• Antibacterial activity of ZnO nanoparticle suspensions on a broad spectrum of microorganisms. (2008, methodology): “…formulations can be used as effective bactericidal materials (Tiller et al., 2001; Lin et al., 2002; Stoimenov et al., 2002; Kuhn et al., 2003; Sawai, 2003; Sunada et al., 2003; Sondi & Salopak-Sondi, 2004; Lewis & Klibanov, 2005; Rosi & Mirkin, 2005; Ma et al., 2006; Thill et al., 2006).”
• Nanomaterials in the environment: Behavior, fate, bioavailability, and effects (2008, background): “Cerium dioxide NPs may themselves be transformed after contact with living cells, oxidize membrane components involved in the electron transport chain, and cause cytotoxicity [118].”
• Occurrence, behavior and effects of nanoparticles in the environment. (2007, background): “coli, but the microscopic methods were not sensitive enough to discern whether internalization had taken place (Thill et al., 2006).”
• Bacterial toxicity comparison between nano- and micro-scaled oxide particles. (2009, background): “NPs, which are in the range of internal cell organs, may not only be used in manipulating or sensing biological systems (Jaiswal and Simon, 2004), but have also raised concerns about their possible harmful interactions in the environment (Nel et al., 2006; Thill et al., 2006).”
• Antibacterial activities of zinc oxide nanoparticles against Escherichia coli O157:H7 (2009, background): “Recent studies have shown that some NP made of metal oxides, such as ZnO NP, have selective toxicity to bacteria but exhibit minimal effect on human cells (Brayner et al. 2006; Thill et al. 2006; Reddy et al. 2007; Zhang et al. 2007).”
• The ecotoxicology and chemistry of manufactured nanoparticles (2008, background): “2006), and it is proposed that NPs with a positive charge such as cerium oxide could bind the Gram negative cell membrane by electrostatic attraction (Thill et al. 2006).”
