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 ...
Electrochemical and optical modulation of selenide and telluride ternary alloy quantum dots genosensors
(University of the Western Cape, 2012)
Electroanalytical and optical properties of nanoscale materials are very important for biosensing applications as well as for understanding the unique one-dimensional carrier transport mechanism. One-dimensional semiconductor ...
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 ...
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 ...

Electrochemical ochratoxin a immunosensors based on polyaniline nanocomposites templated with amine- and sulphate-functionalised polystyrene latex beads
(University of the Western Cape, 2010)
Polyaniline nanocomposites doped with poly(vinylsulphonate) (PV-SO3) and nanostructured polystyrene (PSNP) latex beads functionalized with amine (PSNP-NH2) and sulphate ((PSNP-OSO3) were prepared and characterised for use ...
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. ...
Electrochemical responses of novel preferentially oriented platinum (100) nanoalloys for ammonia and hydrazine catalysis
(University of the Western Cape, 2013)
Ammonia has attracted attention as a possible fuel for direct fuel cells since it is easy to handle under low pressure, costs only slightly higher than methanol and can easily be cracked down into hydrogen and nitrogen. ...
Development of Impedimetric Immunosensor for Fumonisin on Polyanilino-Carbon Nanotubes Doped with Palladium Telluride Nanocrystals
(University of the Western Cape, 2013)
Immunosensors are affinity ligand-based biosensor solid-state devices in which the immunochemical reaction is coupled to a transducer. The specificity of the molecular recognition of antigens by antibodies to form a stable ...
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 ...
