Abstract
Systems and methods for concentrating a sample and detecting an analyte of interest. The system can include a sample detection container that can include a microcavity. The microcavity can include a top opening, a base, and a longitudinal axis. The container can further include a wall that extends to the microcavity, wherein at least a portion of the wall located adjacent the top opening of the microcavity has a slope that is oriented at an effective angle α with respect to the longitudinal axis of the microcavity. The effective angle α can be greater than 45 degrees and less than 90 degrees, and at least the portion of the wall located adjacent the top opening of the microcavity that is oriented at the effective angle α can have a length of at least 5 times a transverse dimension of the microcavity.
