Research on nanometer-sized structures has become one of the fastest growing fields of science & engineering. The application potential of nanostructures is diverse, ranging from electronic and detection materials to biomaterials. The most important reason for their popularity is that they are small. Self-assembly can be defined as the spontaneous organization of disordered molecular units into ordered structures as a consequence of specific, local interactions among the components themselves. Molecular self-assembly is referred to as a "bottom-up" approach in contrast to a "top-down" technique where the desired final structure is carved from a larger block of matter. In fact, the formation of most biological nanostructures is also driven by the self-assembly process. In recent years, an interest in manmade or artificial bionanostructures, including peptide-based self-assembled nanostructures has been intense and is expected to escalate further. Proteins are perhaps one of the most diverse and complex structures in nature. One of the most salient features of proteins is that each proteins form unique three dimensional structures, which is determined by their amino acid sequences. Moreover, we expect that artificial bionanostructures can be designed to have properties that are unprecedented in nature. Since the major driving force that underlies the formation of bionanostructures is a noncovalent self-assembly process, elaborately designed synthetic self-assembly building blocks should be one of the most suitable candidates for the construction of artificial bionanostructures. In this talk,our recent research efforts towards the understanding of peptide self-assembly process and the development of self-assembled peptide nanomaterials with bioactive andadaptableproperties will be presented.
