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： Method for detecting an analyte of interest in a sample. The method can include providing a container comprising a microstructured surface, and centrifuging the container toward the microstructured surface to form a sediment and a supernatant of the sample. Following centrifugation, the container can be inverted to decant at least a portion of the supernatant of the sample from the second portion, such that a concentrate (e.g., comprising the sediment) of the sample is retained in the microstructured surface. The concentrate can then be interrogated in the microstructured surface for the analyte of interest. In some embodiments, at least a portion of the second portion can be substantially transparent, such that the concentrate can be interrogated from the outside of the container, without requiring that the container be opened prior to interrogation.
