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. ...
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, ...
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 ...
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 ...
Nanoparticles-infused lithium manganese phosphate coated with magnesium-gold composite thin film - a possible novel material for lithium ion battery olivine cathode.
(University of the Western Cape, 2014)
Architecturally enhanced electrode materials for lithium ion batteries (LIB) with permeable morphologies have received broad research interests over the past years for their promising properties. However, literature based ...
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 ...
Liquid-liquid interface ion-transfer amperometric sensors for tenofovir as a model nucleoside/nucleotide anti-retroviral drug
(University of the Western Cape, 2014)
Amperometric sensors for Tenofovir, a model nucleotide/ nucleoside reverse transcriptase inhibitor ARV drug, were studied based on the principle of ion-transfer electrochemistry at the membrane-stabilized oil/ water interface ...
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 ...
Cytochrome P450 2E1/Nickel-Poly(propylene imine) dendrimeric nanobiosensor for pyrazinamide - A first line TB Drug
(University of the Western Cape, 2015)
The tuberculosis (TB) disease to this day remains one of the world’s prominent killerdiseases. Pyrazinamide (PZA) is one of the most commonly prescribed anti- tuberculosis (anti-TB) drugs due to its ability to significantly ...
The design of ultrasensitive immunosensors based on a new multi-signal amplification gold nanoparticles-dotted 4-nitrophenylazo functionalised graphene sensing platform for the determination of deoxynivalenol
(University of Western Cape, 2014)
A highly dispersive gold nanoparticle-dotted 4-nitrophenylazo functionalised graphene
nanocomposite (AuNp/G/PhNO2) was successfully synthesised and applied in enhancing
sensing platform signals. Three label-free ...
