METHOD AND DEVICE FOR DETERMINING SEVERAL ANALYSTS WITH SIMULTANEOUS INTERNAL CONTROL IN A GRAPHIC COMBINATION

摘要

The apparatus, to identify molecules or molecule classes or mixtures, has at least two surfaces on a surface which are modified chemically or physically to immobilize the molecules. One surface is for control and standardizing and the other surface is for the identification of an analyte. Both surfaces come into contact with the whole sample matrix simultaneously, on the tangential-touch-test principle. Both surfaces form a graphic array which can be scanned optically, and are evaluated together. The agents to immobilize the molecules are antibodies, antigens, DNA, RNA, enzymes, substrates, receptors, ligands and their combinations.
