Evidence of free radical and antioxidant activity in Spirodela exposed to metallic and metal oxide nanoparticles: potential for protein and lipid damage

Author: Thwala, Melusi ; Musee, N ; Wepener, V ; Nota, N Date: Apr 2012 The toxicity of engineered nanoparticles towards macro algae and higher aquatic plants has not been well studied. This knowledge gap challenges the development of nano risk assessment towards water ecosystems. In this study, we investigated ... Read more
Exposure assessment of metal-based nanoparticles in aquatic environments: interactive influence of water chemistry and nanopaticle characteristics

Author: Thwala, Melusi ; Radebe, N ; Tancu, Y ; Musee, N Date: Sep 2014 Transformation and bioavailability information of engineered nanoparticles (ENPs) in environmental systems impedes assessment of their potential risks to aquatic environments. In aqueous environments ENPs undergo numerous transformation ... Read more
The oxidative toxicity of Ag and ZnO nanoparticles towards the aquatic plant Spirodela punctuta and the role of testing media parameters

Author: Thwala, Melusi ; Musee, N ; Sikhwivhilu, L ; Wepener, V Date: Sep 2013 The toxicity effects of silver (nAg) and zinc oxide (nZnO) engineered nanoparticles (ENPs) on the duckweed Spirodela punctuta were studied to investigate the potential risks posed by these ENPs towards higher aquatic plants. The influence of ... Read more
Potential susceptibility inhibitory effect of Ag and ZnO engineered nanoparticles on bacterial strains: effect of pH and temperature

Author: Mboyi, A ; Musee, N ; Zvimba, JN ; Momba, MNB Date: Aug 2013 The economic and social benefits of metallic silver (n-Ag) and zinc oxide (n-ZnO) engineered nanoparticles (ENPs) applications in medical, technological, environmental remediation, consumer products, among other have widely been demonstrated. ...
