However, the effect of unmodified DNA origami nanostructures on bacteria is yet to be elucidated. With the aim to obtain a better understanding of this phenomenon, the effect of three DNA origami shapes, i.e., DNA origami triangles, six‐helix bundles (6HBs), and 24‐helix bundles (24HBs), on the growth of Gram‐negative Escherichia coli and Gram‐positive Bacillus subtilis is investigated. These results reveal that while triangles and 24HBs can be used as a source of nutrients by E. coli and thereby promote population growth, their effect is much smaller than that of genomic single‐ and double‐stranded DNA. However, no effect on E. coli population growth is observed for the 6HBs. On the other hand, B. subtilis does not show any significant changes in population growth when cultured with the different DNA origami shapes or genomic DNA. The detailed effect of DNA origami nanostructures on bacterial growth thus depends on the competence signals and uptake mechanism of each bacterial species, as well as the DNA origami shape.

Herein, we demonstrate that DONs are highly efficient singlet oxygen quenchers outperforming double‐stranded (ds) DNA by several orders of magnitude. To this end, a ROS mixture rich in singlet oxygen is generated by light irradiation of the photosensitizer methylene blue and its cytotoxic effect on Escherichia coli cells is quantified in the presence and absence of DONs. DONs are found to be vastly superior to dsDNA in protecting the bacteria from ROS‐induced damage and even surpass established ROS scavengers. At a concentration of 15 nM, DONs are about 50 000 times more efficient ROS scavengers than dsDNA at an equivalent concentration. This is attributed to the dominant role of singlet oxygen, which has a long diffusion length and reacts specifically with guanine. The dense packing of the available guanines into the small volume of the DON increases the overall quenching probability compared to a linear dsDNA with the same number of base pairs. DONs thus have great potential to alleviate oxidative stress caused by singlet oxygen in diverse therapeutic settings.</jats:p>","lang":"eng"}],"publication":"Chemistry – A European Journal","type":"journal_article"},{"publication":"Small Structures","type":"journal_article","status":"public","abstract":[{"text":"<jats:p>DNA origami nanostructures are promising carries for drug delivery applications. However, their limited stability under relevant conditions often presents a challenge. Herein, the structural stability of DNA origami nanostructures is investigated in a setting compatible with their application in photodynamic therapy (PDT). To this end, DNA origami triangles and six‐helix bundles (6HBs) are loaded with the clinically tested photosensitizer methylene blue, which upon irradiation with red light generates reactive oxygen species (ROS) that attack the DNA origami nanostructures. ROS‐induced structural damage is observed to depend on the ionic composition of the surrounding medium and becomes more severe at low ionic strength. Mg<jats:sup>2+</jats:sup> ions can efficiently protect the DNA origami nanostructures from ROS‐induced damage and may even heal some of the damage obtained under Mg<jats:sup>2+</jats:sup>‐free conditions when added after irradiation. Finally, the employed DNA origami 6HBs are more resistant toward ROS‐induced structural damage than the triangles, which is attributed to their markedly different mechanical properties. These results thus provide some fundamental insights into the stabilizing role of DNA origami superstructure that may guide the selection or design of DNA origami nanocarriers with optimized stability for their application in PDT.</jats:p>","lang":"eng"}],"department":[{"_id":"302"}],"user_id":"48864","_id":"55310","language":[{"iso":"eng"}],"publication_identifier":{"issn":["2688-4062","2688-4062"]},"publication_status":"published","citation":{"ieee":"L.

Understanding the adhesion of such peptides and proteins at a molecular level thus represents an important step toward controlling and suppressing biofilm formation on technological and medical materials. This study investigates the molecular adhesion of a pilus‐derived peptide that facilitates biofilm formation of Pseudomonas aeruginosa, a multidrug‐resistant opportunistic pathogen frequently encountered in healthcare settings. Single‐molecule force spectroscopy (SMFS) was performed on chemically etched ZnO surfaces to gather insights about peptide adsorption force and its kinetics. Metal‐free click chemistry for the fabrication of peptide‐terminated SMFS cantilevers was performed on amine‐terminated gold cantilevers and verified by X‐ray photoelectron spectroscopy (XPS) and polarization‐modulated infrared reflection absorption spectroscopy (PM‐IRRAS). Atomic force microscopy (AFM) and XPS analyses reveal stable topographies and surface chemistries of the substrates that are not affected by SMFS. Rupture events described by the worm‐like chain model (WLC) up to 600 pN were detected for the non‐polar ZnO(11‐20) surfaces. The dissociation barrier energy at zero force ΔG(0), the transition state distance xb and bound‐unbound dissociation rate at zero force koff(0) for the single crystalline substrate indicate that coordination and hydrogen bonds dominate the peptide/surface interaction.</jats:p>","lang":"eng"}],"author":[{"first_name":"Tim","full_name":"Prüßner, Tim","last_name":"Prüßner"},{"first_name":"Dennis","id":"32378","full_name":"Meinderink, Dennis","last_name":"Meinderink","orcid":"0000-0002-2755-6514"},{"last_name":"Zhu","full_name":"Zhu, Siqi","first_name":"Siqi"},{"first_name":"Alejandro G.","last_name":"Orive","full_name":"Orive, Alejandro G."},{"first_name":"Charlotte","last_name":"Kielar","full_name":"Kielar, Charlotte"},{"last_name":"Huck","full_name":"Huck, Marten","first_name":"Marten"},{"full_name":"Steinrück, Hans-Georg","id":"84268","orcid":"0000-0001-6373-0877","last_name":"Steinrück","first_name":"Hans-Georg"},{"first_name":"Adrian","full_name":"Keller, Adrian","id":"48864","orcid":"0000-0001-7139-3110","last_name":"Keller"},{"first_name":"Guido","id":"194","full_name":"Grundmeier, Guido","last_name":"Grundmeier"}],"date_created":"2023-11-02T09:23:41Z","publisher":"Wiley","date_updated":"2023-11-02T09:26:00Z","doi":"10.1002/chem.202302464","title":"Molecular Adhesion of a Pilus‐derived Peptide Involved in Pseudomonas aeruginosa Biofilm Formation on non‐polar ZnO Surfaces","publication_status":"published","publication_identifier":{"issn":["0947-6539","1521-3765"]},"citation":{"bibtex":"@article{Prüßner_Meinderink_Zhu_Orive_Kielar_Huck_Steinrück_Keller_Grundmeier_2023, title={Molecular Adhesion of a Pilus‐derived Peptide Involved in Pseudomonas aeruginosa Biofilm Formation on non‐polar ZnO Surfaces}, DOI={<a href=\"https://doi.org/10.1002/chem.202302464\">10.1002/chem.202302464</a>}, journal={Chemistry – A European Journal}, publisher={Wiley}, author={Prüßner, Tim and Meinderink, Dennis and Zhu, Siqi and Orive, Alejandro G. and Kielar, Charlotte and Huck, Marten and Steinrück, Hans-Georg and Keller, Adrian and Grundmeier, Guido}, year={2023} }","short":"T.

The adsorption process was studied on an electropolished alloy under cathodic and anodic overpotentials, compared to the open circuit potential (OCP). To analyze the adsorption process, various complementary interface analytical techniques were employed, including PM-IRRAS (polarization-modulation infrared reflection-absorption spectroscopy), AFM (atomic force microscopy), XPS (X-ray photoelectron spectroscopy), and E-QCM (electrochemical quartz crystal microbalance) measurements. The polarization experiments were conducted within a potential range where charging of the electric double layer dominates, and Faradaic currents can be disregarded. The findings highlight the significant influence of the interfacial charge distribution on the adsorption of BSA and LYZ onto the alloy surface. Furthermore, electrochemical analysis of the protein layers formed under applied overpotentials demonstrated improved corrosion protection properties. These studies provide valuable insights into protein adsorption on titanium alloys under physiological conditions, characterized by varying potentials of the passive alloy.</jats:p>"}],"publisher":"MDPI AG","date_created":"2023-07-03T08:06:28Z","title":"Electrode Potential-Dependent Studies of Protein Adsorption on Ti6Al4V Alloy","issue":"13","year":"2023"},{"status":"public","type":"book_chapter","publication":"Reference Module in Chemistry, Molecular Sciences and Chemical Engineering","language":[{"iso":"eng"}],"_id":"45829","user_id":"48864","department":[{"_id":"302"}],"year":"2023","citation":{"ieee":"A.

In this work, multiprotein adsorption from diluted human serum at gold and oxidized iron surfaces is investigated at different serum concentrations and pH values. Adsorption-induced changes in surface topography and the total amount of adsorbed proteins are quantified by atomic force microscopy (AFM) and polarization-modulation infrared reflection absorption spectroscopy (PM-IRRAS), respectively. For both surfaces, stronger protein adsorption is observed at pH 6 compared to pH 7 and pH 8. PM-IRRAS furthermore provides some qualitative insights into the pH-dependent alterations in the composition of the adsorbed multiprotein films. Changes in the amide II/amide I band area ratio and in particular side-chain IR absorption suggest that the increased adsorption at pH 6 is accompanied by a change in protein film composition. Presumably, this is mostly driven by the adsorption of human serum albumin, which at pH 6 adsorbs more readily and thereby replaces other proteins with lower surface affinities in the resulting multiprotein film.</jats:p>"}],"language":[{"iso":"eng"}],"keyword":["Chemistry (miscellaneous)","Analytical Chemistry","Organic Chemistry","Physical and Theoretical Chemistry","Molecular Medicine","Drug Discovery","Pharmaceutical Science"],"issue":"16","year":"2023","date_created":"2023-08-16T10:51:48Z","publisher":"MDPI AG","title":"Multiprotein Adsorption from Human Serum at Gold and Oxidized Iron Surfaces Studied by Atomic Force Microscopy and Polarization-Modulation Infrared Reflection Absorption Spectroscopy"},{"doi":"10.3390/ijms241612808","title":"Adsorption of Ferritin at Nanofaceted Al2O3 Surfaces","volume":24,"date_created":"2023-08-16T10:52:25Z","author":[{"first_name":"Bhanu K.","full_name":"Pothineni, Bhanu K.","last_name":"Pothineni"},{"first_name":"Sabrina","last_name":"Kollmann","full_name":"Kollmann, Sabrina"},{"first_name":"Xinyang","last_name":"Li","full_name":"Li, Xinyang"},{"first_name":"Guido","full_name":"Grundmeier, Guido","id":"194","last_name":"Grundmeier"},{"last_name":"Erb","full_name":"Erb, Denise J.","first_name":"Denise J."},{"first_name":"Adrian","id":"48864","full_name":"Keller, Adrian","orcid":"0000-0001-7139-3110","last_name":"Keller"}],"date_updated":"2023-08-16T10:53:00Z","publisher":"MDPI AG","intvolume":"        24","citation":{"apa":"Pothineni, B.

Herein, ferritin adsorption at flat and nanofaceted, single-crystalline Al2O3 surfaces is investigated using atomic force microscopy and X-ray photoelectron spectroscopy. The nanofaceted surfaces are generated by the thermal annealing of Al2O3 wafers at temperatures above 1000 °C, which leads to the formation of faceted saw-tooth-like surface topographies with periodicities of about 160 nm and amplitudes of about 15 nm. Ferritin adsorption at these nanofaceted surfaces is notably suppressed compared to the flat surface at a concentration of 10 mg/mL, which is attributed to lower adsorption affinities of the newly formed facets. Consequently, adsorption is restricted mostly to the pattern grooves, where the proteins can maximize their contact area with the surface. However, this effect depends on the protein concentration, with an inverse trend being observed at 30 mg/mL. Furthermore, different ferritin adsorption behavior is observed at topographically similar nanofacet patterns fabricated at different annealing temperatures and attributed to different step and kink densities. These results demonstrate that while protein adsorption at solid surfaces can be notably affected by nanofacet patterns, fine-tuning protein adsorption in this way requires the precise control of facet properties.</jats:p>","lang":"eng"}],"publication":"International Journal of Molecular Sciences","type":"journal_article"}]
