Optical properties of different type of surface treatments of titanium biomaterial as polishing, grinding, and chemical etching are investigated in details. The main aim of this study is in sensing the organisation of nano-scale fibrinogen and oligonugleotides adhered on biomaterial surface. Thus permittivity change and the fluctuation in optical roughness of treated titanium surface, when titanium surface is subjected to the contamination of buffer fractions as well as to the contamination of human plasma fibrinogen fraction, are investigated through optical window of a cuvette by using diffractive optical element based sensor. During the progress of this work also optical ellipsometry as a corroborative method was used to verify the attachment of the molecules on the biomaterial surface.
