Design of High Sensitivity Cellulose Filter Paper-based SERS Flexible Substrate for Testing Harmful Rust of Bronze Ware

Abstract Surface-enhanced Raman scattering (SERS), a simple, highly sensitive, and fast analytical method can be used to detect corrosion components on the surface of bronze ware, difficult problem. The silver mirror reaction is suggested for depositing precious metal nanoparticles cellulose filter paper in order create quick, easy, low-cost approach creating SERS substrates. After an 8-minute deposition time, optical microscopy scanning electron (SEM) revealed uniform dispersion metals paper. To examine characteristics substrate, copper chloride oxide, main ingredient damaging rust trace was as probe molecule. findings show that with distribution achieves best performance. flexible substrate enables effective analysis surfaces.
