Nanoscale Piezoelectric Properties of Self-Assembled Fmoc-FF Peptide Fibrous Networks

摘要: Fibrous peptide networks, such as the structural framework of self-assembled fluorenylmethyloxycarbonyl diphenylalanine (Fmoc–FF) nanofibrils, have mechanical properties that could successfully mimic natural tissues, making them promising materials for tissue engineering scaffolds. These nanomaterials been determined to exhibit shear piezoelectricity using piezoresponse force microscopy, previously reported FF nanotubes. Structural analyses Fmoc–FF nanofibrils suggest observed piezoelectric response may result from noncentrosymmetric nature an underlying β-sheet topology. The fibrous networks is advantageous a range biomedical applications where electrical or stimuli are required.
