Nanoparticle Arrays and Gratings

The adsorbates were applied through incubation of the cleaned SERS substrates in a 10 nM solution of Rhodamine 6G in water. SERS intensities 

A similar approach to substrate preparation was adopted by Tessier et al. [38]. Concentrated gold nanoparticles (25 nm) and latex microspheres (630 nm) were mixed together and deposited on a microscope slide. A sec- 

The SERS spectra from an organic analyte deposited on the substrate were found to show a enhancement factor of 104, which is comparable to the enhancement obtained from two-dimensional silver gratings produced by electron beam lithography by Kahl et al. [39]. Like the self-assembled three-dimensional opal gratings, the templated gratings provide clear practical advantages over ordered substrates produced by more complex and expensive methods. The results reported are summarized in Table 10.2. From the
