Abstract
Background:
Carbon-based nanomaterials, especially carbon nitride (C3N4) has attracted
tremendous interest in biosensor applications. Meanwhile, the mechanism of redox protein sensing
and related electrocatalytic reactions can provide a valid basis for understanding the process of biological
redox reaction.
Objective:
The aim of this paper is to construct a new electrochemical enzyme sensor to achieve direct
electron transfer of myoglobin (Mb) on CILE surface and display electrocatalytic reduction activity
to catalyze trichloroacetic acid (TCA) and H2O2.
Methods:
The working electrode was fabricated based on ionic liquid modified Carbon Paste Electrode
(CILE) and C3N4 nanosheets were modified on the CILE surface, then Mb solution was fixed
on C3N4/CILE surface and immobilized by using Nafion film. The as-prepared biosensor displayed
satisfactory electrocatalytic ability towards the reduction of TCA and H2O2 in an optimum pH 7.0
buffer solution.
Results:
The results indicated that C3N4 modified electrode retained the activity of the enzyme and
displayed quasi-reversible redox behavior in an optimum pH 7.0 buffer solution. The electrochemical
parameters of the immobilized Mb on the electrode surface were further calculated with the results of
the electron transfer number (n) as 1.27, the charge transfer coefficient (α) as 0.53 and the electrontransfer
rate constant (ks) as 3.32 s-1, respectively. The Nafion/Mb/C3N4/CILE displayed outstanding
electrocatalytic reduction activity to catalyze trichloroacetic acid and H2O2.
Conclusion:
The Nafion/Mb/C3N4/CILE displayed outstanding electrocatalytic reduction, which
demonstrated the promising applications of C3N4 nanosheet in the field electrochemical biosensing.

Abstract
The interactions between proteins and electrode surfaces are of fundamental importance in bioelectrochemistry, including photobioelectrochemistry. In order to optimise the interaction between electrode and redox protein, either the electrode or the protein can be engineered, with the former being the most adopted approach. This tutorial review provides a basic description of the most commonly used electrode materials in bioelectrochemistry and discusses approaches to modify these surfaces. Carbon, gold and transparent electrodes (e.g. indium tin oxide) are covered, while approaches to form meso- and macroporous structured electrodes are also described. Electrode modifications include the chemical modification with (self-assembled) monolayers and the use of conducting polymers in which the protein is imbedded. The proteins themselves can either be in solution, electrostatically adsorbed on the surface or covalently bound to the electrode. Drawbacks and benefits of each material and its modifications are discussed. Where examples exist of applications in photobioelectrochemistry, these are highlighted.

Abstract
A fast and non-destructive voltammetric method to detect cocaine in confiscated samples based on carbon paste electrode modified with methoxy-substituted N,N'-ethylene-bis(salcylideneiminato)uranyl(VI)complexes, [UO2(X-MeOSalen)(H2O)].H2O, where X corresponds to the positions 3, 4 or 5 of the methoxy group on the aromatic ring, is described. The electrochemical behavior of the modified electrode and the electrochemical detection of cocaine were investigated using cyclic voltammetry. Using 0.1 mol·L−1 KCl as supporting-electrolyte, a concentration-dependent, well-defined peak current for cocaine at 0.62 V, with an amperometric sensitivity of 6.25 × 104 μA·mol·L−1 for cocaine concentrations ranging between 1.0 × 10−7 and 1.3 × 10−6 mol·L−1 was obtained. Chemical interference studies using lidocaine and procaine were performed. The position of the methoxy group affects the results, with the 3-methoxy derivative being the most sensitive.
