Encapsulation of pyrene by 1 mM or 0.2 mM A6K.
Notes: (A, B) show that the densities of the A6K nanofibers and encapsulated pyrene particles were decreased compared with those in 5 mM A6K. (C) Very few nanofibers were observed in 0.2 mM A6K, with no pyrene particles encapsulated. The inserts in (A) and (C) show photographic images of the corresponding suspension. (D) The pyrene concentration decreased markedly as the concentration of A6K decreased. Scale bar, 100 nm.
