Electrochemical oxidation of 2’-deoxyguanosine-5’-triphosphate (dGTP) was investigated on the ionic liquid modified carbon paste microelectrode by cyclic voltammetry in this paper. The carbon ionic liquid microelectrode (mCILE) was prepared with ionic liquid 1-ethyl-3-methylimidazolium ethylsulfate ([Emim][EtOSO3]) as the modifier. Then the electrochemical process of dGTP on the mCILE was recor...
The improvement of electrochemical detection of meloxicam is presented by modification of a glassy carbon electrode with anionic layer of cysteic acid providing electrostatic accumulation of the analyte onto the electrode surface. The modification formed by electrochemical oxidation of L-cysteine was performed by cycling potential in cysteine solution. The anodic peak current obtained at + 1.08...
nanotechnology is a general term which is related with field of all advanced science term that generally predicates with all modern technologies which consider nanoscales. improvement in the quality of products by adding some nanoparticles and study of their behavior in the presence of these nanoparticles have been obtained in many researches. on the other hand numerous demands for sowing ...
with the aim of obtaining information about drug-drug interaction (ddi) between acetaminophen and some of antidepressant drugs (fluoxetine, sertraline and nortriptyline), in the present work we studied the electrochemical oxidation of acetaminophen (paracetamol) in the presence of these drugs by means of cyclic voltammetry and controlled-potential coulometry. the reaction between n-acetyl-p-ben...
the voltammetric performance of edge-plane pyrolytic graphite (epg) electrode via adsorptive stripping voltammetry was investigated for study of the electrochemical behavior of omeprazole (omz) in aqueous solution. the results revealed that the oxidation of omz is an irreversible ph-dependent process that proceeds with the transfer of one electron and one proton in an adsorption-controlled mech...
Screening of colorectal cancer is crucial for early stage diagnosis and treatment. Detection of volatile organic compounds (VOCs) of the metabolome present in exhaled breath is a promising approach to screen colorectal cancer (CRC). Various forms of volatile organic compounds (VOCs) that show the definitive signature for the different diseases including cancers are present in exhale breathe. Am...
Current transient evolution and in situ electrochemical AFM were used to study the initial stages of growth of electrochemically deposited nickel cobalt hydroxide films for energy storage applications. Current transients were taken at constant potentials, from -700 mV to -1000 mV, with a step of 50 mV. The current transients were fitted with three different nucleation models: Scharifker-Hill, S...
After 35 years the hunt for improved anthracycline antibiotics is unabated but has yet to achieve the levels of clinical success desired. Electrochemical techniques provide a large amount of kinetic and thermodynamic information, but the use of such procedures is hindered by issues of sensitivity and selectivity. This work demonstrates how by harnessing the mechanism of catalytic reduction of o...
Triazinedithiol polymeric nanofilm was prepared on a pure aluminum surface by electrochemical polymerization of AF17N. The mechanism of the process was proposed and electrochemical polymerization parameters were investigated. The triazinedithiol polymeric nanofilm had notable lubricity, high dielectric property and superhydrophobic property due to the allyl and fluoro alkyl groups in the AF17N ...
The synthesis of a new series of tetrathiafulvalene (TTF) and pi-extended TTF (exTTF) disulfides and the electrochemical properties of self-assembled monolayers derived from these compounds are described. When the intermediate bromides 3 and 7 were reacted with thiourea, followed by basic hydrolysis, the expected thiol formation was not observed and only disulfides were obtained. A mechanism is...
