Blood, saliva, mucus, sweat, sputum, and other biological fluids are often hindered in their
ability to be used in point-of-care (POC) diagnostics because their assays require some form
of off-site sample pre-preparation to effectively separate biomarkers from larger components
such as cells. The rapid isolation, identification, and quantification of proteins and other
small molecules circulating in the blood plasma from larger interfering molecules are
therefore particularly important factors for optical blood diagnostic tests, in particular, when …
