Abstract We report the fabrication of a highly sensitive dopamine biosensor based on entrapment tyrosinase into CaCO 3 nanoparticles at Multiwalled Carbon Nanotube (MWCNT) electrodes. acts as host matrix for and MWCNT provides porous conductive network enhancing enzyme immobilization electrochemical transduction reaction by boosting amplification phenomenon involved in biosensing catechol dopamine. The comparison performance ‐tyrosinase electrodes with without film clearly indicates...
Six derivatives of 4-(azulen-1-yl)-2,6-divinylpyridine were the subject experimental determination oxidation and reduction potentials being reported elsewhere. In this paper, a computational study was employed in order to obtain function structure for these potentials. The geometry optimized at three theory levels (MMFF94, B3LYP M06), following analysis conducted with separately saved optimum each instance. Two families molecular descriptors (FMPI EChP) used derive structure-based...
The present work is connected to the study of electrode conditioning issues for chemically modified electrodes (CMEs) prepared based on 2,6-bis((E)-2-(thiophen-2-yl)vinyl)-4-(5-isopropyl- 3,8-dimethylazulen-1-yl) pyridine (L). L irreversibly electrooxidized polymers leading L-CMEs. recognition experiments are final test chosen parameters (electropolymerization potential and charge in controlled electrolysis (CPE), anodic limit overoxidation cycles (OC), number OC, equilibration (EC), EC, pH...
