(A) β-Sheet forming short peptides with alternating ionic complementary properties [17]. (Copyright ^© 2017 American Chemical Society) (B) Short amphiphilic β-sheet peptides that self-assemble into anti-parallel nanotapes and further aggregate into ribbons and higher order structures. In a recent paper, shorter sequences (P9-6 and P7-6) with aliphatic hydrophobic resides (in green) were demonstrated to form fibrillar structures [18]. (Copyright (2001) National Academy of Sciences.)
