Abstract: A sample acquisition device includes a body comprising a plurality of sample acquisition regions defined by at least a first wall and a second wall oriented nonparallel to the first wall. In some embodiments, the body defines a plurality of apertures that define a plurality of sample acquisition regions. In other embodiments, the walls extend from the body, and the sample acquisition regions are defined between the walls. The sample acquisition regions may be configured in some embodiments such that a user may acquire a sample by rotating the body in a first direction relative to a sample source and may release the sample by rotating the body in a second direction that is substantially opposite to the first direction. When rotated in the first direction, at least one of the first or second walls defines a surface that is inclined into a sample acquisition region.

Abstract: The invention relates to methods of capturing bacterial whole cells that includes the use of one or more antibodies having antigenic specificities for one or more distinct analytes characteristic of the specific bacterium, followed by analyzing the target whole cells using a direct or indirect ATP assay.

Abstract: A sample acquisition device includes a capillary array configured to draw in a sample and retain the sample by capillary action. The capillary array may be coupled to an elongated member, such as a stem or a hollow tube, which defines a longitudinal axis extending in a first direction. In some embodiments, the capillary array defines a major sample acquisition surface that extends in a second direction different than the first direction. A ratio of the major sample acquisition surface area to maximum volume retained by the capillary array may be selected to minimize physical binding between the capillary array and sample. In some embodiments, the device may include a feedback mechanism to indicate the relative pressure applied to a sample source with the sample acquisition device. In addition, in some embodiments, the sample acquisition device may include a suction source to help draw the sample into the capillary array.
