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 ...
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 ...
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 ...
Complexation and Bioavailability of Dissolved Mercury Evaluation by Hplc and a Novel Au-Hydrogel Analytical Sensor Protocol.
(University of the Western Cape, 2017)
Anthropogenic sources as well as natural contributions (e.g. volcanic activity and evaporation
from the oceans) have increased mercury levels in the environment. Mercury deposits mainly in
sediments, and it finally ends ...
Optical and electronic properties of methylammonium lead halide perovskite solar cells
(University of the Western Cape, 2017)
Organic-inorganic hybrid perovskite solar cells have emerged as promising materials for next-generation
photovoltaics with certified efficiency of 22.1%. Despite rapid developments, achieving precise control
over the ...
Next generation bulk Heterojunction organic Photovoltaic and light emitting diode sytems of Novel Polycyclic Aromatic Hydrocarbon, Polyfluorenes and Polythiophenes
(University of the Western Cape, 2017)
In these times of diminishing reserve of fossil fuel, the development of novel - green or
renewable? technologies to meet the increasing worldwide demand for energy is of great
importance. The sun is the largest carbon ...
