An electrochemical DNA biosensor developed on a nanocomposite platform of gold and poly(propyleneimine) dendrimer
Arotiba, Omotayo A.; Owino, Joseph; Songa, Everlyne; Hendricks, Nicolette; Waryo, Tesfaye T.; Jahed, Nazeem; Baker, Priscilla; Iwuoha, Emmanuel I. (MDPI, 2008)An electrochemical DNA nanobiosensor was prepared by immobilization of a 20mer thiolated probe DNA on electro-deposited generation 4 (G4) poly(propyleneimine) dendrimer (PPI) doped with gold nanoparticles (AuNP) as ... -
Electrochemical immunosensor based on polythionine/gold nanoparticles for the determination of Aflatoxin B1
Owino, Joseph H.O.; Arotiba, Omotayo A.; Hendricks, Nicolette; Songa, Everlyne; Jahed, Nazeem; Waryo, Tesfaye T.; Ngece, Rachel F.; Baker, Priscilla; Iwuoha, Emmanuel I. (MDPI, 2008)An aflatoxin B1 (AFB1) electrochemical immunosensor was developed by the immobilisation of aflatoxin B1-bovine serum albumin (AFB1-BSA) conjugate on a polythionine (PTH)/gold nanoparticles (AuNP)-modified glassy carbon ... -
Polyester sulphonic acid interstitial nanocomposite platform for peroxide biosensor
Al-Ahmed, Amir; Ndangili, Peter M.; Jahed, Nazeem; Baker, Priscilla; Iwuoha, Emmanuel I. (MDPI, 2009)A novel enzyme immobilization platform was prepared on a platinum disk working electrode by polymerizing aniline inside the interstitial pores of polyester sulphonic acid sodium salt (PESA). Scanning electron microscopy ...
