Abstract:
A web material for combinatorial experimentation comprising a substrate in web form and multiple microwells, arranged on said substrate in a predetermined pattern and separated from each other by separating zones, each microwell comprising a bottom and an upstanding surface formed by the adjacent separating zones, wherein the composition of said bottoms on the one hand and the composition of said separating zones and upstanding surfaces on the other hand show a different hydrophilicity and in which said bottom of each of said microwells is further divided by a wall having a hydrophilicity different from the hydrophilicity of said bottom into at least two â€œbaby microwellsâ€ , said wall having a height at least 50% lower than the height of said upstanding surface.
