摘要：

In this study, commercial graphene ink has been used as a cost-effective modifier for glassy carbon electrode (GCE) surface modification. The excellent conductivity and defects triggered electrocatalytic property of the graphene ink showed a superior performance in electrochemical sensing. Galantamine, an alkaloid isolated from Lycoris, has been selected as an analyte for evaluating the graphene ink-modified GCE. A clear signal enhancement with reduction of overpotential was observed using a GCE after a simple graphene ink surface modification process. A linear detection range from 20 mu M to 180 mu M of galantamine was recorded on the proposed electrode with a low limit of detection of 4.1 mu M.
