Carboxybetaine Modified Interface for Electrochemical Glycoprofiling of Antibodies Isolated from Human Serum
( 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 ... -
Electrochemical performance of Ti3C2Tx MXene in aqueous media: towards ultrasensitive H2O2 sensing
( 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 ... -
Graphene as a signal amplifier for preparation of ultrasensitive electrochemical biosensors
( 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 ... -
Highly stable Ti3C2Tx (MXene)/Pt nanoparticles-modified glassy carbon electrode for H2O2 and small molecules sensing applications
( 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 ... -
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
( 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 ... -
Immobilization of concanavalin A lectin on a reduced graphene oxide-thionine surface by glutaraldehyde crosslinking for the construction of an impedimetric biosensor
( Elsevier B.V. , 2017 , Article)Lectins, which are proteins with selective affinity to glycans or glycoproteins, have been recognized as promising agents for the construction of devices for the detection of specific glycoproteins and for glycoprofiling. ... -
Nanotechnology in Glycomics: Applications in Diagnostics, Therapy, Imaging, and Separation Processes
( John Wiley and Sons Inc. , 2017 , Article Review)This review comprehensively covers the most recent achievements (from 2013) in the successful integration of nanomaterials in the field of glycomics. The first part of the paper addresses the beneficial properties of ... -
Novel analysis of glycan structures: Nanoscale approach
( Avestia Publishing , 2016 , Conference)Glycans are complex saccharide moieties covering all cell surfaces - presented on different biomolecules. Almost 75% of all proteins are glycosylated, and these glycans can form thousands of different structures.[1] Moreover, ... -
PH-Switchable Interaction of a Carboxybetaine Ester-Based SAM with DNA and Gold Nanoparticles
( American Chemical Society , 2017 , Article)We describe a self-assembled monolayer (SAM) on a gold surface with a carboxybetaine ester functionality to control the interaction between DNA and gold nanoparticles via pH. The negatively charged phosphate backbone of ... -
Progress in biocatalysis with immobilized viable whole cells: systems development, reaction engineering and applications
( Springer Netherlands , 2017 , Article Review)Viable microbial cells are important biocatalysts in the production of fine chemicals and biofuels, in environmental applications and also in emerging applications such as biosensors or medicine. Their increasing significance ... -
Simple, Reversible, and Fast Modulation in Superwettability, Gradient, and Adsorption by Counterion Exchange on Self-Assembled Monolayer
( American Chemical Society , 2016 , Article)A simple fabrication method for preparation of surfaces able to switch from superhydrophobic to superhydrophilic state in a reversible and fast way is described. A self-assembled monolayer (SAM) consisting of quaternary ...
