Then, Co(II) complex of salophen type Schiff base (CoL) was immobilized on these polymer coated electrode surfaces in acetonitrile containing 0.15 M LiClO4. The prepared modified surfaces were characterized by Cyclic Voltammetry, UV-Vis, SEM-EDAX and ICP-MS techniques. The electrocatalytic activity of modified electrodes was investigated on electrooxidation of Dopamine (DA) as biosensor application. One of the prepared modified electrodes showed good electrocatalytic effect on the oxidation of DA using Square Wave Voltammetry method (SWV). The oxidation peak current of DA increased linearly in the range of 0.2 mu M - 2 mM in pH 7 phosphate buffer solution at left perpendicular CoL right perpendicular immobilized pA modified Platinum electrode. Limit of Detection (LOD) was calculated as 0.1 mu M for DA determination.eninfo:eu-repo/semantics/closedAccesso-amino-benzyl alcoholelectropolymerizationSchiff Base metal compleximmobilizationelectrocatalytic investigationArticle485561WOS:000392342400011Q4
