Microfluidic graphenised-paper electroanalytical devices (μGPED) for adsorptive cathodic stripping voltammetric detection of metal contaminants
(University of the Western Cape, 2017)
The need for clean, non-toxic drinking water supplies, free of pollutants and metal
contamination is vital in impoverished areas and the developing world alike. With this in mind,
the development of accurate, inexpensive, ...
Quantum dots-amplified electrochemical cytochrome P450 phenotype sensor for tamoxifen, a breast cancer drug
(University of the Western Cape, 2017)
Breast cancer is regarded as the most common cancer in South Africa and its rate of
occurrence is increasing. About one in every 31 South African women are at the risk of
developing breast cancer and early diagnosis and ...
Electrochemical poly(ProDOT) dendritic DNA aptamer biosensor for signalling interferon gamma (IFN-ɣ) TB biomarker
(University of the Western Cape, 2017)
Tuberculosis (TB) is an infectious disease that, despite all efforts devoted towards its
eradication, remains a threat to many countries including South Africa. Current diagnostic
assays do offer better performance than ...
The development of graphene oxide sheet- and polyanilino-immunosensor systems for lipoarabinomannan (LAM) tuberculosis biomarker
(University of the Western Cape, 2017)
Tuberculosis (TB) is an infectious disease with adverse effect on a global scale. The disease is one of the major causes of death in sub-Saharan Africa. Nearly 70% of TB-infected persons are co-infected by the human ...
Development of Schiff base electrochemical sensors for the evaluation of polycyclic aromatic hydrocarbons in aqueous medium
(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 ...
Electrochemical in-situ polymerization of graphene oxide/conducting star copolymer nanocomposite as supercapacitor electrode
(University of the Western Cape, 2017)
These days there are deep concerns over the environmental consequences of the rate of
consumption of energy from non-renewable sources because of the accelerated increase in greenhouse effect. There is, therefore, increasing ...
Functionalisation of polymer nanofibres and track-etched membrane removal of organic and and inorganic pollutants from water
(University of the Western Cape, 2017)
Organic and inorganic pollutants are two broad classes of pollutants in the
environment with their main sources from waste waters that are indiscriminately
dumped from chemical related industries. Among the organic ...
Development of capacitive deionisation electrodes: optimization of fabrication methods and composition
(University of the Western Cape, 2017)
The objective of this research was to optimize the fabrication methods for and compositions of
electrodes for the Membrane Capacitive Deionisation (MCDI) system. Two electrode
fabrication methods were developed, namely a ...
Hydrogel encapsulated biosensors for the detection of biologically significant vanadium and selenium
(University of the Western Cape, 2017)
Vanadium and selenium salts are toxic in large amounts, but trace amounts are
necessary for cellular function in many organisms. Exposure to high level of selenium
has been linked to delays in early childhood development ...
Phytochemical and biological studies on some South African plants used in traditional medicine for skin hyperpigmentation.
(University of the Western Cape, 2017)
The regulation of the Western beauty care products is currently inadequate and a huge concern to
consumers throughout the world, as most of the products manufactured by personal care industry
are made of synthetic additives, ...
