AtNOGC1 protein bioelectrode for the determination of stress signalling molecules - Nitric Oxide (NO), Carbon Monoxide (CO) and Calcium ion (Ca2+)
(University of the Western Cape, 2018)
It has been estimated that the world population will reach about 10 billion by the year 2050 and in order to accommodate the increased demand of food, the world agricultural production needs to rise by 70 % in the year ...
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 ...
Polyamic acid-graphene oxide nanocomposite for electrochemical screening of antibiotic residues in water
(University of the Western Cape, 2015)
Pollution of water sources, aquifers and wetland systems caused by industry, agriculture, and municipally treated wastewater is a worldwide problem that contributes to the scarcity of clean and potable water. Rivers, ...
Protein phosphatase biosensor for the detection of cyanotoxins associated with algal bloom
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 ...
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. ...
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 ...
