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 ... -
Glycoprofiling as a novel tool in serological assays of systemic sclerosis: A comparative study with three bioanalytical methods
Klukova, Ludmila; Bertok, Tomas; Petrikova, Miroslava; Sediva, Alena; Mislovicova, Danica; Katrlik, Jaroslav; Vikartovska, Alica; Filip, Jaroslav; Kasak, Peter; Andicsová-Eckstein, Anita; Mosnáček, Jaroslav; Lukáč, Jozef; Rovenský, Jozef; Imrich, Richard; Tkac, Jan... more authors ... less authors ( Elsevier , 2015 , Article)Systemic sclerosis (SSc) is an autoimmune disease seriously affecting patient’s quality of life. The heterogeneity of the disease also means that identification and subsequent validation of biomarkers of the disease is ... -
Immobilization of bilirubin oxidase on graphene oxide flakes with different negative charge density for oxygen reduction. The effect of GO charge density on enzyme coverage, electron transfer rate and current density
Filip, Jaroslav; Andicsova-Eckstein, Anita; Vikartovska, Alica; Tkac, Jan ( Elsevier Ltd , 2017 , Article)Previously we showed that an effective bilirubin oxidase (BOD)-based biocathode using graphene oxide (GO) could be prepared in 2 steps: 1. electrostatic adsorption of BOD on GO; 2. electrochemical reduction of the BOD-GO ... -
Mixed Zwitterion-Based Self-Assembled Monolayer Interface for Impedimetric Glycomic Analyses of Human IgG Samples in an Array Format
Bertok, Tomas; Dosekova, Erika; Belicky, Stefan; Holazova, Alena; Lorencova, Lenka; Mislovicova, Danica; Paprckova, Darina; Vikartovska, Alica; Plicka, Robert; Krejci, Jan; Ilcikova, Marketa; Kasak, Peter; Tkac, Jan... more authors ... less authors ( American Chemical Society , 2016 , Article)An impedimetric lectin biosensor for the detection of changes in the glycan structure of antibodies isolated from human serum is here correlated with the progression of rheumatoid arthritis (RA). The biosensor was built ... -
Ultrasensitive Ti3C2TX MXene/chitosan nanocomposite-based amperometric biosensor for detection of potential prostate cancer marker in urine samples
Hroncekova, Stefania; Bertok, Tomas; Hires, Michal; Jane, Eduard; Lorencova, Lenka; Vikartovska, Alica; Tanvir, Aisha; Kasak, Peter; Tkac, Jan... more authors ... less authors ( MDPI AG , 2020 , Article)Two-dimensional layered nanomaterial Ti3C2TX (a member of the MXene family) was used to immobilise enzyme sarcosine oxidase to fabricate a nanostructured biosensor. The device was applied for detection of sarcosine, a ...
