Biologically programmed synthesis of core-shell CdSe/ZnS nanocrystals.

Here we report a biomimetic method to synthesize core-shell CdSe/ZnS semiconductor nanocrystals using a bi-functional peptide; the resulting nanocrystals had a defect free crystallinity and a clearly observed core-shell structure; the results are significant as this is the first report of core-shell semiconductor nanocrystal synthesis using a peptide template.
