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, ...
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 ...
Optical and microarray silver-gold based sensors for the detection of e.coli 0157:h7 in seawater
(University of the Western Cape, 2021)
Recently researchers reported that nanoparticles functionalised through chemical methods possess risks to the environment and to the human health since they use hazardous chemicals and produce toxic waste. The increasing ...
Frequency and voltage-modulated electrochemical aflatoxin b1immunosensor systems prepared on electroactive organic polymer platforms
(2008)
In the presented work, immunosensors for detection of Aflatoxin B1 based on
different immobilization platforms were studied. Synthesis of an electroactive
hydrogel was also carried out. Aflatoxins are a group of mycotoxins ...

Nanocomposite immunosensor for anti-transglutaminase antibody
(University of the Western Cape, 2009)
Coeliac disease (CD) is a gluten intolerance condition that results in the flattening of the villi, which line the bowel. It is the most common cause of malabsorption of food nutrients. This inability to absorb sufficient ...
Electrochemical actuation potential of diaminophenazine linked pyrrole derivatives
(2013)
A novel monomer (Phenazine-2,3-diimino(pyrrole-2-yl)–PDP) derived from the condensation reaction between 2,3-diaminophenazine and a pyrrole derivative has
been synthesized as a hinge molecule in the design of a zig-zag ...
Phytochemical synthesis and antimicrobial application of gold nanoparticles from extract of Artemisia annua
(University of the Western Cape, 2023)
Metallic nanoparticles synthesized using chemical methods and physical methods are considered toxic to the environment due to the use of toxic solvents. The biological synthesis methods such as the use of plant extracts ...
Impedimetric and electrode kinetic dynamics of DNA aptamer nanobiosensors for estrogeneous endocrine disruptors
(University of the Western Cape, 2011)
In this work, DNA aptamer biosensor systems were developed for the detection of l7p-estradiol - an estrogeneous endocrine disrupting chemical (EDC). Endocrine disrupting chemicals are group of compounds that impact negatively ...
