摘要：

A simple and sensitive electrochemical biosensor for acrylamide (AA) detection based on hemoglobin (Hb) entrapped in ionic liquid-carbon paste was constructed. The Hb-carbon ionic liquid paste electrode (Hb/CILPE) was studied and characterized by scanning electron microscopy (SEM) and electrochemical method. The surface passivation of the Hb/CILPE could be achieved by the addition of acrylamide molecule, which caused the lower current response value owing to the adduct formed by acrylamide and Hb as a result of the reaction between the α-NH2 g...
