Comparative assessment of the sensitivity of localized surface plasmon resonance transducers and interference‐based Fabry‐Pérot transducers

What is it about?

Typically, there are multiple, competing ways of sensing an analyte. To meaningfully advance the field, different techniques must be compared and assessed critically. In this invited paper, we quantitatively compared LSPR sensors, to those employing thin-film interference in a Fabry-Pérot interferometer configuration. Employing a combination of experimental and simulated data, we concluded that for nm-scale recognition and analyte layers, LSPR transducers offer higher sensitivities, especially in wet conditions; for thicker layers, interference transducers become favorable.
