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. This should be considered in the development of antimicrobial DNA origami nanostructures."}],"status":"public","type":"journal_article","publication":"ChemBioChem","title":"Effect of DNA Origami Nanostructures on Bacterial Growth","doi":"10.1002/cbic.202400091","date_updated":"2024-02-03T12:42:48Z","publisher":"Wiley","author":[{"last_name":"Garcia-Diosa","full_name":"Garcia-Diosa, Jaime Andres","first_name":"Jaime Andres"},{"last_name":"Grundmeier","id":"194","full_name":"Grundmeier, Guido","first_name":"Guido"},{"id":"48864","full_name":"Keller, Adrian","orcid":"0000-0001-7139-3110","last_name":"Keller","first_name":"Adrian"}],"date_created":"2024-02-03T12:41:16Z","year":"2024","citation":{"chicago":"Garcia-Diosa, Jaime Andres, Guido Grundmeier, and Adrian Keller. “Effect of DNA Origami Nanostructures on Bacterial Growth.” ChemBioChem, 2024. https://doi.org/10.1002/cbic.202400091.","ieee":"J.

HF significantly influences the performance of Li-ion batteries, for example by impacting the formation of the solid electrolyte interphase at the anode and by affecting transition metal dissolution at the cathode. Additionally, HF complicates studying fundamental interfacial electrochemistry of Li-ion battery electrolytes, such as direct anion reduction, because it is electrocatalytically relatively unstable, resulting in LiF passivation layers. Methods to selectively remove ppm levels of HF from LiPF6-containing carbonate-based electrolytes are limited. We introduce and benchmark a simple yet efficient electrochemical in situ method to selectively remove ppm amounts of HF from LiPF6-containing carbonate-based electrolytes. The basic idea is the application of a suitable potential to a high surface-area metallic electrode upon which only HF reacts (electrocatalytically) while all other electrolyte components are unaffected under the respective conditions.","lang":"eng"}],"publication":"Journal of The Electrochemical Society"},{"article_type":"original","_id":"53163","department":[{"_id":"163"}],"user_id":"94","status":"public","type":"journal_article","doi":"10.1039/d3py01354e","date_updated":"2024-04-03T11:03:03Z","volume":15,"author":[{"first_name":"Maksim","full_name":"Rodin, Maksim","last_name":"Rodin"},{"last_name":"Helle","full_name":"Helle, David","first_name":"David"},{"first_name":"Dirk","last_name":"Kuckling","id":"287","full_name":"Kuckling, Dirk"}],"intvolume":" 15","page":"661-679","citation":{"chicago":"Rodin, Maksim, David Helle, and Dirk Kuckling. “Pillar[5]Arene-Based Dually Crosslinked Supramolecular Gel as a Sensor for the Detection of Adiponitrile.” Polymer Chemistry 15, no. 7 (2024): 661–79. https://doi.org/10.1039/d3py01354e.","ieee":"M.

It can be easily applied to both molecular dynamics (MD) and Monte Carlo (MC) simulations, including periodic boundary conditions. Multidimensional correlation of the density distributions yields a clear picture of the domain formation due to the subtle balance of different interactions. We apply our approach to the example of force field molecular dynamics simulations of imidazolium-based ionic liquids with different side chain lengths at different temperatures, namely 1-ethyl-3-methylimidazolium chloride, 1-hexyl-3-methylimidazolium chloride, and 1-decyl-3-methylimidazolium chloride, which are known to form distinct liquid domains. We put the results into the context of existing microheterogeneity analyses and demonstrate the advantages and sensitivity of our novel method. Furthermore, we show how to estimate the configuration entropy from our analysis, and we investigate voids in the system.

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."}],"status":"public","publication":"Chemistry – A European Journal","type":"journal_article","title":"Highly Efficient Quenching of Singlet Oxygen by DNA Origami Nanostructures","doi":"10.1002/chem.202402057","publisher":"Wiley","date_updated":"2024-06-07T07:54:02Z","author":[{"full_name":"Garcia-Diosa, Jaime Andres","last_name":"Garcia-Diosa","first_name":"Jaime Andres"},{"id":"194","full_name":"Grundmeier, Guido","last_name":"Grundmeier","first_name":"Guido"},{"full_name":"Keller, Adrian","id":"48864","last_name":"Keller","orcid":"0000-0001-7139-3110","first_name":"Adrian"}],"date_created":"2024-06-07T07:53:50Z","year":"2024","citation":{"short":"J.A.

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. Mg2+ ions can efficiently protect the DNA origami nanostructures from ROS‐induced damage and may even heal some of the damage obtained under Mg2+‐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."}],"user_id":"48864","department":[{"_id":"302"}],"_id":"55310","language":[{"iso":"eng"}]},{"language":[{"iso":"eng"}],"department":[{"_id":"2"},{"_id":"389"}],"user_id":"53339","_id":"55371","status":"public","abstract":[{"text":"AbstractThe activation of C(sp3)−F bonds by the commercially available catalyst B(C6F5)3 is reported and applied in reactions with arenes, allylic, vinylic and acetylenic silanes, and olefins to achieve a variety of C−C bond formations (45 examples).","lang":"eng"}],"publication":"Advanced Synthesis & Catalysis","type":"journal_article","doi":"10.1002/adsc.202400511","title":"Tris(pentafluorophenyl)borane‐Catalyzed Functionalization of Benzylic C−F Bonds","volume":366,"author":[{"last_name":"Hoppe","full_name":"Hoppe, Axel","first_name":"Axel"},{"first_name":"Arne J.","last_name":"Stepen","full_name":"Stepen, Arne J."},{"first_name":"Laura","full_name":"Köring, Laura","last_name":"Köring"},{"first_name":"Jan","orcid":"0000-0002-3698-668X","last_name":"Paradies","id":"53339","full_name":"Paradies, Jan"}],"date_created":"2024-07-24T09:16:15Z","date_updated":"2024-07-24T09:18:18Z","publisher":"Wiley","page":"2933-2938","intvolume":" 366","citation":{"apa":"Hoppe, A., Stepen, A.

Combining a polyzwitterionic/antifouling and a polycationic/antibacterial block with a central anchoring block for attachment to titanium oxide surfaces affords surface coatings that exhibit antifouling properties against proteins and allow for surface regeneration by clearing adhering proteins by employing a salt washing step. The surfaces also kill bacteria by contact killing, which is aided by a nonfouling block. The synthesis of block copolymers of 4‐vinyl pyridine (VP), dimethyl 4‐vinylbenzyl phosphonate (DMVBP), and 4‐vinylbenzyltrimethyl ammonium chloride (TMA) is achieved on the multigram scale via RAFT polymerization with good end group retention and narrow dispersities. By polymer analogous reactions, poly(4‐vinyl pyridinium propane sulfonate‐block‐4‐vinylbenzyl phosphonic acid‐block‐4‐vinylbenzyl trimethylammonium chloride) (P(VSP64‐b‐PA14‐b‐TMA64)) is obtained. The antifouling properties against the model protein pepsin and the salt‐induced surface regeneration are shown in surface plasmon resonance (SPR) experiments, while independently the antibacterial and antifouling properties of coated titanium substrates are successfully tested in preliminary microbiological assays against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). This strategy may contribute to the development of long‐term effective antibacterial implant surface coatings to suppress biomedical device‐associated infections."}],"publication":"Macromolecular Bioscience","doi":"10.1002/mabi.202400261","main_file_link":[{"url":"https://onlinelibrary.wiley.com/doi/10.1002/mabi.202400261"}],"volume":25,"author":[{"full_name":"Methling, Rafael","last_name":"Methling","first_name":"Rafael"},{"first_name":"Michael","full_name":"Greiter, Michael","last_name":"Greiter"},{"full_name":"Al‐Zawity, Jiwar","last_name":"Al‐Zawity","first_name":"Jiwar"},{"last_name":"Müller","full_name":"Müller, Mareike","first_name":"Mareike"},{"full_name":"Schönherr, Holger","last_name":"Schönherr","first_name":"Holger"},{"last_name":"Kuckling","full_name":"Kuckling, Dirk","id":"287","first_name":"Dirk"}],"date_updated":"2025-04-11T07:09:03Z","intvolume":" 25","citation":{"ama":"Methling R, Greiter M, Al‐Zawity J, Müller M, Schönherr H, Kuckling D.

A remaining dominant challenge in today's pharmacotherapy is the limited selectivity of active pharmaceutical ingredients and associated undesirable side effects. Controlled drug release can be promoted by smart drug delivery systems, which release embedded API primarily depending on specific stimuli. Consequently, also the microenvironment of tumor tissue can be used advantageously. Dithiothreitol (DTT) based self-immolative polydisulfides were synthesized that preferentially respond to pathologically increased glutathione (GSH) concentrations, as found in solid tumors. The synthesis with different degrees of polymerisation was investigated as well as the synthesis of a copolymer consisting of dithiothreitol and butanedithiol (BDT). Toxicity tests were carried out on pure polymers and their degradation products. The ability to degrade was examined at pathological and physiological glutathione concentrations in order to test the suitability of the polymer as a matrix for nanoparticulate carrier systems. In addition, the processability of one polymer into nanoparticles was investigated as well as the degradation behaviour with glutathione.","lang":"eng"}],"publication":"RSC Advances","title":"Self-immolative polydisulfides and their use as nanoparticles for drug delivery systems","publisher":"Royal Society of Chemistry (RSC)","date_created":"2025-04-11T07:03:03Z","year":"2024","issue":"48","article_type":"original","_id":"59508","user_id":"94","department":[{"_id":"163"}],"status":"public","type":"journal_article","main_file_link":[{"url":"https://pubs.rsc.org/en/content/articlelanding/2024/ra/d4ra07228f"}],"doi":"10.1039/d4ra07228f","date_updated":"2025-04-11T07:06:22Z","author":[{"first_name":"Katharina","last_name":"Völlmecke","full_name":"Völlmecke, Katharina"},{"full_name":"Kramer, Maurice","last_name":"Kramer","first_name":"Maurice"},{"last_name":"Horky","full_name":"Horky, Corinna","first_name":"Corinna"},{"first_name":"Oliver","full_name":"Dückmann, Oliver","last_name":"Dückmann"},{"full_name":"Mulac, Dennis","last_name":"Mulac","first_name":"Dennis"},{"full_name":"Langer, Klaus","last_name":"Langer","first_name":"Klaus"},{"first_name":"Dirk","last_name":"Kuckling","id":"287","full_name":"Kuckling, Dirk"}],"volume":14,"citation":{"ieee":"K.
