ABSTRACT:
A biological indicator for monitoring the effectiveness of a sterilizing, disinfecting, etc., compound or condition is disclosed which comprises a substrate having a surface layer containing functional groups thereon desirably free of silicone linking groups. The functional groups are desirably in the form of a monolayer of a uniformed distribution and of a selected quantity. Various types of microorganisms such as spores and/or etiological agents are covalently bonded to the surface layer functional groups through a crosslinking reagent and thus form a uniform number and distribution of the microorganisms and/or etiological agents. After being subjected to sterilization or other similar treatment, etc., along with various articles such as instruments, the indicator can be cultivated to determine the effectiveness of the sterilization, disinfection, etc. process.
