Some results obtained within WP4 have been published in the scientific journal Sensors and Actuators B: Chemical in January 2017 under the title “Optical sensor based on periodic array of resonant nanopillars for realtime monitoring”
Specifically, the work performed at the laboratory scale with a preliminary optical set-up for the characterization of the optical transducer and its real time response has been reported.
The signal of the sensor was obtained with a common spectrophotometer by measuring light transmission through the resonant nanopillars surface. A flow-cell, connected to a peristaltic pump, was employed to load different refractive index solutions in order to assess the nanopillars bulk sensitivity and resolution (limit of detection). Excellent resolution and fluidic behavior were found, indicating the suitability of the resonant nanopillars system (WP4) for real time biosensing applications.
