Abstract: The "grafting from" synthesis of core-shell molecularly imprinted polymer nanoparticles (Ser-MIP@SiO2 NPs) has been applied to the development of an electrochemical sensor for Serotonin. Ser-MIP@SiO2 NPs have been synthesized on preformed SiO2 nanobeads by surface imprinting via reversible additionfragmentation chaintransfer (RAFT) polymerization. After polymerization, the reductive aminolysis of dithioesther end group has been carried out. Then MIP-nanoparticles were subsequently characterized by ATR-FTIR, TGA, TEM and XPS. The entrapment of core-shell Ser-MIP@SiO2 NPs by the electropolymerization of PEDOT in an upside-down electrochemical cell has been investigated. Under selected conditions, results in sensing application for Serotonin are presented
