Screen printed graphite macroelectrodes for the direct electron transfer of cytochrome c.
We report the direct electrochemistry of cytochrome c at screen printed graphite electrodes which exhibits quasi-reversible voltammetric responses without the need for any chemical or electrochemical pre-treatment, use of mediators or nanomaterials. Through voltammetric studies and X-ray photoelectron spectroscopy (XPS) it is shown that carbonyl and carboxylic surface oxygenated species likely ...
متن کاملPreparation and biochemical characterisation of nanoconjugates of functionalized carbon nanotubes and cytochrome c
Objective(s): The present work deals with the preparation of nanobioconjugates based on the immobilization of cytochrome c (cyt c) on functionalized multi-wall carbon nanotubes (f-MWCNTs). The effect of the nanosupport and the immobilization procedure on the biochemical and structural characteristics of the immobilized protein was investigated. Methods: </strong...
متن کاملA New Sensor Based on Graphite Screen Printed Electrode Modified With Cu-Nanocomplex for Determination of Paracetamol
Paracetamol is a non-steroidal anti-inflammatory drug used as an antipyretic agent for the alternative to aspirin. Conversely, the overdoses of paracetamol can cause hepatic toxicity and kidney damage. Hence, the determination of paracetamol receives much more attention in biological samples and also in pharmaceutical formulations. Here, we report a rapid<span id="transmark" style="display: non...
متن کاملAn electrochemical acetaminophen sensor based on La3+/Co3O4 nanoflowers modified graphite screen printed electrode architecture
In this study, the La3+/Co3O4 nanoflowers were synthesized by co-precipitation method. The morphology of the La3+/Co3O4NFs were characterized using scanning electron microscopy (SEM), and were further used to modify the graphite screen printed electrode (GSPE). The electrochemical behavior of acetaminophen at La3+/Co<s...
