The preparation of an immunosensor for the detection of microcystins and nodularins by immobilisation of a labelled antibody onto a polymer modified electrode
(University of the Western Cape, 2011)South African dams and reservoirs are increasingly showing the propensity to support sustained populations of Cyanobacteria (blue green algae). These photosynthetic bacteria occur throughout the world and can rapidly form ... -
Protein phosphatase biosensor for the detection of cyanotoxins associated with algal bloom
(2013)The toxicity of microcystin is associated with the inhibition of serine/threonine protein phosphatases 1 and 2A, which can lead to hepatocyte necrosis and haemorrhage. Analysis of microcystin is most commonly carried out ... -
Spectroelectrochemical determination of the antioxidant properties of carpobrotus mellei and carpobrotus quadrifidus natural products
(2009)South African Carpobrotus species have been found to contain hydrolysable tannins,various flavonoids e.g. rutin and hyperoside, phytosterols and aromatic acids which have a diverse range of pharmacological properties ... -
Synthesis and electrochemical characterisation of conducting polyaniline-fly ash matrix composites
(2005)The aim of this study was to produce useful composite materials from fly ash, a major waste product of coal combustion from power plants. Polyaniline-fly ash (PANI-FA) composites were prepared by in situ polymerisation of ... -
Synthesis and electrochemistry of novel conducting dendrimeric star copolymers on poly(propylene imine) dendrimer
(University of the Western Cape, 2011)One of the most powerful aspects of conducting polymers is their ability to be nanostructured through innovative, synthetically manipulated, transformations, such as to tailor-make the polymers for specialized applications. ... -
Synthesis of sulphonated and transition metal oxide doped polymeric nanocomposites for application in design of supercapacitors
(University of the Western Cape, 2011)To meet a fast-growing market demand for next generation portable electronic devices with higher performance and increased device functionalities, efficient electrical energy devices with substantially higher energy, power ... -
Synthesis, electrodynamics and biosensor applications of novel sulphonated polyaniline nanocomposites
(University of the Western Cape, 2007)The overall aim of this thesis was to prepare nanostructured more processable heteronuclear sulphonated polyanyline nanocomposites with electroconductive properties suitable for applications in biosensors. The sulphonated ... -
Synthetic strategies for denatured cytochrome-c analogues towards analytical reporting of NOx species
(University of the Western Cape, 2019)Nitric oxide (NO) plays a key role as biological messenger in the biological system, however detection and quantification thereof has always posed significant problems. NOx is a principal constituent of air pollutants. ... -
Towards rapid electrochemical test system of polyanilino-laccase-on-gold enzyme nanobiosensor for water estrogens
(2013)Current water treatment technologies do not remove many endocrine disruptor compounds (EDCs) such as 17α-ethynylestradiol (EE2) in its entirety, and the amount of these pollutants that continues to enter the aquatic ...
