VERFAHREN ZUR SCHAFFUNG EINES ARTIKELS MIT EINER NADEL EINES MIKROARRAYSPOTTERS

摘要

The invention relates to the provision of an article and a method of forming an article with a surface which can have at least one sub-layer and a top layer of material. At least one part of the top layer is selectively removed to expose at least one sub-layer and/or the surface of the substrate and allow the functionality of the sub-layer and/or surface to be utilised in the area(s) where it is exposed. The top layer, where it remains, acts as a barrier to the sub-layer and/or surface being exposed to the surrounding environment. Typically parts of the top layer are removed in a patterned manner to provide a series of predefined areas at which the sub-layer or sub-layers are selectively exposed.
