Abstract
En 中文
• DSDA reduces AgNP nanogaps from 56 nm to 9.4 nm on transparent glass. • The substrate shows high spatial uniformity (CV = 7.8%) and optical accessibility. • NaCl-assisted nanoparticle redistribution and clustered hotspots boost SERS intensity. • Ex situ SEM/HRTEM support AgNP redistribution and Ag/AgCl-like interfaces.
