Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adom201400394-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>A refractometric biosensor with a broad range of figure of merit (FoM) is achieved in aqueous media using plasmonic crystals on a CYTOP cladding. Counterintuitively, it is demonstrated that the conventionally defined FoM is not an appropriate benchmark for biosensing performance evaluation due to the divergence of the bulk and surface sensitivities. A new surface sensitivity is thus recommended. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh3xbt4bs8" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
