I. Peptides are easily synthesized using solid-phase meth- ods, which allows for sequence-specific modifications at the molecular level [6]. II. Additional peptide functionalization can easily be per- formed by introducing compounds such as antibodies, enzymes, magnetic particles, or fluorescent compounds to the peptide structure [7]. III. Custom supramolecular structures can be designed through engineering of self-assembled peptide building blocks [6]. IV. Naturally occurring self-assembly motifs present in pro- teins such as ␣-helices, ␤-sheets, and coiled-coils can be used to drive the self-assembly process [8]. V. Peptides are the most attractive biomaterials for regen- erative scaffolds, since the main ‘‘signaling language’’ in the extracellular matrix (ECM) is mediated via peptide epitopes [9]. VI. Self-assembly is important in cell-penetrating peptide (CPP) mechanisms, which play a major role in introduc- ing drugs inside cell membranes and translocating genes inside a nucleus
