SURFACE PLASMON RESONANCE INSTRUMENT - MODIFICATIONS IN MEASUREMENT TECHNIQUES TO IMPROVE SENSITIVITY AND PROVIDE FOR MORE ECONOMICAL TESTING

摘要

It replaces the plain gold sputter coated slide (50 nm for 638 ran laser light source) with a similarly coated (gold slide) over which an additional dielectric layer of some plastic material is coated by solution and evaporation. Thus, there are two interfaces between the substance analysed and the prism now.
