摘要: The present invention provides method of detecting a predetermined biological activity. The method includes using an aqueous mixture comprising a first indicator reagent with a first absorption spectrum and a second indicator reagent. The second indicator reagent is converted by the predetermined biological activity to a second biological derivative with a second emission spectrum. The first absorbance spectrum includes detectable absorbance in at least a portion of wavelengths present in the second emission spectrum. The first indicator reagent is received and concentrated from an aqueous liquid by a substrate, facilitating the detection of the second biological derivative.

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.

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.
