Abstract: An article and method are provided for assessing the efficacy of a sterilization process. The article comprises an outer container having an interior volume; a dry source of measurable biological activity disposed in the interior volume; and an effective amount of a dry agent for neutralizing a sterilant compound; wherein both the source of measurable biological activity and the agent are in vapor communication with an environment outside the outer container. The method comprises exposing the article to a first sterilant and, optionally, a second sterilant for a period of time and detecting the measurable biological activity.

Abstract: Spore carriers suitable for use in biological indicators are described. The spore carriers include a substrate such as polymeric film or non-woven web with a hydrophilic nanostructured layer bonded to it. Spores are bonded to the nanostructured layer. Nanostructured layers including nanoparticles, such as acid-sintered silica nanoparticles are described. Biological indicators including such spore carriers are also described.

Abstract: The disclosed sterilization monitoring device comprises a perfusion channel with a chemical indicating composition disposed in fluid communication with the perfusion channel. Exposure to a sterilant creates a laterally moving front across the chemical indicating composition in the perfusion channel.
