The body comprises a first layer attached to a second layer, forming at least one isolatable microchamber and at least one primary passageway that provides fluidic communication between ambience and the at least one microchamber. The microchamber has an isolated volume of about 0.5 microliters to about 9.5 microliters. The plurality of test microorganisms and the oxygen-modulated first fluorescent sensor are disposed in the microchamber. A method of using the device to determine the effectiveness of a sterilization process is also provided.

摘要： A biological sterilization indicator (BI) and a method of using same for assaying the lethality of a sterilization process. The BI can include a housing, which can include a first portion, and a second portion, which can be movable with respect to the first portion between a first and second position. The BI can further include a frangible container comprising a liquid. The BI can further include a spore reservoir and a projection positioned in the housing. The projection can be configured to fracture the container when the second portion of the housing is moved from the first position to the second position. The method can include maintaining a minimal cross-sectional area of space around the container when the second portion of the housing is in the first position, and fracturing the container in response to moving the second portion between the first and second positions.

摘要： A biological sterilization indicator, system, and methods of determining the effectiveness of a sterilization process. The biological sterilization indicator can include a locus of spores, a reservoir containing a liquid, and a sterilant path positioned to provide fluid communication between ambience and the locus of spores. The reservoir can have a closed state in which the reservoir is not in fluid communication with the locus of spores and an open state in which the reservoir is in fluid communication with the locus of spores. The biological sterilization indicator system can include the biological sterilization indicator and a detection device adapted to be coupled to the biological sterilization indicator. In some embodiments, the method can include assaying the spores for a detectable change in a characteristic, and detecting substantially all of the detectable change.
