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 ...

Bioaccumulation of total mercury in the earthworm Eisenia andrei

Shirley Le Roux; Priscilla Baker; Andrew Crouch (SpringerOpen, 2016)

Earthworms are a major part of the total biomass of soil fauna and play a vital role in soil maintenance. They process large amounts of plant and soil material and can accumulate many pollutants that may be present in ...

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; Iwuoha, Emmanuel I. (MDPI, 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 ...

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 ...

Electrochemical aptasensor for endocrine disrupting 17β-estradiol based on a poly(3,4-ethylenedioxylthiopene)-gold nanocomposite platform

Olowu, Rasaq A.; Mailu, Stephen N.; Waryo, Tesfaye T.; Baker, Priscilla; Iwuoha, Emmanuel I.; Arotiba, Omotayo A. (MDPI, 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 ...

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 ...
