Supramolecular assemblies combining the improved biostability of non-natural compounds with the complex membrane-attacking mechanisms of natural peptides are promising alternatives to conventional antibiotics. However, for such compounds the direct visual insight on antibacterial action is still lacking. Here we employ a design strategy focusing on an inducible assembly mechanism and utilized electron microscopy (EM) to follow the formation of supramolecular structures of lysine-rich heterochiral β 3 -peptides, termed lamellin-2K and lamellin-3K, triggered by bacterial cell surface lipopolysaccharides. Combined molecular dynamics simulations, EM and bacterial assays confirmed that the phosphate-induced conformational change on these lamellins led to the formation of striped lamellae capable of incising the cell envelope of Gram-negative bacteria thereby exerting antibacterial activity. Our findings also provide a mechanistic link for membrane-targeting agents depicting the antibiotic mechanism derived from the in-situ formation of active supramolecules.}, year = {2024}, eissn = {2041-1723}, orcid-numbers = {Wacha, András Ferenc/0000-0002-9609-0893; Szabó, Csenge Lilla/0000-0002-6508-3439; Bodor, Andrea/0000-0002-7422-298X; Horváti, Kata/0000-0003-4092-6011; Gyulai, Gergő/0000-0002-1352-2014; Bősze, Szilvia/0000-0001-9555-699X; Jezsó, Bálint/0000-0002-1306-4797; Tóth, Judit/0000-0002-0965-046X; Varga, Zoltán/0000-0002-5741-2669; Mándity, István/0000-0003-2865-6143} } @article{MTMT:34762097, title = {Effect of Non‐Thermal Sulfur Hexafluoride Cold Plasma Modification on Surface Properties of Polyoxymethylene}, url = {https://m2.mtmt.hu/api/publication/34762097}, author = {Chodkowski, Michał and Terpiłowski, Konrad and Románszki, Loránd and Klébert, Szilvia and Mohai, Miklós and Károly, Zoltán}, doi = {10.1002/cphc.202300709}, journal-iso = {CHEMPHYSCHEM}, journal = {CHEMPHYSCHEM: A EUROPEAN JOURNAL OF CHEMICAL PHYSICS AND PHYSICAL CHEMISTRY}, volume = {25}, unique-id = {34762097}, issn = {1439-4235}, abstract = {X‐ray photoelectron spectroscopy was employed to reveal the differences in the chemical structure of the topmost layer after plasma modification.

Infrared reflective coatings can keep objects cooler and have significant benefits in a wide variety of application by reflecting infrared light and decreasing heat, reducing operating costs, improving energy efficiency in buildings and vehicles, and extending an objects’ lifespan. The main aim of our research was to develop coatings in a RAL7016 Anthracite grey color with minimum heat adsorption in the infrared wavelength range. This was achieved using a combination of infrared transparent and infrared reflective pigment built-in coatings applied on two primers: white and black. Infrared reflectivity or transparency, as well as surface temperature, was investigated as a function of the composition and concentration of pigments. These coatings were characterized by chromatic parameters, by total solar and infrared solar reflectance in the UV, visible, and infrared wavelength range, and by heat reflection. Among the coatings developed, two produced very effective controls for infrared reflectance and transparency, and they could control heat reflectance, resulting in a significant decrease in surface temperature.}, year = {2023}, eissn = {2076-3417}, orcid-numbers = {Trif, László/0000-0002-3960-1829} } @article{MTMT:34373745, title = {Determination of Electrode Kinetics Parameters from Dynamic Electrochemical Impedance Spectroscopy Measurements via Potential-Program Invariant Functions}, url = {https://m2.mtmt.hu/api/publication/34373745}, author = {Pajkossy, Tamás}, doi = {10.1021/acs.jpclett.3c02810}, journal-iso = {J PHYS CHEM LETT}, journal = {JOURNAL OF PHYSICAL CHEMISTRY LETTERS}, volume = {14}, unique-id = {34373745}, issn = {1948-7185}, year = {2023}, pages = {10599-10608} } @article{MTMT:34213219, title = {Effect of heat treatment on the structure of self-assembled undecenyl phosphonic aicd layers developed on different stainless steel surfaces}, url = {https://m2.mtmt.hu/api/publication/34213219}, author = {Kocsisné Pfeifer, Éva and Mink, János and Gyurika, István Gábor and Telegdi, Lászlóné}, doi = {10.33927/hjic-2023-12}, journal-iso = {HUNG J IND CHEM}, journal = {HUNGARIAN JOURNAL OF INDUSTRY AND CHEMISTRY}, volume = {51}, unique-id = {34213219}, issn = {0133-0276}, year = {2023}, eissn = {2450-5102}, pages = {7-14}, orcid-numbers = {Kocsisné Pfeifer, Éva/0000-0001-8956-1856; Gyurika, István Gábor/0000-0003-3442-455X} } @article{MTMT:34135928, title = {Comparative Analysis of pH and Target-Induced Conformational Changes of an Oxytetracycline Aptamer in Solution Phase and Surface-Immobilized Form}, url = {https://m2.mtmt.hu/api/publication/34135928}, author = {Jakab, Kristóf and Melios, Nikitas and Tsekenis, George and Shaban, Abdul and Horváth, Viola and Keresztes, Zsófia}, doi = {10.3390/biom13091363}, journal-iso = {BIOMOLECULES}, journal = {BIOMOLECULES}, volume = {13}, unique-id = {34135928}, issn = {2218-273X}, abstract = {To date, numerous aptamer-based biosensing platforms have been developed for sensitive and selective monitoring of target analytes, relying on analyte-induced conformational changes in the aptamer for the quantification of the analyte and the conversion of the binding event into a measurable signal. Despite the impact of these conformational rearrangements on sensor performance, the influence of the environment on the structural conformations of aptamers has rarely been investigated, so the link between parameters directly influencing aptamer folding and the ability of the aptamer to bind to the target analyte remains elusive. Herein, the effect a number of variables have on an aptamer’s 3D structure was examined, including the pH of the buffering medium, as well as the anchoring of the aptamer on a solid support, with the use of two label-free techniques. Circular dichroism spectroscopy was utilized to study the conformation of an aptamer in solution along with any changes induced to it by the environment (analyte binding, pH, composition and ionic strength of the buffer solution), while quartz crystal microbalance with dissipation monitoring was employed to investigate the surface-bound aptamer’s behavior and performance. Analysis was performed on an aptamer against oxytetracycline, serving as a model system, representative of aptamers selected against small molecule analytes. The obtained results highlight the influence of the environment on the folding and thus analyte-binding capacity of an aptamer and emphasize the need to deploy appropriate surface functionalization protocols in sensor development as a means to minimize the steric obstructions and undesirable interactions of an aptamer with a surface onto which it is tethered.}, year = {2023}, eissn = {2218-273X}, orcid-numbers = {Jakab, Kristóf/0000-0001-9326-7457; Tsekenis, George/0000-0002-5780-1074; Shaban, Abdul/0000-0002-6365-0268; Horváth, Viola/0000-0003-1014-7930; Keresztes, Zsófia/0000-0002-1126-4779} } @article{MTMT:34135710, title = {Anticorrosion activity of Phosphonic acid amphiphile in self-assembled molecular layer}, url = {https://m2.mtmt.hu/api/publication/34135710}, author = {Kocsisné Pfeifer, Éva and Gyurika, István Gábor and Telegdi, Lászlóné}, doi = {10.17675/2305-6894-2023-12-3-25}, journal-iso = {INTJ CORROS SCALE INHIB}, journal = {INTERNATIONAL JOURNAL OF CORROSION AND SCALE INHIBITION}, volume = {12}, unique-id = {34135710}, issn = {2305-6894}, year = {2023}, pages = {1261-1274}, orcid-numbers = {Kocsisné Pfeifer, Éva/0000-0001-8956-1856; Gyurika, István Gábor/0000-0003-3442-455X} }
