Article Synopsis
- Self-assembled monolayers (SAMs) of functionalized azobenzene thiols were examined on various substrates using Surface-Enhanced Raman Spectroscopy (SERS) in the near-infrared region, revealing significant variations in SERS effects based on the substrate and treatment times.
- The optimal conditions for etching and deposition were found to be 5 seconds in a 1:1 HNO3 solution and 40 seconds in 0.1 M Ag(NH3)2NO3, respectively, enhancing the SERS response when a layer of silver mirror was applied atop the SAMs.
- Scanning electron microscopy (SEM) identified that a specific surface roughness—around 100 nm—is crucial for maximizing the S
