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 ... -
Electrochemical Aptasensor for Endocrine Disrupting 17β-Estradiol Based on a Poly(3,4-ethylenedioxylthiopene)-Gold Nanocomposite Platform
Olowu, Rasaq A.; Arotiba, Omotayo; Mailu, Stephen N.; Waryo, Tesfaye T.; Baker, Priscilla; Iwuoha, Emmanuel (Molecular Diversity Preservation International, 2010)A simple and highly sensitive electrochemical DNA aptasensor with high affinity for endocrine disrupting 17β-estradiol, was developed. Poly(3,4-ethylenedioxylthiophene) (PEDOT) doped with gold nanoparticles (AuNPs) was ... -

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 ... -
In - situ Electrochemical Synthesis, Microscopic and Spectroscopic Characterisations of Electroactive poly(2,5-dimethoxyaniline) – Multi-Walled Carbon Nanotubes Composite Films in Neutral Media
Masikini, Milua; Mailu, Stephen N.; Tsegaye, Abebaw; Ikpo, Chinwe O.; Njomo, NJagi; Waryo, Tesfaye T.; Baker, Priscilla G. L.; Iwuoha, Emmanuel I. (International Journal of ELECTROCHEMICAL SCIENCE, 2014-09-29)Poly(2,5- dimethoxyaniline)-multi-wall carbon nanotubes (PDMA-MWCNT) nanocomposite films were synthesised by in –situ electrochemical polymerisation. The films were characterised by cyclic voltammetry (CV), ultra–visible ...
