Abstract: In this work, we show how field emission–scanning electron microscopy (FE-SEM) can be a useful tool for the study of self-assembled monolayer systems. We have carried out a comparative study using FE-SEM and atomic force microscopy (AFM) to assess the morphology and coverage of self-assembled monolayers (SAM) on different substrates. The results show that FE-SEM images present the same qualitative information obtained by AFM images when the SAM is deposited on a smooth substrate (e.g., mica). Further experiments with rough substrates (e.g., Al grains on glass) show that FE-SEM is capable of unambiguously identifying SAMs on any type of substrate, whereas AFM has significant difficulties in identifying SAMs on rough surfaces.

A simple and facile preparation approach of gold-silver nanoframes is described based on triangular silver nanoplates. HAuCl4was used as etching agent and added to boiling nanoplates suspension under stirring. Especially, when different concentrations of HAuCl4was employed, various etching happened and corresponding morphology of gold-silver nanoframes were acquired. The properties of nanoframes were characterized by scanning electron microscopy (SEM) and UV-vis spectra. Then the nanoframes were self-assembled onto the silicon treated with APTMS and used as SERS substrates for detecting p-ATP molecules. The results indicated that nanoframes showed better SERS effects than nanoplates.
