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:34008641, title = {Dual-Role Peptide with Capping and Cleavage Site Motifs in Nanoparticle-Based One-Pot Colorimetric and Electrochemical Protease Assay}, url = {https://m2.mtmt.hu/api/publication/34008641}, author = {Szabó, Tamás and Bakos, István and Csupor, Barbara and Jeerapan, Itthipon and Pekker, Péter and Mihály, Judith and Németh, Krisztina and Wang, Joseph and Keresztes, Zsófia}, doi = {10.1021/acsomega.3c00771}, journal-iso = {ACS OMEGA}, journal = {ACS OMEGA}, volume = {8}, unique-id = {34008641}, issn = {2470-1343}, year = {2023}, eissn = {2470-1343}, pages = {22556-22566}, orcid-numbers = {Szabó, Tamás/0000-0002-9506-6410; Jeerapan, Itthipon/0000-0001-8016-6411; Pekker, Péter/0000-0002-0463-0742; Keresztes, Zsófia/0000-0002-1126-4779} } @article{MTMT:33724042, title = {Corrosion Protection and Heat Resistance of Paints for Outdoor Use}, url = {https://m2.mtmt.hu/api/publication/33724042}, author = {Felhősi, Ilona and Molnárné Nagy, Lívia and Horváth, Szilvia and Pozman, Tamás and Bognár, János and Szabó, Tamás and Keresztes, Zsófia}, doi = {10.3390/ma16072753}, journal-iso = {MATERIALS}, journal = {MATERIALS}, volume = {16}, unique-id = {33724042}, abstract = {Innovative heat- and corrosion-resistant coating approaches, applicable in indirect-food-contact outdoor environments, have been developed. Two systems, a direct-to-metal single-layer, polysiloxane-based, oven-dried system and a bilayer, zinc phosphate active pigment-containing, ambient-cured system were developed to overcome the shortcomings of the traditional bilayer, zinc-rich primer-based heat-resistant surface-protective solutions for outdoor cooking equipment, such as barbecue grills. This case study aims to optimize the application conditions, measure and evaluate the impact of surface preparation and compare thermo-resistant and anticorrosive properties of different coating systems focusing on eco-efficiency. The anticorrosion efficiency of the coatings was characterized using salt-spray chamber corrosion tests and electrochemical impedance spectroscopy. The thermo-resistant character of the coatings was tested by cyclic and constant heat treatment, after which the physical integrity of the coatings was evaluated by optical microscopy. In the overall performance of the coatings, the roughening of the steel substrate surface and the thickness of the coatings were also considered as influential parameters. The study revealed that the newly developed coatings have superior anticorrosion performance to the usually applied Zn-rich coating. The Single-layered Coating has excellent corrosion resistance under certain conditions and has the advantage of fast layer application. The Bilayered Coating showed excellent heat- and corrosion-resistance properties even on a surface without sand-blasting.}, year = {2023}, eissn = {1996-1944}, orcid-numbers = {Felhősi, Ilona/0000-0003-1310-432X; Keresztes, Zsófia/0000-0002-1126-4779} } @article{MTMT:33062187, title = {EEG sensor system development consisting of solid polyvinyl alcohol–glycerol–NaCl contact gel and 3D-printed, silver-coated polylactic acid electrode for potential brain–computer interface use}, url = {https://m2.mtmt.hu/api/publication/33062187}, author = {Jakab, Kristóf and Csipor, J. and Ulbert, István and Keresztes, Zsófia and Mészáros, Gábor and Márton, Gergely}, doi = {10.1016/j.mtchem.2022.101085}, journal-iso = {MATER TODAY CHEM}, journal = {MATERIALS TODAY CHEMISTRY}, volume = {26}, unique-id = {33062187}, issn = {2468-5194}, year = {2022}, eissn = {2468-5194}, orcid-numbers = {Jakab, Kristóf/0000-0001-9326-7457; Ulbert, István/0000-0001-9941-9159; Keresztes, Zsófia/0000-0002-1126-4779} } @article{MTMT:31930849, title = {Advances in Electromagnetic Piezoelectric Acoustic Sensor Technology for Biosensor-Based Detection}, url = {https://m2.mtmt.hu/api/publication/31930849}, author = {Mészáros, Gábor and Akbarzadeh, Sanaz and De La Franier, Brian and Keresztes, Zsófia and Thompson, Michael}, doi = {10.3390/chemosensors9030058}, journal-iso = {CHEMOSENSORS}, journal = {CHEMOSENSORS}, volume = {9}, unique-id = {31930849}, year = {2021}, eissn = {2227-9040}, orcid-numbers = {Keresztes, Zsófia/0000-0002-1126-4779} } @article{MTMT:31873518, title = {Indirect electrochemical method for high accuracy quantification of protein adsorption on gold surfaces}, url = {https://m2.mtmt.hu/api/publication/31873518}, author = {Bakos, István and Vass, Ádám and Muckley, Eric S. and Ivanov, Ilia N. and Keresztes, Zsófia}, doi = {10.1016/j.elecom.2021.106961}, journal-iso = {ELECTROCHEM COMMUN}, journal = {ELECTROCHEMISTRY COMMUNICATIONS}, volume = {124}, unique-id = {31873518}, issn = {1388-2481}, year = {2021}, eissn = {1873-1902}, orcid-numbers = {Bakos, István/0000-0002-5715-0427; Vass, Ádám/0000-0002-8012-9511; Muckley, Eric S./0000-0001-7114-5424; Keresztes, Zsófia/0000-0002-1126-4779} } @article{MTMT:31782661, title = {Optimization Aspects of Electrodeposition of Photoluminescent Conductive Polymer Layer onto Neural Microelectrode Arrays}, url = {https://m2.mtmt.hu/api/publication/31782661}, author = {Marek, Tamás and Orbán, Gábor and Meszéna, Domokos and Márton, Gergely and Ulbert, István and Mészáros, Gábor and Keresztes, Zsófia}, doi = {10.1016/j.matchemphys.2020.124163}, journal-iso = {MATER CHEM PHYS}, journal = {MATERIALS CHEMISTRY AND PHYSICS}, volume = {260}, unique-id = {31782661}, issn = {0254-0584}, year = {2021}, eissn = {1879-3312}, orcid-numbers = {Orbán, Gábor/0000-0002-8513-626X; Meszéna, Domokos/0000-0003-4042-2542; Márton, Gergely/0000-0003-4359-0111; Ulbert, István/0000-0001-9941-9159; Keresztes, Zsófia/0000-0002-1126-4779} } @article{MTMT:31683012, title = {Plasmin determination based on enzymatic digestion of a β-casein layer at the air/water interface}, url = {https://m2.mtmt.hu/api/publication/31683012}, author = {Románszki, Loránd and Hianik, Tibor and Keresztes, Zsófia}, doi = {10.1016/j.colsurfa.2020.125786}, journal-iso = {COLLOID SURFACE A}, journal = {COLLOIDS AND SURFACES A : PHYSICOCHEMICAL AND ENGINEERING ASPECTS}, volume = {609}, unique-id = {31683012}, issn = {0927-7757}, year = {2021}, eissn = {1873-4359}, orcid-numbers = {Románszki, Loránd/0000-0002-6347-5228; Keresztes, Zsófia/0000-0002-1126-4779} }
