(A) SER spectrum from 4-aminothiophenol adsorbed on a single diatom prepared by dewetting a 10 nm Au film on Nitzschia palea frustule at 600°C for 2 h. (B) SER spectrum from 4-aminothiophenol adsorbed on 5–10 nm Au particles bound through mercaptopropyltrimethoxysilane (MPTMS) attached to a glass microscope coverslip.
