Figure 4

Confocal fluorescence image of a binary passivation layer comprised of PEI-DTC (15-μm lines) and H2N-C11 thiol (5-μm lines). (a) Freshly prepared binary patterns labeled with FITC; (b) binary patterns labeled with FITC after 1 week exposure to air at 4 °C. (c) Fluorescence intensity linescans of images (a) and (b), freshly labeled (■) and 1 week later (□), respectively.
