Poly-d-lysine promotes attachment of viable chromaffin cells to metals and Teflon AF Au, but not to DLC:N. Each substrate was treated with poly-d-lysine as described in Section 2. (A) Cell density (cells/mm2) is presented as the mean ± SE from at least 40 images taken from 4 samples of each substrate in two different cell preparations. ** Indicates the sample differs from DLC:N with p < 0.01. Micrographs of chromaffin cells adherent to polylysine-treated (B) DLC:N, (C) ITO, (D) Pt, (E) Au, (F) Teflon AF. Scale Bar represents 50 µm.
