Electropolymerization of Glycine at Carbon Paste Electrode and its Application for the Determination of Methyl Orange

A recently constructed polyglycine modified carbon paste electrode (PGMCPE) was employed to evaluate the electrochemical behavior of methyl orange (MO). The developed electrode was characterized by FESEM to understand the morphology of the modified electrode and bare carbon paste electrode (BCPE). The modified electrode exhibits an excellent electrochemical activity towards the oxidation of MO....

A Hydrogen Peroxide Sensor Prepared by Electropolymerization of Pyrrole Based on Screen-Printed Carbon Paste Electrodes

A disposable amperometric biosensor for commercial use to detect hydrogen peroxide has been developed. The sensor is based on screen-printed carbon paste electrodes modified by electropolymerization of pyrrole with horseradish peroxidase (HRP) entrapped. The facture techniques of fabricating the enzyme electrodes are suitable for mass production and quality control. The biosensor shows a linear...

Determination of Resveratrol by Using Carbon Paste Electrodes

Resveratrol (3,3,4’-trans-trihydroxystilbene) is a polyphenolic phytoalexin that is produced by several plants as response to stress attack like UV exposure or fungus and bacteria infections [1]. It shows a variety of biological activities such as protection against atherosclerosis and against cardiovascular diseases and anticarcinogenic properties [2]. In recent years resveratrol has enjoyed a...
