A novel method to prepare nanoporous silver structures (NPSs) is introduced. Soluble starch is used as the in situ template, and an aqueous AgNO 3 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.
