A novel electrochemical synthesis of poly-3-methylthiophene-γ-cyclodextrin film☆Application for the analysis of chlorpromazine and some neurotransmitters

The selective detection of dopamine at a polypyrrole film doped with sulfonated β-cyclodextrins

“…They also exhibit excellent biocompatibility and as a result have been incorporated into various dopamine sensors. For example, Izaoumen et al [22] and Bouchta et al [23] have used polymer films modified with neutral cyclodextrins and doped with perchlorate anions for the sensing of dopamine, while Alarcon-Angeles et al [24] have modified multiwall carbon nanotubes with ␤-cyclodextrins for the sensing of dopamine. The electrochemical synthesis of polypyrrole doped with sulfonated ␤-cyclodextrins has been reported by Temsamani et al [25], Bidan et al [26] and Reece et al [27].…”

Application of Conducting Polymers in Electroanalysis

“…It was found that the Pd nanoparticules modified by CPs electrodes (PbNPs, with average diameter of 60 nm , were electro-deposited by cyclic voltammetry method, scanning the potential between −0.25 and +0.65 V (vs Ag/AgCl) at a scan rate of 50 mV −1 ; 2.5 10 -3 mol L -1 PbCl 2 in 0.1 mol L -1 HClO 4 ) has the best analytical performance, contrary to that of PtNPs. Introduction of neutral ɣ-cyclodextrines into P3MeT doped hexafluorophosphate (Bouchta et al, 2005) and -cyclodextrines into PPy in the presence of perchlorate (Izaoumen et al, 2005) was described. Cyclodextrines (CDs) are cyclic oligosaccharides consisting of six, seven or eight glucose units called -, -and ɣ-cyclodextrins respectively.…”

Electrochemistry of Cyclodextrin Inclusion Complexes of Pharmaceutical Compounds

“…A functionalized stable film of poly-3-methylthiophene combined with -cyclodextrin (P3MT/ -CD) in tetrabutylammonium hexafluorophosphate/acetonitrile solution has been prepared and used as a sensor for dopamine, l-dopa and chlorpromazine [114]. A potentiostatic mode was employed for the film growth.…”
