Influence of MWCNT Concentration on Antibacterial and Simultaneous Electrochemical Sensing of Ascorbic Acid and Paracetamol for Ag-Doped TiO2 Composites
In the present work, a straightforward approach was adopted to synthesize concentration-dependent multiwall carbon nanotubes with silver-doped titanium oxide (Ag-TiO2) composites. The antibacterial activity was examined against Gram-positive and Gram-negative bacteria, increasing from 12.5 to 16.5 mm for S. aureus, 20.5 to 26 mm for C. jejuni, and 19.5 to 25.5 mm for V. cholerae, incorporating 5% and 10% MWCNTs with Ag-TiO2, respectively. An Ag-TiO2-10% MWCNTs-GCE system was developed for the simultaneous detection of ascorbic acid (AA) and paracetamol (PA). Under optimal conditions, the sensor demonstrates linearity for AA (0.5–300 µM) and PA (0.01–500 µM) (n = 3), respectively. The corresponding detection limits for AA and PA were 0.038 and 0.008 μM. This electrochemical sensor exhibits tremendous promise for a variety of medical applications, particularly in AA and PA monitoring, and offers a straightforward and extremely sensitive approach for detecting AA and PA in human serum samples and pharmaceutical samples.
期刊介绍：
Electrocatalysis is cross-disciplinary in nature, and attracts the interest of chemists, physicists, biochemists, surface and materials scientists, and engineers. Electrocatalysis provides the unique international forum solely dedicated to the exchange of novel ideas in electrocatalysis for academic, government, and industrial researchers. Quick publication of new results, concepts, and inventions made involving Electrocatalysis stimulates scientific discoveries and breakthroughs, promotes the scientific and engineering concepts that are critical to the development of novel electrochemical technologies.
Electrocatalysis publishes original submissions in the form of letters, research papers, review articles, book reviews, and educational papers. Letters are preliminary reports that communicate new and important findings. Regular research papers are complete reports of new results, and their analysis and discussion. Review articles critically and constructively examine development in areas of electrocatalysis that are of broad interest and importance. Educational papers discuss important concepts whose understanding is vital to advances in theoretical and experimental aspects of electrochemical reactions.
