* The gold layer was applied through pulsed laser deposition, maintaining the nanostructure's detail, with varying thicknesses achieved based on how long we deposited the gold. *! 
* Testing these new substrates with benzenethiol showed significantly enhanced SERS signals compared to traditional flat gold surfaces, highlighting their potential advantages for spectroscopy applications. *!
