Electrochemical Investigation of Interfacial Properties of Ti3C2Tx MXene Modified by Aryldiazonium Betaine Derivatives
Lorencova, Lenka; Gajdosova, Veronika; Hroncekova, Stefania; Bertok, Tomas; Jerigova, Monika; Velic, Dusan; Sobolciak, Patrik; Krupa, Igor; Kasak, Peter; Tkac, Jan... more authors ... less authors ( Frontiers Media S.A. , 2020 , Article)For efficient and effective utilization of MXene such as biosensing or advanced applications, interfacial modification of MXene needs to be considered. To this end, we describe modification of Ti3C2Tx MXene by aryldiazonium-based ... -
Electrochemical performance of Ti3C2Tx MXene in aqueous media: towards ultrasensitive H2O2 sensing
Lorencova, Lenka; Bertok, Tomas; Dosekova, Erika; Holazova, Alena; Paprckova, Darina; Vikartovska, Alica; Sasinkova, Vlasta; Filip, Jaroslav; Kasak, Peter; MonikaJerigova; Velic, Dusan; Mahmoud, Khaled A.; Tkac, Jan... more authors ... less authors ( Elsevier Ltd , 2017 , Article)An extensive characterization of pristine and oxidized Ti3C2Tx (T: O, OH, F) MXene showed that exposure of MXene to an anodic potential in the aqueous solution oxidizes the nanomaterial forming TiO2 layer or TiO2 domains ... -
Glycomics of prostate cancer: updates
Tkac, Jan; Bertok, Tomas; Hires, Michal; Jane, Eduard; Lorencova , Lenka; Kasak, Peter... more authors ... less authors ( Taylor and Francis Ltd , 2019 , Article)Introduction: Prostate cancer (PCa) is a life-threatening disease affecting millions of men. The current best PCa biomarker (level of prostate-specific antigen in serum) lacks specificity for PCa diagnostics and this is ... -
Highly stable Ti3C2Tx (MXene)/Pt nanoparticles-modified glassy carbon electrode for H2O2 and small molecules sensing applications
Lorencova, L.; Lorencova, Lenka; Bertok, Tomas; Filip, Jaroslav; Jerigova, Monika; Velic, Dusan; Kasak, Peter; Mahmoud, Khaled A.; Tkac, Jan... more authors ... less authors ( Elsevier B.V. , 2018 , Article)© 2018 Elsevier B.V. Electrochemical performance of a 2D Ti3C2Tx (MXene, where T: [dbnd]O, –OH, –F) sheets modified with Pt nanoparticles (PtNPs) was investigated. The results showed that Ti3C2Tx/PtNP nanocomposite deposited ... -
