Abstract:
1. A device for manipulation of limited quantities of a liquid comprising: the device comprises at least one solid; the solid has surface areas in which different capillary forces act comprising: a plurality of first surface areas that have a microstructured and/or nanostructured surface, and are spaced apart from each other; each microstructured and/or nanostructured surface has a plurality of regularly arranged structure elements, wherein all of the plurality of regularly arranged structure elements are equal in shape to each other in each of said first surface areas, wherein the shape of the plurality of regularly arranged structure elements in one of said plurality of first surface areas is different than all of the plurality of regularly arranged structure elements in the remaining first surface areas; the solid and the plurality of regularly arranged structure elements in each of said plurality of first surface areas consist of one material and are connected to one another in one piece; the plurality of regularly arranged structure elements in each of said plurality of first surface areas are elevated relative to a second surface area surrounding said plurality of first surface areas; said plurality of first surface areas are provided with a liquid having reagents dissolved in said liquid, said liquid reagents becoming dried on said first surface areas; and said second surface area is flat and encompasses and abuts all of the plurality of first surface areas on all sides, and is not extending into said plurality of first surface areas, such that each of said plurality of first surface areas is a discrete area inside said second surface area; the plurality of first surface areas having higher capillary forces than the second surface area; and wherein the dried reagents of said plurality of first surface areas is dissolved by a sample dispensed onto one of said plurality of first surface areas.
