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.
