Production of carriers for surface plasmon resonance.

摘要

A process for the production of a carrier for surface plasmon resonance analysis (SPR) in which a metallic film comprising a layer of silver is deposited on a surface characterised in that before the film is deposited the surface is subjected to a pre-treatment comprising a step in which it is treated with an oxygen-containing gas to cause oxygen ions to enter the surface to an extent sufficient to sensitive it.
