Composite poly(dimethoxyaniline) electrochemical nanobiosensor for glufosinate and glyphosate herbicides
Songa, Everlyne Apiyo (University of the Western Cape, 2008)In this thesis, I present a simple, sensitive and low cost electrochemical nanobiosensor for quantitative determination of the herbicides glufosinate, glyphosate and its metabolite aminomethylphosphonic acid (AMPA). Firstly, ... -
Development of Schiff base electrochemical sensors for the evaluation of polycyclic aromatic hydrocarbons in aqueous medium
Ward, Meryck (University of the Western Cape, 2017)A novel monomer (N,N'-Bis-(1H-pyrrol-2-ylmethylene)-benzene-1,2-diamine-BPPD) was derived from the condensation reaction between o-phenylenediamine and a pyrrole derivative. The monomer was polymerized electrochemically ... -
Nanoparticulate of silver-modified poly (8-anilino-1-naphthalene sulphonic acid) nanobiosensor systems for the determination of Tuberculosis treatment drugs
Ngece, Rachel Fanelwa (University of the Western Cape, 2011)This study firstly reports the development and characterization of PVP-AgNPs, PANSA and PVPAgNPs/ PANSA nanocomposite on gold. AFM and TEM analyses revealed highly electroactive nanocomposites whose morphogy and properties ... -
Nanostructured polyamic acid electrocatalysts for reliable analytical reporting of sulphonamides as contaminants of emerging concern
Hamnca, Siyabulela (University of the Western Cape, 2019)Polyamic acid (PAA) nanostructured materials were successfully produced by electrochemical deposition and electrospinning using polyvinlypyrrolidone (PVP) as supporting polymer. Polyamic acid thin film and nanofibers were ... -
Polyamic acid composites for multiiple sensing applications in complex sample matrices
Hess, Euòdia Hallouise (2013)Polyamic acid-polypyrrole (PAA/PPy) composite films were prepared and characterised for the use as conducting platforms in the design of biosensor systems. The thin films were synthesised by electrochemical method from a ... -
Quantum dot sensitized estrogen receptor alpha-recombinant protein electrochemical biosensor for 17-beta estradiol
Jijana, Abongile Nwabisa (University of the Western Cape, 2016)Estrogens play an extraordinary role in the endocrine system regulation through the stimulation and regulation of endocrine pathways. 17β-estradiol is one of the final metabolites in estrogen regulation by hydroxylase ...
