Toxic effects against bacteria of silver nanocolloids and silver nanotubes in the presence of hydra cells

摘要: Silver nanomaterials are widely used in commercial products, because the released silver be worried about ecotoxicity of freshwater organisms environment. We have focused on reducing nanotoxicity using environmentally-friendly biological process by hydra cells. The has a strong regenerative capacity toxic chemicals, excellent adhesion and aggregation cells through self-organization during regeneration stages. test examined two types nanocolloids (Ag NCs) nanotubes NTs) at concentrations 5, 10, 50, 100 mg/L, respectively. In addition, we compared to antimicrobial effects against E. coli (Gram-negative) S. aureus (Gram-positive) bacteria Ag NCs, NTs NCs including aim this study is not only investigate nanotoxic mixed but also compare between NTs. Our results suggest that can reduced both bacteria. Because, cell were coiled around which may inhibited aggregations blocked ions. Furthermore, shapes different according species sensitivity
