Summary for Patent: 7,960,169
Title:Biological indicator
Abstract: A biological indicator for monitoring the effectiveness of a sterilizing, disinfecting treatment or process. A compound or condition is disclosed which comprises a substrate containing functional groups residing on a surface thereof, said functional end groups being desirably free of silicon linking groups. The functional end groups are desirably in the form of a monolayer of a uniform distribution and of a selected quantity. Various types of microorganisms, such as spores, fungi, mycobacteria, vegetative bacteria, protozoa, and/or etiological agents are covalently bonded to the functional end groups through a zero-length crosslinking agent and thus form a uniform number and distribution of microorganisms and/or etiological agent indicators on a surface of the substrate. After being subjected to sterilization, disinfection, or other similar treatments or processes, along with various articles such as instruments, the indicator can be cultured in an appropriate medium to determine the effectiveness of the sterilization, disinfection, or other similar process.
