Electrochemical sensing of strontium ions cyclic voltammetry and investigation of rosemary extract's effects on their behavior: Antibacterial properties of rosemary extract and molecular docking analysis for potential COVID-19 therapeutic benefits

Abstract

This work presents an electrochemical sensing for the estimation of strontium ions by cyclic voltammetry and studies its electrochemical behavior in the presence and absence of rosemary using 18 an Karat Gold working electrode in 0.1 M KBr at 295.15 K. The potential therapeutic effects of carnosol and carnosic acid against COVID-19 were explored through molecular docking analysis, suggesting their antiviral effects. The results showed that the obtained cyclic voltammograms showed well-defined redox peaks, and the peak current was found to increase linearly with increasing strontium chloride concentration. Rosemary has been shown to have antioxidant properties, which affect the redox behavior of strontium ions, leading to changes in the peak current and potential observed. SrCl2 solution has higher oxygen solubility and is useful in various industries. Additionally, plant extract showed inhibition of the growth of Gram-positive and Gram-negative bacteria due to its antibacterial activity. Overall, this research offers a promising electrochemical approach for measuring strontium ions and, the antibacterial activity of the Rosemary extract and reveals the potential therapeutic benefits of it against COVID-19.
