Replacing one atom or linkage in an organic molecule or polymer can dramatically affect its<br/>structure and properties. Chemists have long leveraged the power of synthesis to adjust and fine tune the properties of molecules and materials. Nanoparticles are a class of fundamental structural and functional building blocks for the construction of new materials. The properties of these materials depend on the size, shape, and composition of the constituent nanoparticles as well as their precise organization within the material. In order to fine tune the properties of the material, we must be able to carefully adjust the organization of its component nanoparticles. We are interested in using the power of synthetic chemistry to program and carefully adjust the structure and properties of hierarchical nanoparticle-based materials. This talk deals with peptide-based methods for controlling the synthesis and assembly of nanoparticles into well-defined chiral helical architectures. It will be demonstrated that the atomic make-up of the peptide constructs can be carefully adjusted and that these subtle yet purposeful modifications lead to significant structural changes to the chiral nanoparticle superstructure assembly and properties.
