To preserve their integrity over long timescales, the information‐carrying DONs are often stored in a frozen state. Here, we investigate the effect of repeated freeze–thaw (F/T) cycles on the structural and functional integrity of DONs carrying biotin (Bt) modifications. Streptavidin (SAv) binding is used to visualize the stored information by atomic force microscopy (AFM) before and after 40 F/T cycles. Two strategies are compared by F/T cycling of (I) SAv‐bound DONs and (II) SAv‐free DONs that are exposed to SAv directly before AFM imaging. Our results reveal that while the DONs retain their overall shape, F/T cycling induces a small amount of damage, leading to slightly reduced SAv binding. Adding glycerol at mM concentrations efficiently protects the DONs and restores the original SAv binding yields. Nevertheless, SAv exposure after F/T cycling leads to slightly higher and more consistent SAv binding yields and a lower background of nonspecifically adsorbed SAv compared to Strategy I. This makes information readout by AFM more efficient and renders Strategy II more convenient for long‐term storage of information‐carrying DONs with repeated information readout.</jats:p>","lang":"eng"}],"user_id":"48864","department":[{"_id":"302"}],"_id":"65082","language":[{"iso":"eng"}],"article_number":"e202500161"},{"status":"public","abstract":[{"text":"<jats:title>Abstract</jats:title>\r\n                  <jats:p>Lithographic surface patterning is a cornerstone of modern materials and device fabrication. Although the available lithography techniques are constantly being advanced to push the feature sizes down to the few-nanometer scale, such developments are associated with many technological and economic challenges. Combining established top-down lithography with bottom-up self-assembly strategies has the potential to overcome those challenges and enable the manipulation of matter with molecular precision. One of the most exciting approaches in this regard is to harness the programmability of DNA self-assembly to create precise DNA nanostructure masks to be used in the lithographic patterning of diverse substrates. DNA nanotechnology has provided us with a versatile toolbox for the high-yield synthesis of 2D and 3D nanostructures with complex, user-defined shapes at unprecedented molecular accuracy. Consequently, the last decade has seen intense research efforts aimed at transferring such DNA nanostructure shapes into functional organic and inorganic materials and we have now arrived at a point where sophisticated molecular lithography approaches utilize DNA nanostructure masks for the fabrication of plasmonic surfaces for metamaterials and sensing applications. This review summarizes how the spatial information of such DNA nanostructure masks can be transferred into various organic and inorganic materials through selective etching and deposition steps. The review also discusses recent developments toward all-purpose molecular lithography schemes and highlights promising extensions of the discussed methods toward new materials systems and application fields.</jats:p>","lang":"eng"}],"type":"journal_article","publication":"Journal of Physics D: Applied Physics","language":[{"iso":"eng"}],"user_id":"48864","department":[{"_id":"302"}],"_id":"65108","citation":{"apa":"Keller, A.

DNA origami in particular provides unique self‐assembly properties, not only enabling a vast variety of functionalization schemes but also presenting a promising route to fabricate large‐scale, bottom‐up nanostructured arrays. This approach has comparable precision to electron beam lithography but avoids slow and expensive patterning steps. However, self‐assembly of lattices with high order and well‐defined periodicity requires careful tuning of the deposition parameters and interactions involved, which has been done mostly on mica so far. As mica is not compatible with standard microfabrication processes, we investigate here the assembly of DNA origami lattices on the most general microfabrication material, that is, silicon wafers, which has turned out to be rather challenging. We study how the forming of polycrystalline 2D‐fishnet‐type lattices is influenced by different incubation conditions and strengths of the origami–origami and origami‐surface interactions, with the aim to create large‐scale single‐crystalline lattices. The lattices are characterized by atomic force microscopy and analyzed for precision of formation, achievable domain size, and surface coverage of well‐formed lattices. Thanks to the silicon substrate, these DNA origami lattices can be further combined with traditional microfabrication processes to turn them, for example, into metamaterials with novel optical properties.</jats:p>"}],"status":"public","_id":"65490","department":[{"_id":"302"}],"user_id":"48864","article_number":"e202500813","language":[{"iso":"eng"}]},{"publication_status":"published","publication_identifier":{"isbn":["9781071643938","9781071643945"],"issn":["1064-3745","1940-6029"]},"citation":{"chicago":"Parikka, Johannes, Bhanu Kiran Pothineni, Heini Järvinen, Kosti Tapio, Adrian Keller, and J.

Lattice quality and assembly kinetics are controlled by various environmental parameters, including the employed surface, the assembly temperature, and the ionic composition of the buffer, with optimized parameter combinations resulting in highly ordered lattices that can span surface areas of several cm<jats:sup>2</jats:sup>. Established assembly protocols, however, employ assembly times ranging from hours to days. Here, the assembly of highly ordered hexagonal DNA origami lattices at mica surfaces is observed within few minutes using high-speed atomic force microscopy (HS-AFM). A moderate increase in the DNA origami concentration enables this rapid assembly. While forming a regular lattice takes 10 min at a DNA origami concentration of 4 nM, this time is shortened to about 2 min at a concentration of 6 nM. Increasing the DNA origami concentration any further does not result in shorter assembly times, presumably because DNA origami arrival at the mica surface is diffusion-limited. Over short length scales up to 1 µm, lattice order is independent of the DNA origami concentration. However, at larger length scales of a few microns, a DNA origami concentration of 10 nM yields slightly better order than lower and higher concentrations. Therefore, 10 nM can be considered the optimum concentration for the rapid assembly of highly ordered DNA origami lattices. These results thus represent an important step toward the industrial-scale application of DNA origami-based lithography masks.</jats:p>","lang":"eng"}],"type":"journal_article","publication":"Discover Nano"},{"user_id":"48864","department":[{"_id":"302"}],"_id":"59992","language":[{"iso":"eng"}],"type":"journal_article","publication":"RSC Applied Interfaces","status":"public","abstract":[{"text":"<jats:p>The immobilization of DNA origami nanostructures on solid surfaces is an important prerequisite for their application in many biosensors.

However, silicon oxide surfaces come in many different forms and the type and history of the silicon oxide has a large effect on its physicochemical surface properties. Therefore, we here investigate DNA origami lattice formation on differently fabricated SiOx films on silicon wafers after wet-chemical oxidation by RCA1. Despite having similar oxide compositions and hydroxylation states, of all surfaces tested, only thermally grown SiOx performs similarly well as native oxide. For the other SiOx films deposited by plasma-enhanced chemical vapor deposition and magnetron sputtering, DNA origami adsorption is strongly suppressed. This is attributed to an increased surface roughness and a lower oxide density, respectively. Our results demonstrate that the employed SiOx surface may decide over the outcome of an experiment and should be considered as an additional parameter that may require optimization and fine-tuning before high-quality lattices can be assembled.

One of these challenges lies in the high strain-specificity of most bacteriophages, which makes it necessary to screen large phage collections against the target pathogens in order to identify suitable candidates for the formulations of personalized therapeutic phage cocktails. In this work, we evaluate the potential of quartz crystal microbalance with dissipation monitoring (QCM-D) to identify and detect phage infection and subsequent lysis of bacteria immobilized on the surfaces of the QCM-D sensors. Using lytic <jats:italic>Escherichia coli</jats:italic> phage T7 as a model, we show that phage infection of <jats:italic>E. coli</jats:italic> cells results in various unique alterations in the behaviors of the frequency (Δ<jats:italic>f</jats:italic>) and dissipation (Δ<jats:italic>D</jats:italic>) signals, which are not observed during exposure of the <jats:italic>E. coli</jats:italic> strain to non-infectious <jats:italic>Bacillus subtilis</jats:italic> phage phi29 at similar concentration. To aid future phage screening campaigns, we furthermore identify a single measurement parameter, i.e., the spread between the different overtones of Δ<jats:italic>D</jats:italic>, that can be used to detect phage-induced lysis. For T7 infection of <jats:italic>E. coli</jats:italic>, this is achieved within 4 h after inoculation, including immobilization and growth of the bacteria on the sensor surface, as well as the completed phage propagation cycle. Given the commercial availability of highly automated multichannel systems and the fact that this approach does not require any sensor modifications, QCM-D has the potential to become a valuable tool for screening medium-sized phage collections against target pathogens.</jats:p>\r\n          <jats:p>\r\n            <jats:bold>Graphical Abstract</jats:bold>\r\n          </jats:p>"}],"status":"public"},{"status":"public","abstract":[{"lang":"eng","text":"<jats:p>DNA origami nanostructures are powerful molecular tools for the controlled arrangement of functional molecules and thus have important applications in biomedicine, sensing, and materials science.

So far, targeting bacteria with DONs has been achieved exclusively via aptamers, which suffer from drawbacks such as sensitivity toward environmental conditions and reduced binding after immobilization or conjugation. Here, an alternative approach is presented based on the modification of DONs with the cell wall‐binding glycopeptide antibiotic vancomycin. Using strain‐promoted azide‐alkyne cycloaddition, azide‐modified vancomycin is conjugated to selected staple strands and subsequently incorporated into 2D DON triangles. The resulting constructs show specific binding to the Gram‐positive species <jats:italic>Bacillus subtilis</jats:italic> (<jats:italic>B. subtilis</jats:italic>) and <jats:italic>Staphylococcus capitis</jats:italic> (<jats:italic>S. capitis</jats:italic>), and remarkably, to Gram‐negative <jats:italic>Escherichia coli</jats:italic> (<jats:italic>E. coli</jats:italic>), but no antimicrobial activity at vancomycin concentrations up to at least 2.91 μM.

The progressive etching of the PLA film in direct contact with the nitrogen plasma was monitored in situ using polarization modulated infrared reflection absorption spectroscopy (PM‐IRRAS). No appreciative changes in composition were seen with PM‐IRRAS, indicating that the etching did not significantly affect the bulk composition. Atomic force microscopy characterization of the plasma‐etched films showed that the PLA films are homogeneously etched. Subsequent ex situ XPS analysis of the treated surface revealed the presence of C‐N bonds in the surface‐near region that could be associated with amino and/or amide surface species. PLA films were also alternatively exposed to nitrogen ion beams produced by an electron‐cyclotron‐resonance (ECR) plasma source and were investigated in vacuo by XPS. This treatment revealed the partial substitution of surface oxygen species by nitrogen, resulting in a similar surface modification as in the plasma case. The comparison of XPS data and water contact angle studies suggest that the activated surfaces show a reorientation of macromolecular fragments in the surface‐near region depending on the polarity of the phase with which they are in contact. Under ultra‐high vacuum (UHV) conditions, the surface tends to lower its surface energy, while in contact with the aqueous phase, subsurface polar groups orientate outwards, which enables the formation of hydrogen bonds.</jats:p>"}],"type":"journal_article","publication":"Surface and Interface Analysis","doi":"10.1002/sia.7406","title":"In Situ PM‐IRRAS and XPS Analysis of Nitrogen Plasma Surface Modification of Polylactide Thin Films","date_created":"2025-12-04T13:12:03Z","author":[{"first_name":"Sandra","full_name":"Gołębiowska, Sandra","last_name":"Gołębiowska"},{"first_name":"Markus","last_name":"Voigt","full_name":"Voigt, Markus"},{"last_name":"de los Arcos de Pedro","orcid":"0000-0002-8684-273X ","id":"54556","full_name":"de los Arcos de Pedro, Maria Teresa","first_name":"Maria Teresa"},{"first_name":"Guido","last_name":"Grundmeier","id":"194","full_name":"Grundmeier, Guido"}],"volume":57,"publisher":"Wiley","date_updated":"2025-12-04T13:13:00Z","citation":{"ama":"Gołębiowska S, Voigt M, de los Arcos de Pedro MT, Grundmeier G.
