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.
本发明公开了一种用于监测灭菌、消毒等化合物或条件有效性的生物指示剂,它包括一个基底,该基底具有一个表面层,该表面层上含有官能团,最好不含硅酮连接基团。官能团最好呈单层形式,分布均匀,数量可选。各种微生物(如孢子和/或病原体)通过交联试剂与表面层官能团共价键合,从而形成数量和分布均匀的微生物和/或病原体。在与器械等各种物品一起进行灭菌或其他类似处理等之后,可对指示剂进行培养,以确定灭菌、消毒等过程的有效性。
