Abstract:
1. A portable blood component analysis device, comprising: a microfluidic unit including: a sample chamber defined in a first longitudinal channel having a first major axis and a second longitudinal channel having a second major axis in communication with the first longitudinal channel, with the second major axis crossing the first major axis, the first longitudinal channel being configured to convey blood into and out of the sample chamber, the sample chamber having a surface augmentation features with biospecific surface configured to capture particles from blood, the surface augmentation feature including a plurality of surface augmentation particles or beads loaded into the sample chamber through the second longitudinal channel using a loading fluid; and a restraining structure including a plurality of microposts forming a fence-like structure around a portion of the sample chamber and configured to retain the plurality of surface augmentation particles in the sample chamber and allow the loading fluid and the blood to exit the sample chamber through the restraining structure; and an analyzer component having a signal detector and a receiving slot configured to receive the microfluidic unit and align the sample chamber with the signal detector.
