Multi-parametric surface plasmon resonance (MP-SPR) utilizes full SPR angular spectral measurement at multiple wavelengths to characterize thin films properties. CVD-grown graphene films thickness and optical properties were determined. After the first initial layer thickness was found to be 0.37nm/monolayer [Jussila 2016]. Stearic acid (SA) LB-films showed approximately 2.5±0.2 nm thickness, and linear increment with increasing layer number [Granqvist 2013]. Additionally to layer properties MP-SPR measures interactions on thin films in real-time and without labels. Protein and cell samples binding on a Plasma Sprayed hydroxyapatite (HA) coating was measured [Vilardell 2016]. The non-invasive MP-SPR is proved to be an effective tool for the nanoscale metal, nanolaminate, oxide, polymer, and ceramic layers characterization in air and in liquid. Within the same measurement also material film interactions can be measured. Method high sensitivity makes MP-SPR NaviTM instruments great tool for thin films characterization.
