Determination of Anthracene on Ag-Au Alloy Nanoparticles/Overoxidized-Polypyrrole Composite Modified Glassy Carbon Electrodes
Mailu, Stephen N.; Waryo, Tesfaye T.; Ndangili, Peter M.; Ngece, Fanelwa R.; Baleg, Abd A.; Baker, Priscilla G.; Iwuoha, Emmanuel I. (Molecular Diversity Preservation International, 2010)A novel electrochemical sensor for the detection of anthracene was prepared by modifying a glassy carbon electrode (GCE) with over-oxidized polypyrrole (PPyox) and Ag-Au (1:3) bimetallic nanoparticles (Ag-AuNPs). The ... -
Electronics of Conjugated Polymers (I): Polyaniline
Molapo, Kerileng M.; Ndangili, Peter M.; Ajayi, Rachel F.; Mbambisa, Gcineka; Mailu, Stephen M.; Njomo, Njagi; Masikini, Milua; Baker, Priscilla; Iwuoha, Emmanuel I. (International Journal of ELECTROCHEMICAL SCIENCE, 2012-12)Conducting polymers have elicited much interest among researchers because of their reasonably good conductivity, stability, ease of preparation, affordability and redox properties compared to other organic compounds. In ... -
Impedimetric Response of a Label-Free Genosensor Prepared on a 3-Mercaptopropionic Acid Capped Gallium Selenide NanocrystalModified Gold Electrode
Ndangili, Peter M.; Jijana, Abongile N.; Olowu, Rasaq A.; Mailu, Stephen N.; Ngece, Fanelwa R.; Williams, Avril; Waryo, Tesfaye T.; Baker, Priscilla G.L.; Iwuoha, Emmanuel I. (2011)Biocompatible and water soluble 3-mercaptopropionic acid cappedgallium selenide nanocrystals were synthesized from hydrated gallium (III) perchlorate and selenide ions. The nanocrystals were non-fluorescent but ... -
Impedimetry and microscopy of electrosynthetic poly(propylene thiophenoimine)-co-poly(3,4 ethylene dioxythiophene) dendritic star copolymer
Olowu, Rasaq A; Williams, Avril; Ndangili, Peter M.; Ngece, Rachel F; Mailu, Stephen N; Baker, Priscilla; Iwuoha, Emmanuel (2011)The electrochemical impedance spectroscopy of generation 2 poly(propylene thiophenoimine)-co-poly(3,4 ethylene dioxythiophene) dendritic star copolymer (G2PPT-co-PEDOT) film was studied in LiClO4 solution. The results show ... -
Modulation of the interfacial electrochemistry of surfactant-functionalised polypyrrole chemical sensor systems
Iftikhar, Faiza J.; Baker, Priscilla G. L.; Baleg, Abdul M.; Ndangili, Peter M.; Mailu, Stephen N.; Iwuoha, Emmanuel I (Pergamon, 2011)The redox properties of electro-polymerized polypyrrole (Ppy) doped with different surfactants were studied in acid medium. It was found out that the addition of different surfactants affect the redox properties as evidenced ...
