Measure molecule - material interactions


MP-SPR can be utilized for layer characterization such as thickness and refractive index (RI) of the deposited layer. In addition to this also binding of molecules to the surface can be determined. This is utilized especially for new materials and coating development, such as barriers for moisture, protein, bacteria,... 

Bound mass of the adsorbed molecules can be calculated based on de Feiter equation. 



Easy calculation from the MP-SPR response can be performed.

Thickness and refractive index information show also conformation changes on the surface.

See mathematics of SPR for further information on equations governing SPR.
