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 ...
Palladium telluride quantum dots biosensor for the determination of indinavir drug
(2013)
Indinavir is a potent and well tolerated protease inhibitor drug used as a component of the highly active antiretroviral therapy (HAART) of HIV/AIDS, which results in pharmacokinetics that may be favourable or adverse. ...
The Isolation and Electrochemical Studies of Flavanoids from Galenia africana and Elytropapus rhinocerotis from the North Western Cape
(University of the Western Cape, 2010)
In this study two medicinal plant species, namely Galenia africana and Elytropapus rhinocerotis, the former belonging to the family Aizoceae and the latter belonging to the family Asteraceae, have been investigated and ...
Graphenated polyaniline nanocomposite for the determination of polyaromatic hydrocarbons (pahs) in water
(2013)
The thesis presents a simple, sensitive, low cost and a novel graphenated polyaniline doped tungsten trioxide nanocomposite, as an electrochemical sensor for the detection and quantitative and determination of PAHs, which ...
Towards rapid electrochemical test system of polyanilino-laccase-on-gold enzyme nanobiosensor for water estrogens
(2013)
Current water treatment technologies do not remove many endocrine disruptor compounds (EDCs) such as 17α-ethynylestradiol (EE2) in its entirety, and the amount of these pollutants that continues to enter the aquatic ...
