Development of Metal Nanoparticle-Doped Polyanilino-Graphene Oxide High Performance Supercapacitor Cells
(University of the Western Cape, 2018)Supercapacitors, also known as ultracapacitors or electrochemical capacitors, are considered one of the most important subjects concerning electricity or energy storage which has proven to be problematic for South Africa. ... -
Green synthesis of silver nanoparticles using honey from the meliponinae stingless bee species and antibacterial studies.
(University of the Western Cape, 2023)Green synthesis of silver nanoparticles (AgNPs) is an environmentally friendly approach for preparing nanoparticles using biological sources as the reducing agent. Apart from using plant extracts, honey, that is used in ... -
Identification, separation and quantification of persistent organic pollutants using capillary electrophoresis
(University of the Western Cape, 2022)Water quality deterioration and scarcity can be attributed to natural causes and anthropogenic activities which include climate change and an incessant industrialisation, yet with lack of functional and reliable wastewater ... -
Nanoparticulate of silver-modified poly (8-anilino-1-naphthalene sulphonic acid) nanobiosensor systems for the determination of Tuberculosis treatment drugs
(University of the Western Cape, 2011)This study firstly reports the development and characterization of PVP-AgNPs, PANSA and PVPAgNPs/ PANSA nanocomposite on gold. AFM and TEM analyses revealed highly electroactive nanocomposites whose morphogy and properties ... -
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 ... -
Photocatalytic degradation of organic pollutants using Ag-Fe₃O₄/SiO₂/TiO₂ nanocomposite
(University of the Western Cape, 2015)The global lack of clean water for human sanitation and other purposes has become an emerging dilemma for human beings. The presence of organic pollutants in wastewater produced by textile industries, leather manufacturing ... -
Spectroelectrochemical graphene-silver/zinc oxide nanoparticulate phenotype biosensors for ethambutol and pyrazinamide
(University of the Western Cape, 2019)Tuberculosis (TB), a deadly disease second to HIV/AIDS, is a global health problem. Diagnosis of active tuberculosis is tedious and requires expensive procedures since there is no recognizable method for sole detection ... -
The toxicity of silver nanoparticles
(University of the Western Cape, 2012)Unavailability and contamination of available water resources are major factors contributing to adverse health conditions worldwide. AgNPs present a potential strategy for water purification; however, their ability to ...
