The toxicity of silver nanoparticles
(University of the Western Cape, 2012)
Unavailability and contamination of available water resources are major factors contributing to adverse health conditions worldwide. AgNPs present a potential strategy for water purification; however, their ability to ...
Zeolite encapsulated metal complexes as heterogeneous catalysts for oxidation reactions
(University of the Western Cape, 2012)
This study describes the synthesis and characterisation of Cu(II) and V(IV) complexes of tri- and quadridentate ligands L1 and L2 formed by condensation of ethylenediamine with acetylacetonate in 1:1 and 1:2 molar ratio, ...
Synthesis and characterization of rhenium (vii) and rhuthenium (ii) dendritic catalysts: oxidative cleavage and epoxidation of alkenes
(2012)
Herein we report the successful synthesis of a class of stable and flexible Schiff-base chelators capable of coordinating both ruthenium (II) and rhenium (VII) and which would be catalytically active for oxo-transfer ...
Electrochemical characterization of platinum based catalysts for fuel cell applications
(University of the Western Cape, 2012)
Fuel cells convert chemical energy from a fuel into electricity through chemical reaction with oxygen. This possesses some challenges like slow oxygen reduction reaction (ORR),
overpotential, and methanol fuel cross over ...
Optimisation of a microfluidic device for the pre-concentration and size separation of cell free foetal DNA from maternal plasma by capillary electrophoresis
(University of the Western Cape, 2012)
The discovery of cell free foetal DNA (cffDNA) in 1997 allows for the combination of accuracy as well as non-invasiveness for prenatal diagnosis. This non-invasive genetic test requires only a maternal blood sample from ...
Electrodeposition of multi-valent metal oxides at 1-methyl-3-octylimidazolium bis(trifluoromethylsulfonyl) imide ionic liquid - carbon paste electrode
(University of the Western Cape, 2012)
A study on carbon paste electrode (CPE) materials containing 1-methyl-3-octylimidazolium bis (trifluoromethylsulfonyl) imide [MOIM[Tƒ2N] – a hydrophobic room temperature ionic liquid (IL) - is reported. CPEs with (a) the ...
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 ...

Novel 3-mercaptopropionic acid capped iridium selenide quantum dots modified electrochemical immunosensor for the detection of fish toxin, nodularin
(University of the Western Cape, 2012)
A novel 3-mercaptopropionic acid capped iridium selenide quantum dots based label free impedimetric immunosensor was successfully constructed. The 3-mercaptopropionic acid capped iridium selenide quantum dots synthesized ...
Heavy and precious metal toxicity evaluation using a horseradish peroxidase immobilised biosensor
(University of the Western Cape, 2012)
Environmental pollution is always the hottest topic in public conversation and one of the most concerned aspects of human health. The thin film sputtered microelectrode devices have been developed to improve the quality ...
