Abstract
The invention relates to a sensor unit for a Surface Plasmon Resonance (SPR) unit, comprising a transparent sensor structure forming at least one wall of a cavity, the wall being defined by a concave inner surface and a convex outer surface The inner surface is provided with a layer of a conductive material capable of supporting a surface plasmon. In the cavity there is provided a flow structure in said cavity so as to form at least one compartment for sample between the flow structure and the inner wall of the cavity. Also, a method for the detection of events at a surface by utilizing surface plasmon resonance is provided. It comprises placing a sample with an analyte of interest in a sensor unit as claimed in claim, and measuring the reflectance from said sensor unit at a single or plurality of angle/angles.
