ABSTRACT:
A surface plasmon resonance (SPR) assay apparatus is provided, in which a flow channel, a sensing surface and an optical assay unit are used. The sensing surface is associated with the flow channel, and contacted by a sample in the flow channel. The optical assay unit applies illuminating light to the sensing surface in contact with the sample, and measures reaction of the sample according to the illuminating light being reflected. A fluid dispenser, after measuring the reaction of the binding, introduces washing fluid on the sensing surface to wash the sensing surface. A cleanliness evaluator, according to the assay signal in the washing, checks whether a regenerated state of the sensing surface is such that the sensing surface is regenerated to an initial state prior to the reaction of the binding. A controller ends up the washing if the sensing surface has been regenerated to the initial state.
