Imprinted sol gel and nano materials as electrochemical sensor for sensitive determination of ranitidine Hojjatollah Lotfi Forushani Lotfi hojat@yahoo com September 17 2012 Department of Chemistry Isfahan University of Technology Isfahan 84156 83111 IranDegree M Sc Lanquage FarsiSupervisers Professor Behzad Rezaei E mail rezaei@cc iut ac irAdvisor Professor Ali A Ensafi E mail ensafi@cc iut ac irAbstractIn this study a novel molecularly imprinted electrochemical sensor for sensitive determination of ranitidine wasdeveloped Gold nanoparticles GNPs and multi walled carbon nanotubes MWCNTs were used forenhancement of electronic transmission and sensitivity The thin film of molecularly imprinted sol gel polymerswith specific binding sites for ranitidine was cast on modified pencil graphite electrode by electrochemicaldeposition method The resulting composite was characterized by electrochemical impedance spectroscopy EIS and cyclic voltammetric techniques CV The interaction between the imprinted sensor and target molecule wasobserved by measuring the current response of the oxidation reduction of the K3 Fe CN 6 as a probe on theelectrode Under the optimal experimental conditions the response peak current was linear to the concentrationof ranitidine in the range from 0 05 to 2 0 M and the detection limit was 15 nM This imprinted sensor wassuccessfully applied to the determination of ranitidine in human urine samples These results have revealed thatthe imprinted sensor fulfilled the selectivity sensitivity speed and simplicity requirements for ranitidinedetection and provided possibilities of clinical application in physiological fluids Keywords Molecularly imprinted polymer Electrochemical sensor Pencil graphite electrode Goldnanoparticles Multi walled carbon nanotubes Imprinted sol gel Ranitidine drug
