Surface-tagged graphite surfaces with attached biomolecules. (a) Biotin-functionalized surface with associated streptavidin-coated quantum dot. (b) His-tag-functionalized surface with associated His-tag antibody-coated quantum dot. (c) HA-tag-functionalized surface with associated fluorophore-coated HA-tag antibody. Insets show molecular detail of graphite surface attachments. Some amino acids are drawn as spheres with corresponding letter codes for simplicity of view (H = histidine, G = glycine, A = alanine, Y = tyrosine, D = aspartic acid, P = proline, V = valine). Streptavidin crystal structure obtained from PDB 1KTR, and IgG crystal structure obtained from PDB 1IGT.
