Heavy and precious metal toxicity evaluation using a horseradish peroxidase immobilised biosensor
(University of the Western Cape, 2012)
Environmental pollution is always the hottest topic in public conversation and one of the most concerned aspects of human health. The thin film sputtered microelectrode devices have been developed to improve the quality ...
Graphenated polyaniline nanocomposite for the determination of polyaromatic hydrocarbons (pahs) in water
(2013)
The thesis presents a simple, sensitive, low cost and a novel graphenated polyaniline doped tungsten trioxide nanocomposite, as an electrochemical sensor for the detection and quantitative and determination of PAHs, which ...
Frequency and voltage-modulated electrochemical aflatoxin b1immunosensor systems prepared on electroactive organic polymer platforms
(2008)
In the presented work, immunosensors for detection of Aflatoxin B1 based on
different immobilization platforms were studied. Synthesis of an electroactive
hydrogel was also carried out. Aflatoxins are a group of mycotoxins ...

Mercaptobenzothiazole-on-Gold Biosensor Systems for Organophosphate and Carbamate Pesticide Compounds
(University of the Western Cape, 2007)
This study firstly reports the development, characterisation, and application of thick-film acetylcholinesterase (AChE) biosensors based on a gold electrode modified with a mercaptobenzothiazole (MBT) self-assembled monolayer ...
Development of polyaniline nanotube electrocatalysts and sesor devices for phenolic-pollutants
(University of the Western Cape, 2007)
As a source of life, water is one of the most precious commodities for all living organisms. Water resources are reported to be declining in numbers or the amount of water present and the existing onses are being polluted ...
Electrochemical ochratoxin a immunosensors based on polyaniline nanocomposites templated with amine- and sulphate-functionalised polystyrene latex beads
(University of the Western Cape, 2010)
Polyaniline nanocomposites doped with poly(vinylsulphonate) (PV-SO3) and nanostructured polystyrene (PSNP) latex beads functionalized with amine (PSNP-NH2) and sulphate ((PSNP-OSO3) were prepared and characterised for use ...
Electrochemical characterization of nanostructured SnO2 and TiO2 for potential application as dielectric materials in sulfonated-polyaniline based supercapacitors
(University of the Western Cape, 2010)
In this research project, nanostructured composites based on Tin dioxide (SnO2) and Titanium dioxide (TiO2) with poly-4-styrene sulfonic acid (PSSA) doped polyaniline (PANI) conducting polymer has been investigated based ...
The development of l-phenylalanine biosensor using boron-doped diamond (bdd) electrode modified with poly aniline-polyvinyl sulphonate composite film
(University of the Western Cape, 2010)
The aim of this project was to develop a biosensor on a modified boron-doped diamond (BDD)
platform in order to determine L-phenylalanine (L-Phe) levels in the aqueous media and real
samples. A BDD electrode modified ...
Electro chemiluminescence and organic electronics of derivatised poly(aniline sulphonic acid) light-emitting diodes
(University of the Western Cape, 2011)
Electrochemiluminescence (EeL) is applied for industrial applications that have considerable potential, such as clinical diagnostic, analytical chemistry, and light-emitting devices, due to selectivity, sensitivity for ...
