| abstract |
The invention relates to a biochip ( 5 ) comprising a porous support ( 10 ), wherein the porous support ( 10 ) comprises at least one surface coated with a coating, preferably a polymer coating ( 20 ), wherein the coating is patterned with a micro compartments ( 25 ) pattern, with the support providing a bottom surface to the compartments and the coating providing edges to the compartments, and wherein the pattern comprises at least 400 compartments per mm2. The biochip ( 5 ) can be obtained by a process comprising providing a porous support ( 10 ); coating at least one surface of the support with a coating ( 20 ); arranging between the coated surface and an ion etching device a shadow mask with a predetermined hole pattern; and ion etching at least part of the coating such that a patterned coating with micro compartments ( 25 ) is obtained. |
