that staple solutions may be stored at −20 °C for several years without impeding DNA origami self-assembly. Depending on DNA origami shape and superstructure, however, staple age may have negative effects on DNA origami stability under harsh treatment conditions. Mass spectrometry analysis of the aged staple mixtures revealed no signs of staple fragmentation. We, therefore, attribute the increased DNA origami sensitivity toward environmental conditions to an accumulation of damaged nucleobases, which undergo weaker base-pairing interactions and thus lead to reduced duplex stability.}}, author = {{Kielar, Charlotte and Xin, Yang and Xu, Xiaodan and Zhu, Siqi and Gorin, Nelli and Grundmeier, Guido and Möser, Christin and Smith, David M. and Keller, Adrian}}, issn = {{1420-3049}}, journal = {{Molecules}}, pages = {{2577}}, title = {{{Effect of Staple Age on DNA Origami Nanostructure Assembly and Stability}}}, doi = {{10.3390/molecules24142577}}, volume = {{24}}, year = {{2019}}, } @article{22655, author = {{Ramakrishnan, S and Shen, B and Kostiainen, MA and Grundmeier, Guido and Keller, Adrian and Linko, V}}, issn = {{1439-4227}}, journal = {{ChemBioChem}}, number = {{22}}, pages = {{2818--2823}}, title = {{{Real-Time Observation of Superstructure-Dependent DNA Origami Digestion by DNase I Using High-Speed Atomic Force Microscopy.}}}, doi = {{10.1002/cbic.201900369}}, volume = {{20}}, year = {{2019}}, } @article{22656, author = {{Julin, S and Korpi, A and Shen, B and Liljeström, V and Ikkala, O and Keller, Adrian and Linko, V and Kostiainen, MA}}, issn = {{2040-3364}}, journal = {{Nanoscale}}, number = {{10}}, pages = {{4546--4551}}, title = {{{DNA origami directed 3D nanoparticle superlattice via electrostatic assembly.}}}, doi = {{10.1039/c8nr09844a}}, volume = {{11}}, year = {{2019}}, } @article{22657, author = {{Hajiraissi, Roozbeh and Hanke, Marcel and Gonzalez Orive, Alejandro and Duderija, Belma and Hofmann, Ulrike and Zhang, Yixin and Grundmeier, Guido and Keller, Adrian}}, issn = {{2470-1343}}, journal = {{ACS Omega}}, pages = {{2649--2660}}, title = {{{Effect of Terminal Modifications on the Adsorption and Assembly of hIAPP(20–29)}}}, doi = {{10.1021/acsomega.8b03028}}, volume = {{4}}, year = {{2019}}, } @article{22687, author = {{Meinderink, Dennis and Nolkemper, Karlo J.R. and Bürger, Julius and Orive, Alejandro G. and Lindner, Jörg K.N. and Grundmeier, Guido}}, issn = {{0257-8972}}, journal = {{Surface and Coatings Technology}}, pages = {{112--122}}, title = {{{Spray coating of poly(acrylic acid)/ZnO tetrapod adhesion promoting nanocomposite films for polymer laminates}}}, doi = {{10.1016/j.surfcoat.2019.06.083}}, year = {{2019}}, } @article{22545, author = {{Mai, Lukas and Zanders, David and Subaşı, Ersoy and Ciftyurek, Engin and Hoppe, Christian and Rogalla, Detlef and Gilbert, Wolfram and de los Arcos de Pedro, Maria Teresa and Schierbaum, Klaus and Grundmeier, Guido and Bock, Claudia and Devi, Anjana}}, issn = {{1944-8244}}, journal = {{ACS Applied Materials & Interfaces}}, pages = {{3169--3180}}, title = {{{Low-Temperature Plasma-Enhanced Atomic Layer Deposition of Tin(IV) Oxide from a Functionalized Alkyl Precursor: Fabrication and Evaluation of SnO2-Based Thin-Film Transistor Devices}}}, doi = {{10.1021/acsami.8b16443}}, year = {{2019}}, } @article{22544, author = {{Mai, Lukas and Boysen, Nils and Zanders, David and de los Arcos de Pedro, Maria Teresa and Mitschker, Felix and Mallick, Bert and Grundmeier, Guido and Awakowicz, Peter and Devi, Anjana}}, issn = {{0947-6539}}, journal = {{Chemistry – A European Journal}}, pages = {{7489--7500}}, title = {{{Potential Precursor Alternatives to the Pyrophoric Trimethylaluminium for the Atomic Layer Deposition of Aluminium Oxide}}}, doi = {{10.1002/chem.201900475}}, year = {{2019}}, } @article{22543, abstract = {{

X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared (FTIR) reflection absorption spectroscopy confirmed the monolayer formation. Water adsorption isotherms were studied by a combination of in-situ FTIR reflection spectroscopy and quartz crystal microbalance (QCM) while macroscopic wetting was analysed by contact angle measurements. The comparative data evaluation indicates that the macroscopic wetting behaviour was changed as expected, however, that water nanodroplets formed both at intrinsic defects of the FOTS monolayer and at the FOTS/SiOx interface. Capillary bridges of liquid water are dominantly formed in the confined particle contact areas and between surface asperities on the particles.

However, the evolution of their interface structure with the cation’s alkyl chain length n from Coulomb to van der Waals interaction domination has not yet been studied for even a single broad homologous RTIL series. We present here such a study of the liquid–air interface for n=2to 22, using angstrom-resolution X-ray methods. For n<6, a typical “simple liquid” monotonic surface-normal electron density profile ρe(z) is obtained, like those of water and organic solvents. For n>6, increasingly more pronounced nanoscale self-segregation of the molecules’ charged moieties and apolar chains yields surface layering with alternating regions of headgroups and chains. The layering decays into the bulk over a few, to a few tens, of nanometers. The layering periods and decay lengths, their linear n dependence, and slopes are discussed within two models, one with partial-chain interdigitation and the other with liquid-like chains. No surface-parallel long-range order is found within the surface layer. For n=22, a different surface phase is observed above melting. Our results also impact general liquid-phase issues like supramolecular self-aggregation and bulk–surface structure relations.}}, author = {{Haddad, Julia and Pontoni, Diego and Murphy, Bridget M. and Festersen, Sven and Runge, Benjamin and Magnussen, Olaf M. and Steinrück, Hans-Georg and Reichert, Harald and Ocko, Benjamin M. and Deutsch, Moshe}}, issn = {{0027-8424}}, journal = {{Proceedings of the National Academy of Sciences}}, pages = {{E1100--E1107}}, title = {{{Surface structure evolution in a homologous series of ionic liquids}}}, doi = {{10.1073/pnas.1716418115}}, volume = {{115}}, year = {{2018}}, } @article{22658, author = {{Kielar, Charlotte and Ramakrishnan, Saminathan and Fricke, Sebastian and Grundmeier, Guido and Keller, Adrian}}, issn = {{1944-8244}}, journal = {{ACS Applied Materials & Interfaces}}, pages = {{44844--44853}}, title = {{{Dynamics of DNA Origami Lattice Formation at Solid–Liquid Interfaces}}}, doi = {{10.1021/acsami.8b16047}}, volume = {{10}}, year = {{2018}}, }
