摘要： According to an embodiment, a sample collection system includes a sample collection device and an eluent delivery element. The sample collection devices includes a housing including an airflow path extending from a proximal end including an air inlet to a distal end; a piercing element arranged within the airflow path; and a sample collector including porous sample collection media arranged to occlude the airflow path. The eluent delivery element includes a reservoir containing an eluent; and a membrane disposed at a coupling end of the reservoir and sealing the reservoir, the coupling end being constructed to couple with the proximal end of the airflow path such that the piercing element pierces the membrane.

摘要： A light control film includes opposing substantially planar substantially parallel first and second major surfaces spaced apart along a thickness direction of the light control film by less than about 500 microns; and a plurality of substantially parallel optically transparent polymeric columns disposed in, and substantially surrounded by, a light absorbing polymeric material. Each of the polymeric columns has a first column end at the first major surface and an opposite second column end at the second major surface and has an aspect ratio of greater than about 3, such that the first column ends of at least one pair of adjacent polymeric columns include substantially parallel substantially straight sides facing, and substantially coextensive with, each other.

摘要： A sample collection system includes a housing comprising a first part and a second part, the first and second parts being movable relative to one another; porous sample collection media disposed along an airflow path in the first part; and an assay disposed on the second part and constructed to receive a sample captured by the porous sample collection media. The first and second parts may be slidably movable relative to one another. The first and second parts may be rotatably movable relative to one another. Moving the first and second parts relative to one another aligns the porous sample collection media with at least a portion of the assay. The assay may be a lateral flow assay or a vertical flow assay. The media is constructed to collect a sample from exhalation airflow. A collected sample may be eluted from the media onto the assay using a liquid.
