Figure 3

Scheme of peptide-functionalized Au-coated NWs and bright field and fluorescence microscopy images. (a) Sequence of peptides labeled with carboxyfluorescein and schematic model of peptide-decorated Au-coated vertical Si NWs. (b) Scheme for fluorescence analysis of peptide-decorated Au-coated VSNEA. Bright field image (c) and corresponding fluorescence image (d) of the non-decorated VSNEA. (Black dots indicated with red arrows represent vertical NWs). Bright field image (e) and corresponding fluorescence image (f) of the peptide-decorated VSNEA (black dots indicated by red arrows again represent vertical NWs). All microscopy images are taken at a magnification of 1,000.
