Abstract：

Colorimetric　detection　of　biogenic　amines,　well-known　indicators　of　food　spoilage,　plays　an　important　role　for　monitoring　of　food　safety.　However,　common　colorimetric　sensors　for　biogenic　amines　suffer　from　low　color　resolution　or　complicated　design　and　intricate　output　for　the　end-users.　Herein,　we　explored　a　simple　but　effective　strategy　for　visual　monitoring　of　biogenic　amines　with　multiple　color　change　based　on　hydrolysis-induced　silver　metallization　reaction　to　tune　the　localized　surface　plasmon　resonance　(LSPR)　adsorption　of　Au　nanorods　(NRs).　The　color　change　and　blue　shift　of　longitudinal　LSPR　peak　of　Au　NRs　were　closely　related　to　the　concentration　of　biogenic　amines.　This　strategy　provided　a　simple,　sensitive,　robust,　nondestructive,　cost-effective,　and　user-friendly　platform　for　in　situ　evaluating　the　freshness　of　foodstuffs.　©　2016　American　Chemical　Society.
