Novel Copper Oxide Nanostructure Propafenone Voltammetric Sensor

Novel Deliberately Sensitive and Selective Tetrahydrozoline Voltammetric Sensors Integrated with a Copper Oxide Nanoparticle/Zeolite Platform

“…Upon fortification of the printing ink with CuONPs, the THZ oxidation peak was amplified and shifted toward the cathodic direction due to the electrocatalytic effect of CuONPs. This electrocatalytic effect may be attributed to the presence of Cu (III)/Cu (II) redox transitions, which are able to oxidize the THZ molecule at the electrode surface. , The estimated results indicated duplication of the THZ peak current via incorporation of 1.0% CuONPs within the electrode matrix. Gradual enhancement of the peak performance was recorded at a higher modifier content to reach its maximum peak current at 5.0% CuONPs.…”

“…Recent research has been devoted to integration of electrochemical sensors with various nanostructures to enhance the sensing performance such as their selectivity, sensitivity, and response time. Several trials were performed to incorporate different metallic oxide nanostructures within the electrochemical sensor matrix. − As a common metallic oxide nanostructure, copper oxide nanoparticles (CuONPs) were utilized as a proper electrode modifier for electrochemical sensing of many pharmaceutically active compounds. − Zeolitic nanostructures showed promising characteristics such as shape, pore size, and high cation exchange capacity; therefore, they were reported as a recommended modifier for various electrochemical sensors in determining many biologically and pharmaceutically active compounds. − …”
