ABSTRACT: SPR
sensor with matrix arrangement of nanostructured golden spots enables both the
study of low concentrations of substances in solution and the acquisition of
information on the spatial layout of the diagnosed medium in solution. The
linear response of this sensor was experimentally specified for standard
solutions of alcohols in a concentration range of 0.01 - 0.5 wt%. The influence
of signal noise generated by carrier substance flowing through sensing dots has
been removed by data processing. This approach enables to determine refractive
index changes less than 3 × 10-6.
