Effect of TiO2 nanoparticles on the antibacterial and physical properties of polyethylene-based film

Stable poly(St-co-BA) nanoemulsion polymerization for high performance antibacterial coatings in the presence of dioctyldimethylammonium chloride

“…After cultivation at 37°C 90% humidity for 24 h in a constant temperature and humidity incubator (Huangshi City Hengfeng Medical Instrument Co., Ltd, Huangshi, China), these testing samples were washed by 20 mL sterilized 0.9% saline water and then were diluted and counted, respectively. All of these tests were repeated at least four times [43].…”

Nanopartículas de óxido de zinco sintetizadas pelo método poliol: caracterização e avaliação da atividade antibacteriana

“…No que concerne o desenvolvimento de nanoestruturas com propriedades antibacterianas para aplicações diversas, é possível encontrar na literatura trabalhos envolvendo o uso de nanopartículas de prata [2], cobre [3], óxido de zinco [4], dióxido de titânio [5] e dióxido de estanho [6]. O uso de nanopartículas metálicas para aplicação como agentes antibacterianos aparece como uma importante alternativa aos tradicionais organoclorados e aos derivados de arsênio, usualmente empregados para esta finalidade.…”

Antibacterial efficiencies of TiO2 nanostructured layers prepared in organic viscous electrolytes

“…TiO 2 was used for antibacterial applications having incorporated components (such as Ag or Zn) with biocidal activity [16,17]. Also, ultraviolet (UV) light on titanium dioxide can be used to generate oxidative effect by formation of reactive oxygen species or highly reactive hydroxyl radicals, which are strong enough for lysis of microbes [16,18]. Other studies show that addition of Cu-doped TiO 2 nanoparticles, significantly reduced the Mycobacterium smegmatis growth rate, and the antibacterial effect increased with the Cu content in nanoparticles [19].…”
