Fig. 2. AFM images of seeds and fibre-like micelles of PFDMS₄₄-b-PDMS₂₅₀-b-P3OT₁₇ on gold surfaces. The gold coated silicon slides were immersed for 2 h in seeds solution (A) 0.02 μg ml^–1, (B) 0.1 μg ml^–1 and (C) 1 μg ml^–1. (D) Variation in number of seeds as function of seeds solution concentration. (E–G) The micelles were grown from 0.02 μg ml^–1 immobilised seeds on Au surfaces by immersion for 1 day in unimer solutions with concentrations (E) 1, (F) 2 and (G) 4 μg ml^–1. (H) Variation in length of micelles after 1 day as a function of unimer solution concentration. (I–K) Slow growth of the micelles from 0.005 μg ml^–1 seeds on gold surfaces and immersion in 0.5 μg ml^–1 of unimers solution for (I) 2, (J) 6 and (K) 10 days. (L) Variation in length of micelles as function of immersion time.
