Carboxybetaine Modified Interface for Electrochemical Glycoprofiling of Antibodies Isolated from Human Serum
Bertok, Tomas; Sediva, Alena; Filip, Jaroslav; Ilcikova, Marketa; Kasak, Peter; Velic, Dusan; Jane, Eduard; Mravcová, Martina; Rovenský, Jozef; Kunzo, Pavol; Lobotka, Peter; Šmatko, Vasilij; Vikartovská, Alica; Tkac, Jan... more authors ... less authors ( American Chemical Society , 2015 , Article)Impedimetric lectin biosensors capable of recognizing two different carbohydrates (galactose and sialic acid) in glycans attached to antibodies isolated from human serum were prepared. The first step entailed the modification ... -
Glycoprofiling of cancer biomarkers: Label-free electrochemical lectin-based biosensors
Pihíková, Dominika; Kasák, Peter; Tkac, Jan ( De Gruyter , 2015 , Article)Glycosylation of biomolecules is one of the most prevalent post- and co-translational modification in a human body, with more than half of all human proteins being glycosylated. Malignant transformation of cells influences ... -
Graphene as a signal amplifier for preparation of ultrasensitive electrochemical biosensors
Filip, Jaroslav; Kasák, Peter; Tkac, Jan ( Springer-Verlag , 2015 , Article)Early diagnostics of diseases performed with minimal money and time consumption has become achievable due to recent advances in development of biosensors. These devices use biorecognition elements for selective interaction ... -
Tailoring electrocatalytic properties of Pt nanoparticles grown on Ti3C2Tx MXene surface
Filip, Jaroslav; Zavahir, Sifani; Lorencova, Lenka; Bertok, Tomas; Yousaf, Ammar Bin; Mahmoud, Khaled A.; Tkac, Jan; Kasak, Peter... more authors ... less authors ( Electrochemical Society, Inc. , 2019 , Article)In this work, the spontaneous and NaBH4-induced reduction of chloroplatinic acid on the surface of Ti3C2TX MXene was investigated to synthesize a hybrid PtNP-decorated MXene nanomaterial (MX-Pt) with potential as hydrogen ... -
Tandem osmotic engine based on hydrogel particles with antipolyelectrolyte and polyelectrolyte effect fuelled by both salinity gradient modes
Padmanabhan, Anjali Cheeramthodi; Han, Dong Suk; Zavahir, Sifani; Tkac, Jan; Kasak, Peter ( MDPI , 2021 , Article)In this study, we propose a new approach to attain energy by salinity gradient engines with pistons based on hydrogels possessing polyelectrolyte and antipolyelectrolyte effects in a tandem arrangement, providing energy ... -
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 ...
