Switching on SERS from SERS-Inactive Substrates through Simple Electrodeposition Guided by Defective Molecular Layer

Key Points

• The aim is to enhance Raman scattering intensity on previously inactive substrates using electrodeposition.
• Utilized electrodeposition to modify substrate surfaces
• Applied techniques to create plasmonic surfaces
• Assessed the intensity of Raman scattering before and after treatment
• Significant increase in Raman scattering intensity observed
• Successful activation of previously inactive substrates for molecular identification
• Demonstrated efficiency of the method in enhancing electromagnetic signals
