Application on gold nanoparticles-dotted 4-nitrophenylazo graphene in a label-free impedimetric deoxynivalenol immunosensor
Sunday, Christopher Edozie; Masikini, Malua; Wilson, Lindsay; Rassie, Candice; Waryo, Tesfaye T.; Baker, Priscilla; Iwuoha, Emmanuel I. (MDPI, 2015)In this paper, we report a new concept to construct a label-free electrochemical inhibition-based immunosensor for the detection of the mycotoxin deoxynivalenol (DON) in cereal samples. The electrochemical impedance ... -
Aptameric recognition-modulated electroactivity of poly(4-styrenesolfonic acid)-doped polyaniline films for single-shot detection of tetrodotoxin
Fomo, Gertrude; Waryo, Tesfaye T.; Sunday, Christopher Edozie; Baleg, Abd A.; Baker, Priscilla; Iwuoha, Emmanuel I. (MDPI, 2015)The work being reported is the first electrochemical sensor for tetrodotoxin (TTX). It was developed on a glassy carbon electrodes (C) that was modified with poly(4-styrenesolfonic acid)-doped polyaniline film (PANI/PSSA). ...
