Optical sensor based on periodic array of resonant nanopillars for real time monitoring

The results were also compared with other optical sensor (LSPR, localized surface plasmon resonance). Both sensors were assayed with the same optical and fluidic setup, in order to evaluate the differences between transducers in the same conditions. Bulk sensitivity and resolution parameters resulted 4 and 5 times better respectively for R-NP compared to LSPR.
