This process can be viewed as performing hundreds of parallel reactions programmed on a self‐assembled nanoscale platform. While previous studies have focused on investigating the collective results of the chemical or enzymatic ligation reactions, herein, the global quantitative analysis of individual ligation reactions is achieved using quantitative PCR (qPCR). By mapping enzymatic ligation efficiency on a trapezoidal substructure representing one‐third of a triangular DON, ligation is shown to preferentially occur at the trapezoid edges rather than at inner sites. Excellent agreement between the experimental ligation yields and docking simulations suggests that this is a result of variations in the ligase docking probability. Ligation products involving more than two consecutive sequences can be generated with each enzyme‐catalyzed reaction as an independent event. Interestingly, the sharp contrast between the edges vs. the inner sites has been abolished by changing the reaction conditions and performing the ligation in a DMSO co‐solvent system. This analytic method provides unprecedented insight into the multiple ligation reactions occurring in parallel within complex DONs and will be an invaluable tool in the translation of DONs from the lab to real‐world applications.</jats:p>","lang":"eng"}],"citation":{"mla":"Hacker, Konrad, et al. “Global Quantitative Analysis of Ligation Reactions in Self‐Assembled DNA Nanostructures at the Single‐Nick Level.” <i>Small</i>, e08136, Wiley, 2026, doi:<a href=\"https://doi.org/10.1002/smll.202508136\">10.1002/smll.202508136</a>.","bibtex":"@article{Hacker_Juricke_Münch_Suma_Keller_Zhang_2026, title={Global Quantitative Analysis of Ligation Reactions in Self‐Assembled DNA Nanostructures at the Single‐Nick Level}, DOI={<a href=\"https://doi.org/10.1002/smll.202508136\">10.1002/smll.202508136</a>}, number={e08136}, journal={Small}, publisher={Wiley}, author={Hacker, Konrad and Juricke, Emilia and Münch, Carolin and Suma, Antonio and Keller, Adrian Clemens and Zhang, Yixin}, year={2026} }","ama":"Hacker K, Juricke E, Münch C, Suma A, Keller AC, Zhang Y.

A persistent challenge in current pharmacotherapy is the limited selectivity of active pharmaceutical ingredients, resulting in undesirable side effects. Smart drug delivery systems, which release encapsulated active pharmaceutical ingredients in response to specific stimuli, offer a potential solution by enabling controlled drug release. This approach can be particularly relevant for exploiting biochemical differences between extracellular and intracellular environments. In this study, self-immolative polydisulfide based polymers manufactured from dithiothreitol were processed into nanoparticle formulations to respond preferentially to elevated glutathione levels, which are characteristic of intracellular environments and are often increased in tumor cells. The influence of polymer chain length on the physicochemical properties of the resulting nanoparticles was investigated. Lumogen® Red was incorporated as a model substance to determine the loading capacity of the carrier system. Degradation was characterized using dynamic light scattering and asymmetric flow field-flow fractionation, as well as by imaging techniques such as atomic force microscopy. Selective release of the embedded substance was demonstrated at elevated glutathione concentrations, while no significant release was observed at extracellularly relevant levels (10 µM glutathione), where the behavior was comparable to the buffer control. Increased release was observed under intracellularly relevant conditions (2 – 10 mM glutathione). These findings support a redox-responsive behavior under intracellular-like conditions. The latter was proven for primary fibroblasts and the cancer cell lines BT-474, MCF-7 and SK-BR-3 by quantification of intracellular low molecular weight thiols. The nanoparticle uptake was confirmed in the investigated cell lines by visualization via confocal laser scanning microscopy. Via lysosomal staining it was shown that nanoparticles accumulate in lysosomes. Furthermore, the carrier system itself showed no cytotoxic properties in cell culture studies against the four different cell types. The developed system is a suitable and very promising smart drug delivery system in the context of controlled drug release.","lang":"eng"}],"publication":"Next Nanotechnology","doi":"10.1016/j.nxnano.2026.100510","article_number":"100510","main_file_link":[{"url":"https://www.sciencedirect.com/science/article/pii/S294982952600149X?via%3Dihub"}],"language":[{"iso":"eng"}],"publication_status":"published","date_updated":"2026-05-20T08:41:56Z","article_type":"original","intvolume":"         9","year":"2026","title":"Smart drug delivery systems for potential targeted cancer therapy: Exploiting increased glutathione levels in tumor microenvironments","author":[{"first_name":"Maurice","last_name":"Kramer","full_name":"Kramer, Maurice"},{"full_name":"Horky, Corinna","first_name":"Corinna","last_name":"Horky"},{"first_name":"Katharina","last_name":"Völlmecke","full_name":"Völlmecke, Katharina"},{"full_name":"Mulac-Hahnen, Dennis","first_name":"Dennis","last_name":"Mulac-Hahnen"},{"first_name":"Fabian","last_name":"Herrmann","full_name":"Herrmann, Fabian"},{"id":"287","first_name":"Dirk","last_name":"Kuckling","full_name":"Kuckling, Dirk"},{"last_name":"Langer","first_name":"Klaus","full_name":"Langer, Klaus"}],"publication_identifier":{"issn":["2949-8295"]}},{"_id":"62957","page":"1-17","volume":32,"user_id":"54277","status":"public","citation":{"chicago":"Elsner, Julia, Claudia Tenberge, and Sabine Fechner. “Modellieren und Denken im Diskontinuum.” <i>Zeitschrift für Didaktik der Naturwissenschaften</i> 32, no. 1 (2026): 1–17. <a href=\"https://doi.org/10.1007/s40573-026-00194-1\">https://doi.org/10.1007/s40573-026-00194-1</a>.","short":"J.

Lower growth rates and a reduced N content, favoring graphitic sp2 structures, hinder industrial scalability due to prolonged deposition times and produce softer, less dense films with inferior hardness, elasticity, and wear resistance. Carbon nitride films deposited by magnetron sputtering exhibit growth behavior strongly influenced by plasma–surface interactions. However, nitrogen resputtering and reduced film growth rates are commonly attributed to chemical etching by positive ions. We propose an additional, unreported power-dependent mechanism involving negative ions formed at the carbon target. These ions are accelerated through the plasma sheath, reaching the substrate with high kinetic energy and inducing both chemical and physical resputtering. This effect is localized to the geometrical projection of the target, as shown by spatially resolved analysis: ellipsometry reveals thickness reduction, and x-ray photoelectron spectroscopy and Raman spectroscopy indicate nitrogen depletion within this region. Correlation between stoichiometry and structural signatures confirms the decisive role of negative ions in modifying the film composition and microstructure. At the same time, the composition of the gas mixture exerts only a minor effect.</jats:p>","lang":"eng"}],"publication":"Journal of Applied Physics","issue":"24","department":[{"_id":"302"}],"type":"journal_article","date_created":"2026-06-25T12:15:04Z","intvolume":"       139","publication_status":"published","date_updated":"2026-06-25T12:18:17Z","publication_identifier":{"issn":["0021-8979","1089-7550"]},"author":[{"first_name":"Christian","last_name":"Wieschhoff","full_name":"Wieschhoff, Christian"},{"first_name":"Chantal","last_name":"Theile-Rasche","full_name":"Theile-Rasche, Chantal"},{"full_name":"Wang, Fuzeng","first_name":"Fuzeng","last_name":"Wang"},{"last_name":"Prib","first_name":"Michael","full_name":"Prib, Michael"},{"full_name":"Moldt, Viktoria Daniela Dorothea","first_name":"Viktoria Daniela Dorothea","last_name":"Moldt"},{"id":"194","first_name":"Guido","last_name":"Grundmeier","full_name":"Grundmeier, Guido"},{"last_name":"Salas","first_name":"Nieves López","full_name":"Salas, Nieves López"},{"orcid":"0000-0002-8684-273X ","last_name":"de los Arcos de Pedro","first_name":"Maria Teresa","full_name":"de los Arcos de Pedro, Maria Teresa","id":"54556"}],"year":"2026","title":"Influence of negative ions on the stoichiometry and structure of carbon nitride films deposited by reactive magnetron sputtering","doi":"10.1063/5.0335780","language":[{"iso":"eng"}],"article_number":"243301"},{"date_created":"2026-06-25T12:16:32Z","department":[{"_id":"302"}],"type":"journal_article","citation":{"mla":"Voth, Sven, et al. “Role of Irradiance in Light-Activated In                    <sub>2</sub>                    O                    <sub>3</sub>                    Gas Sensors: Why More Light Is Not Always Better.” <i>ACS Sensors</i>, acssensors.6c01100, American Chemical Society (ACS), 2026, doi:<a href=\"https://doi.org/10.1021/acssensors.6c01100\">10.1021/acssensors.6c01100</a>.","bibtex":"@article{Voth_Zhao_Baier_Glass_Elgabarty_Sandberg_Grundmeier_Tiemann_Smått_Anttu_et al._2026, title={Role of Irradiance in Light-Activated In                    <sub>2</sub>                    O                    <sub>3</sub>                    Gas Sensors: Why More Light Is Not Always Better}, DOI={<a href=\"https://doi.org/10.1021/acssensors.6c01100\">10.1021/acssensors.6c01100</a>}, number={acssensors.6c01100}, journal={ACS Sensors}, publisher={American Chemical Society (ACS)}, author={Voth, Sven and Zhao, Zhenyu and Baier, Dominik and Glass, Alexandra and Elgabarty, Hossam and Sandberg, Oskar J. and Grundmeier, Guido and Tiemann, Michael and Smått, Jan-Henrik and Anttu, Nicklas and et al.}, year={2026} }","ama":"Voth S, Zhao Z, Baier D, et al.

By immobilizing the glycopeptide antibiotic vancomycin on DONs, DON binding to Gram‐positive and Gram‐negative bacteria can be facilitated. Here, we investigate how this multivalent binding is affected by the number and arrangement of the vancomycin modifications on two‐dimensional DONs. We find that for both Gram‐positive\r\n                    <jats:italic>Bacillus subtilis</jats:italic>\r\n                    and Gram‐negative\r\n                    <jats:italic>Escherichia coli</jats:italic>\r\n                    , binding increases with the number of vancomycin modifications per DON.

Interestingly, for both bacteria, the total number of vancomycin modifications appears to be more important than their arrangement, as DONs with 18 vancomycin molecules on one side show similar binding as DONs with 18 vancomycin molecules distributed over both sides. This enables the attachment of multiple probe molecules to the vancomycin‐free side of the DONs for enhancing detection efficiency without compromising binding affinity. These results may thus provide guidelines for the design and synthesis of vancomycin‐modified DONs for antimicrobial drug delivery and pathogen detection.\r\n                  </jats:p>"}],"language":[{"iso":"eng"}],"article_number":"e70436","doi":"10.1002/cbic.70436","author":[{"last_name":"Coşkuner Leineweber","first_name":"Özge","full_name":"Coşkuner Leineweber, Özge"},{"full_name":"Hofmann, Ulrike","last_name":"Hofmann","first_name":"Ulrike"},{"id":"194","full_name":"Grundmeier, Guido","first_name":"Guido","last_name":"Grundmeier"},{"last_name":"Zhang","first_name":"Yixin","full_name":"Zhang, Yixin"},{"id":"48864","last_name":"Keller","orcid":"0000-0001-7139-3110","first_name":"Adrian Clemens","full_name":"Keller, Adrian Clemens"}],"publication_identifier":{"issn":["1439-4227","1439-7633"]},"title":"Vancomycin‐Mediated Binding of DNA Origami Nanostructures to Gram‐Positive and Gram‐Negative Bacteria","year":"2026","intvolume":"        27","date_updated":"2026-06-30T13:01:42Z","publication_status":"published"},{"file":[{"file_id":"66669","content_type":"application/pdf","relation":"main_file","date_updated":"2026-08-06T06:55:55Z","file_name":"Keller_nai26.pdf","file_size":278638,"access_level":"open_access","date_created":"2026-08-06T06:55:55Z","creator":"adke"}],"date_created":"2026-08-06T06:56:02Z","type":"journal_article","department":[{"_id":"302"}],"issue":"6","publication":"Nucleic Acid Insights","abstract":[{"lang":"eng","text":"Over the last few decades, a large variety of nucleic acid‑based therapeutic approaches and drug formulations have been developed in the lab, tested in the clinic, and brought to market, ranging from antisense oligonucleotides (ASOs) and siRNAs to aptamer inhibitors and mRNA vaccines, with DNA and RNA nanostructure therapeutics already looming on the horizon. However, being susceptible toward hydrolysis, oxidation, non‑specific binding, and nuclease digestion, unmodified nucleic acids are rapidly degraded in vivo, resulting in poor therapeutic performance. Therefore, several stabilization strategies have been developed in order to protect those fragile molecules against adverse conditions during storage and in the body, while simultaneously accommodating their various mechanisms of action such as cellular uptake, target binding, or translation. These strategies include chemical modifications at the nucleoside level, complexation with proteins and polymers, and encapsulation in lipid nanoparticles (LNPs). Despite this variety of available methods, the field still faces many challenges, and this issue aims to provide an overview of the ongoing efforts to enhance the stability of therapeutic nucleic acids."}],"language":[{"iso":"eng"}],"doi":"10.18609/nai.2026.055","year":"2026","title":"Ongoing efforts to enhance stability","author":[{"full_name":"Keller, Adrian Clemens","last_name":"Keller","orcid":"0000-0001-7139-3110","first_name":"Adrian Clemens","id":"48864"}],"date_updated":"2026-08-06T06:59:39Z","intvolume":"         3","oa":"1","file_date_updated":"2026-08-06T06:55:55Z","citation":{"short":"A.C.

In this study, bioactive curcumin (CUM) derivatives were synthesized in a continuously operated microfluidic reactor (MFR), using piperidine-based polymeric networks as catalysts. Piperidine methacrylate and piperidine acrylate were synthesized and subsequently copolymerized with complementary monomers (MMA or DMAA) and crosslinkers (EGDMA or MBAM) via photopolymerization, yielding different polymeric networks. Initially, batch reactions were optimized for the organo-catalytic Knoevenagel condensation between CUM and 4-nitrobenzaldehyde, under various conditions, in the presence of polymer networks. Conversion was assessed using offline 1H NMR spectroscopy, revealing an increase in conversion with enhanced swelling properties of the polymer networks, which facilitated greater accessibility of catalytic sites. In continuous-flow MFR experiments, optimized polymer gel dots exhibited superior catalytic performance, achieving a conversion of up to 72%, compared to other compositions. This improvement was attributed to the enhanced swelling in the reaction mixture (DMSO/methanol, 7:3 v/v) at 40 °C over 72 h. Furthermore, the MFR system enabled the efficient synthesis of a series of CUM derivatives, demonstrating significantly higher conversion rates than traditional batch reactions. Notably, while batch reactions required 90% catalyst loading in the gel, the MFR system achieved a comparable or superior performance with only 50% catalyst, resulting in a higher turnover number.

However, the challenge is to develop active polymers that exhibit an antimicrobial effect and are compatible with human cells. Different studies aiming for biocidal polymers active in soluble mode, focused on the ratio of cationic to hydrophobic groups, while only marginal knowledge is available for immobilized components. Here a strong hydrophilic electrolyte 4‐vinylbenzyltrimethylammonium chloride (TMA) is chosen as the cationic component. The block composition of the polycationic segment is modified with styrene (Sty) regarding the amphiphilic balance. To adsorb such polymers onto titanium surfaces they are equipped with a polyphosphonic acid anchor block by sequential reversible‐addition‐fragmentation chain‐transfer polymerization (RAFT) polymerization. The polymer composition affected the wetting behavior of adsorbed coatings with water contact angles ranging from 17° to 72°, while zetapotential measurements confirmed high extent of positive charges for all adsorbed polymer coatings. The fundamentally modified block composition resulted in significantly improved cytocompatibility. Antimicrobial efficacy in early bacterial adhesion is still retained from slightly antiadhesive coatings to combined antiadhesive/biocidal activity depending on Sty/TMA ratio in random polymers while a block copolymer revealed lowest antimicrobial effect.</jats:p>"}],"citation":{"short":"C.

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>"}],"date_created":"2025-05-08T07:17:29Z","department":[{"_id":"302"}],"type":"journal_article","publication_identifier":{"issn":["2731-9229"]},"author":[{"full_name":"Pothineni, Bhanu Kiran","last_name":"Pothineni","first_name":"Bhanu Kiran"},{"last_name":"Barner","first_name":"Jörg","full_name":"Barner, Jörg"},{"id":"194","full_name":"Grundmeier, Guido","last_name":"Grundmeier","first_name":"Guido"},{"full_name":"Contreras, David","last_name":"Contreras","first_name":"David"},{"full_name":"Castro, Mario","first_name":"Mario","last_name":"Castro"},{"id":"48864","last_name":"Keller","orcid":"0000-0001-7139-3110","first_name":"Adrian","full_name":"Keller, Adrian"}],"title":"Rapid assembly of highly ordered DNA origami lattices at mica surfaces","year":"2025","intvolume":"        20","date_updated":"2025-05-08T07:17:54Z","publication_status":"published","language":[{"iso":"eng"}],"article_number":"77","doi":"10.1186/s11671-025-04254-2","citation":{"short":"B.K.
