SURFACE PLASMON RESONANCE SENSOR BASED ON POLYMER SUBSTRATE

Comparative analysis of resonant curves in gas and liquid media and kinetics of their changes have been made during albumin molecule absorption. The surface plasmon resonance (SPR) sensor with prism excitation by Kretschmann scheme in thin gold film was used. Configuration for selection of incident angle was realized by mechanical scanning for sensors based on both glass and polymer substrates. It has been shown that application of plastic substrates will provide reducing manufacture cost with maintenance of high level in SPR sensor sensitivity and will enable to develop its disk version based on an integrated chip with holographic gratings for light input-output.

Keywords: surface plasmon resonance (SPR), prism SPR excitation, plastic substrate, disk format.
