BIOCHIP AND PROCESS FOR THE PRODUCTION OF A BIOCHIP

摘要

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.
