The antibacterial properties of self-cleaning coatings are based on bactericide nanoparticles (NPs). Ecotoxicity of these NPs have been assessed mostly in suspension, using standard bioassays. Here a protocol is proposed to test actual coating samples, using the Vibrio fischeri bioluminescence inhibition bioassay. The protocol was designed to test bactericide properties of specially coated PVC floors being used in hospital environments under quasinatural conditions, such as prolonged exposure or room temperature. To take into consideration that the light output of the bacteria under prolonged exposure naturally changes, a correction factor is proposed.
自清洁涂层的抗菌性能基于杀菌剂纳米颗粒 (NPs)。这些 NPs 的生态毒性主要在悬浮液中使用标准生物测定法进行评估。本研究提出了一种使用发光菌生物发光抑制生物测定法测试实际涂层样品的方案。该方案旨在测试医院环境中特殊涂层 PVC 地板的杀菌性能,这些地板在准自然条件下使用,例如长时间暴露或室温。为了考虑到长时间暴露下细菌的发光输出自然变化,提出了一个校正因子。
