Surfactants used for dispersion of graphenes exhibit strong influence on electrochemical impedance spectroscopic response
We show here that electrochemical impedance spectroscopy response of graphene is dramatically influenced by presence/absence of surfactants. In many protocols for the production of graphene surfactants are employed in order ...
Graphene in biosensing
Biosensing is paramount for improving the quality of human life. Biosensors and biosensing protocols are able to detect a wide range of compounds, sensitively and selectively, with applications in security, health care for ...
Electrochemistry of folded graphene edges
There is enormous interest in the investigation of electron transfer rates at the edges of graphene due to possible energy storage and sensing applications. While electrochemistry at the edges and the basal plane of graphene ...
Graphene materials preparation methods have dramatic influence upon their capacitance
Graphene related materials are widely expected to play a major role as materials for the construction of supercapacitors. We demonstrate here that graphene oxides prepared by various well-established methods exhibit ...
Number of graphene layers exhibiting an influence on oxidation of DNA bases : analytical parameters
This article investigates the analytical performance of double-, few- and multi-layer graphene upon oxidation of adenine and guanine. We observed that the sensitivity of differential pulse voltammetric response of guanine ...
Voltammetry of carbon nanotubes and graphenes : excitement, disappointment, and reality
Voltammetry of carbon nanotubes and graphene underwent significant development in the first decade of the 21st century. The initial excitement concerning the performance of the new materials was replaced with increasing ...
