Squaraine Dye

The theoretical description for the chlorantraniliprole electrochemical determination, assisted by the hybrid composite of squaraine dye with Ag2O2 nanoparticles, has been described. The correspondent reaction mechanism has been proposed, and the correspondent mathematical model has been developed and analyzed by means of linear stability theory and bifurcation analysis. It has been shown that the chlorantraniliprole electrochemical anodic determination on high potential may be efficiently provided by silver (I, III) oxide nanoparticles, stabilized by the squaraine dye. On the other hand, the oscillatory and monotonic instability is also possible, being caused by DEL influences of the electrochemical stage.

<p>The theoretical description for 4-4´-dihydroxyazobenzene CoO(OH) – assisted electrochemical determination in the mushroom pulp, food, and biological liquids has been described. In this system, a squaraine dye is used as a Cobalt(III)oxyhydroxide stabilizer and electron transfer mediator. It is shown that, contrary to the large part of the systems with cobalt (III) oxyhydroxide, this system will behave more stably, providing an efficient diffusion-controlled process. On the other hand, the oscillatory and monotonic instabilities, although possible, are caused by the double electric layer influences of either chemical or electrochemical stage.</p>

For the first time, the system with anti-COVID19 drug umivenofir electrochemical determination, assisted by a Squaraine Dye – CoO(OH)/CoO2 composite, has been described theoretically. The mechanism contains hydrolysis, chemical, and electrochemical oxidation stages. The correspondent mathematical model has been developed and analyzed using linear stability theory and bifurcation analysis. Despite the branched character of the mechanism, the composite of Squaraine Dye with CoO(OH)/CoO2 may be an efficient electrode modifier for the umivenofir determination. However, the oscillatory behavior may be possible, but only because of double electric layer influences on the electrochemical stage.

For the first time, the remdesivir anti-COVID-19 drug electrochemical determination has been evaluated theoretically. In this work, an anodic process involving the Squaraine Dye – Ag2O2 composite has been evaluated. The mechanism of the electroanalytical process is branched, which implies relatively dynamic behavior. Nevertheless, the correspondent mathematical model analysis, made by linear stability theory and bifurcation analysis, confirms the composite electroanalytical efficiency as an electrode modifier.

In this work, a general theoretical description of the electrochemical determination of Sudan dyes by cathodic and anodic route has been made. Two mathematical models have been developed for each case, being, afterward, analyzed by means of linear stability theory and bifurcation analysis. It has been shown that in both cases, the systems are efficient from the electroanalytical point of view. The possibility for the oscillatory and monotonic instability has also been verified.
