(57) Abstract The backing sheet (101) is provided with a pattern (131, 132, 133) of a certain pattern of, for example, silica or cellulose by a printing method (for example, screen printing). There may be multiple routes of transport from the eluate application area (117) to the detection zone (116) and then to the waste reservoir (118). Different paths can have different liquid transfer times. Because they differ in length and / or material (eg, nitrocellulose for slow transfer by aqueous liquids and fibrous cellulose for fast transfer). Therefore, analytes and reagents deposited on the deposits (112, 113) on different paths are sequentially delivered to the detection zone. Reagents can be applied by printing. The detection zone can have an electrode assembly (105), also provided by printing, to detect the effect of the analyte. |
