Abstract
The invention relates to an SPR sensor array comprising a plurality of SPR sensor surface areas ( ) arranged on a substrate ( ) in a two-dimensional matrix located in a plane to which the SPR sensor surface areas ( ) are parallel and whereby radiation capable of exciting surface plasmons in the SPR sensor surface areas ( ) under specific physical conditions can be guided through the substrate ( ) to be reflected from the SPR sensor surface areas, as well as separating means ( ) for separating each SPR sensor surface area ( ) from its neighboring SPR sensor surface area ( ), wherein the separating means ( ) and SPR sensor surface areas ( ) are provided such that at least outside of surface plasmon resonance occurring in the SPR sensor surface areas ( ) the radiation ( ) guided through the substrate ( ) is reflected in the region of the separating means to a different degree than in the region of the SPR sensor surface areas ( ) to create a contrast between the separating means ( ) and the SPR sensor surface areas ( ) at least outside of surface plasmon resonance occurring in the SPR sensor surface areas ( ) in the radiation reflected by the SPR sensor surface areas ( ) and the separating means ( ).
