Proteins are one of the most important classes of biomarkers - biological molecules indicative of a disease or health of an individual. The detection of proteins is critical in a variety of tests; from the diagnosis of malaria, through the detection of heart attacks, to cancer screening and monitoring. The most common way to detect these biomarkers is to use a biochemical test known as an immunoassay, which is the basis of any pregnancy test.
