title: The use of ellipsometry to study adsorption on hydrogels.
abstract: This paper discusses the application of ellipsometry to film thickness measurements of materials deposited on hydrogel surface. The fundamentals of ellipsometry and modelling of ellipsometric readings are presented. A system of buffer/protein/hydrogel/metallic substrate is analysed in detail; the effects of optical properties of buffer, protein, polymer and thickness of protein film on ellipsometry readings are discussed. Cell window effects on ellipsometric results may also be quite important.
