Detection of proteins in various sample material (e.g. human plasma) especially is used in human medicine for testing of inflammation, allergies, cardiovascular parameters etc. Current testing technologies are on the one hand laboratory tests such as ELISA (enzyme-linked immunosorbent assay), which are quite expensive and do not deliver quick results. On the other hand point-of-care testing methods like lateral flow immuno assays lack sensitivity and quantitative detection. In addition both technologies are not able to detect more than one parameter.
