FIG. 7

Correlation (linear fit) of ELP thickness and fluorescence peak intensities of SPFS angular scans after the stepwise binding of C-ELPs (◊) and unlabeled ELPs (●), respectively, attachment on activated COOH-(EG)6 SAMs with seven different graft densities at a solution ionic strength of 10 mM. Points 1, 2, and 3 represent the three ELPs matrices shown in Fig. 6 for stretching measurements, while the other points were prepared for stimuli response measurements shown in Fig. 9.
