Synthesis of peptide-loaded chitosan nanoparticles for the treatment of sexually transmitted infections (STI’s)
(University of Western Cape, 2019)
Peptides are among the main drugs which attract much attention because of their great potential
in treating sexually transmitted diseases and other chronic diseases. There has been a major
challenge of delivering these ...
An investigation of the natural products composition of Porphyra capensis (a red seaweed)
(University of the Western Cape, 2017)
Plants have been widely used in traditional medicine for a number of ailments, among which may
be included infectious diseases such as colds, influenza, chicken pox, TB, etc. as well as lifestyle
diseases such as diabetes ...
Electrochemical deposition of Graphene Oxide- metal nano-composite on Pencil-Graphite Electrode for the high sensitivity detection of Bisphenol A by Adsorptive Stripping Differential Pulse Voltammetry
(University of the Western Cape, 2018)
Electrochemical platforms were developed based on pencil graphite electrodes (PGEs) modified
electrochemically with reduced graphene oxide metal nanoparticles (ERGO–metalNPs) composite
and used for the high-sensitivity ...
P- and e- type Semiconductor layers optimization for efficient perovskite photovoltaics
(University of Western Cape, 2019)
Perovskite solar cells have attracted a tremendous amount of research interest in the scientific community recently, owing to their remarkable performance reaching up to 22% power conversion efficiency (PCE) in merely 6 ...
The development of l-phenylalanine biosensor using boron-doped diamond (bdd) electrode modified with poly aniline-polyvinyl sulphonate composite film
(University of the Western Cape, 2010)
The aim of this project was to develop a biosensor on a modified boron-doped diamond (BDD)
platform in order to determine L-phenylalanine (L-Phe) levels in the aqueous media and real
samples. A BDD electrode modified ...
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 ...
Electro chemiluminescence and organic electronics of derivatised poly(aniline sulphonic acid) light-emitting diodes
(University of the Western Cape, 2011)
Electrochemiluminescence (EeL) is applied for industrial applications that have considerable potential, such as clinical diagnostic, analytical chemistry, and light-emitting devices, due to selectivity, sensitivity for ...
