Plasmonic sensors based on periodic hole arrays in
metallic films are investigated for monitoring enzymatic
degradation of extracellular matrix. Sensors are fabricated
using a bottom-up strategy in which soft colloidal lithography
is combined with chemical gold film deposition. The resulting
plasmonic sensors show extraordinary transmission of light
supported by surface plasmon polaritons. These are highly
sensitive to refractive index changes in close proximity to the
sensor surface and are utilized for the quantitative detection of
extracellular matrix degradation.
