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 ...
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 ...
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 ...
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. ...
