AFM images (left) and amplitude profiles (right) for a 10 nm Au film on N. palea. (a) Film as deposited. (b) Coarsening of surface texture observed after annealing 10 nm Au film in air at 400°C for 60 min. The thick vertical bands are the Au coated weft costae transverse to the long axis of the diatom. Amplitude profiles were obtained in the valleys where the pores reside.
