Cytochrome P450 2E1/Nickel-Poly(propylene imine) dendrimeric nanobiosensor for pyrazinamide - A first line TB Drug
(University of the Western Cape, 2015)The tuberculosis (TB) disease to this day remains one of the world’s prominent killerdiseases. Pyrazinamide (PZA) is one of the most commonly prescribed anti- tuberculosis (anti-TB) drugs due to its ability to significantly ... -
Detection of selective tyrosinase inhibitors from some South African plant extracts of lamiaceae family
(University of the Western Cape, 2016)Various dermatological disorders, such as formation of black pigmented patches on the surface of the skin arise from the over-activity of tyrosinase enzyme's degenerative action. This enzyme is further implicated in the ... -
Determination of paracetamol at the electrochemically reduced graphene oxide-metal nanocomposite modified pencil graphite (ERGO-MC-PGE) electrode using adsorptive stripping differential pulse voltammetry
(University of Western Cape, 2020)This project focuses on the development of simple, highly sensitive, accurate, and low cost electrochemical sensors based on the modification of pencil graphite electrodes by the electrochemical reduction of graphene ... -
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 ... -
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 ... -
Electrochemical immunosensor based on cyclodextrin supramolecular interactions for the detection of human chorionic gonadotropin
(University of the Western Cape, 2012)Glucose oxidase (GOx) and horseradish peroxidase (HRP) are important enzymes for the development of amperometric enzyme linked immunosensors. The selectivity of each enzyme towards its analyte deepens its importance in ... -

The Isolation and Electrochemical Studies of Flavanoids from Galenia africana and Elytropapus rhinocerotis from the North Western Cape
(University of the Western Cape, 2010)In this study two medicinal plant species, namely Galenia africana and Elytropapus rhinocerotis, the former belonging to the family Aizoceae and the latter belonging to the family Asteraceae, have been investigated and ... -
Liquid-liquid interface ion-transfer amperometric sensors for tenofovir as a model nucleoside/nucleotide anti-retroviral drug
(University of the Western Cape, 2014)Amperometric sensors for Tenofovir, a model nucleotide/ nucleoside reverse transcriptase inhibitor ARV drug, were studied based on the principle of ion-transfer electrochemistry at the membrane-stabilized oil/ water interface ... -
Nanocomposite immunosensor for anti-transglutaminase antibody
(University of the Western Cape, 2009)Coeliac disease (CD) is a gluten intolerance condition that results in the flattening of the villi, which line the bowel. It is the most common cause of malabsorption of food nutrients. This inability to absorb sufficient ... -
