Abstract

The main aim of this study was to test the biopolymer polycaprolactone (PCL) as an electrode modifier for the electrochemical detection of dopamine (DA). PCL was chosen following a search for polymers with the appropriate geometry and functional groups for dopamine detection. The chemical structure...
