SPR sensor surface support

The invention relates to a surface plasmon resonance (SPR) sensor surface support comprising a multitude of SPR sensor surfaces that are parallelly arranged in a plane on a substrate. Radiation for exciting surface plasmons can be directed through the substrate in order to be reflected by the SPR sensor surfaces. The sensor surface support also comprises separating means for separating the individual SPR sensor surfaces from the respectively adjacent SPR sensor areas, whereby the separating means for each SPR sensor surface form a respective cavity. The sensor surface support is additionally provided with a multitude of measuring areas, whereby each measuring area contains one or more SPR sensor surfaces, and at least one measuring area is surrounded by an insulating area, which does not contain any separating means and is configured for accommodating a sealing element in order to form, together with a volume element to be placed on the measuring area, a space over at the at least one measuring area, said space being isolated from adjacent measuring areas.
