METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR DETERMINING PHYSICAL PROPERTIES OF A SPECIMEN IN A PORTABLE POINT OF CARE DIAGNOSTIC DEVICE

摘要

Methods, systems, and computer readable media for determining physical properties of a specimen in a portable point of care device are disclosed. According to one aspect, a method includes placing a specimen onto an active surface that includes a plurality of microposts extending outwards from a substrate, wherein each micropost includes a proximal end attached to the substrate and a distal end opposite the proximal end and generating an actuation force in proximity to the micropost array that compels at least some of the microposts to exhibit motion. The method further includes detecting light that is emitted by an illumination source and interacts with the active surface while the at least some microposts exhibit motion in response to the actuation force, measuring data that represents the detected light interacting with the active surface, and determining at least one physical property of the specimen based on the measured data.
