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 ...
Vertically aligned silicon nanowires synthesised by metal assisted chemical etching for photovoltaic applications
(University of the Western Cape, 2015)
One-dimensional silicon nanowires (SiNWs) are promising building blocks for solar cells as they provide a controlled, vectorial transport route for photo-generated charge carriers in the device as well as providing ...
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 ...
The effects of nanomaterials, in the presence and absence of serum proteins, on testicular cell metabolic processes and steroidogenesis
(University of the Western Cape, 2014)
The aim of this study is to be the first to ascertain the effects of silver nanoparticles on testosterone production. The Ag NPs used for this study have the following characteristics; purity ≥ 99.5%; 66.7 % of particles ...
Synthesis of silver nanoparticles and investigating their antimicrobial effects
(University of the Western Cape, 2015)
Water is essential for life, yet access to safe drinking water is still a major concern worldwide due to waterborne diseases. The current study proposes silver nanoparticles (AgNPs) as an antibacterial agent. Silver ...
Potamanautes warreni biomarker assays to monitor silver nanomaterial contaminants in aquatic environments
