Abstract

original image

A novel method to prepare nanoporous silver structures (NPSs) is introduced. Soluble starch is used as the in situ template, and an aqueous AgNO3 solution is used as the silver precursor. The porous NPS film is introduced in a plasmonic sensor using the Kretschmann configuration. The obtained device responds well to environmental reflective-index changes.
