The potential of these supramolecular structures have been utilized in diverse fields including nanofabrication, drug delivery vehicles7, bio-sensing8, energy storage devices, and hydrogels for tissue engineering9, 10. The crystal structure of FF exhibits a non-centrosymmetric hexagonal space group (P61)1, 11, which allows it to possess properties like piezoelectricity12, 13, optical activity14, 15 and ferroelectricity16. Due to its low dimensional highly ordered structure it also exhibits quantum confinement17, forming quantum dots18. Self-assembled structures formed by analogues of FF such as Ac-Phe-Phe-NH2, NH2-Phe-Phe- NH2, NH2-(p-nitro-Phe)-(p-nitro-Phe)-COOH, NH2(4-phenyl-Phe)-(4-phenyl-Phe)-COOH, PEGylated tetra-phenylalanine (L6-F4), β-AspFF etc. have also resulted in tubular, fibrillar and squared plate structures respectively10, 19, 20.
