Talk Title: Semiconductor and Metal Nanocrystals as Plasmonic Antennas
Series: Lyman L. Handy Colloquia
Abstract: A critical need in nanotechnology is the development of new tools and methods to organize, connect, and integrate solid-state nanocomponents. I will present our recent work on the synthesis and self-assembly of nanocrystals for plasmonics, where light is propagated, manipulated, and confined by solid-state components that are smaller than the wavelength of light itself. We show the organization of polymer-grafted metal nanocrystals into nanojunction arrays that possess intense “hot spots” due to electromagnetic field localization. Nanocrystals organize into self-propagating chains resembling linear polymers, generating plasmonic homojunctions. Mixtures of nanocrystals organize into cross-propagating, branched structures that resemble copolymers to generate plasmonic heterojunctions. These hierarchical structures possess unique electromagnetic properties that rival top-down structures and demonstrate the potential of self-assembly for fabricating designer plasmonic materials. We also show that doped semiconductor nanocrystals can serve as a new class of plasmonic building blocks, where shape and carrier density can be actively tuned to engineer plasmon resonances. These examples demonstrate that nanocrystals possess unique electromagnetic properties that rival top-down structures, and the potential of self-assembly for fabricating designer plasmonic materials.

Talk Title: Bio-enabled Materials through Biomimetics Molecular Design
Series: Distinguished Lectures
Abstract: Nature has developed a wide range of ingenious solutions, which serve as valuable sources for inspiration when designing new materials and systems. Biological systems employ bio-molecular machinery tuned by evolutionary pathways to devise materials that bridges multiple length scales while providing diverse and outstanding properties. With a growing understanding of the molecular processes involved, biological principles are increasingly explored to develop novel bio-enabled approaches to materials science and engineering. The challenges in these strategies include controlling self-organization at a molecular level and thus provide control over the biological and inorganic interfaces under environmentally benign and biologically compatible conditions.
Proteins are key players in bio-molecular machinery by their ability to perform various tasks based on their functional specificity, their precise molecular recognition and their self-assembly capabilities. In addition to their role in biomineralization, proteins perform a wide spectrum of functions ranging from catalysis to self-regulation. Our inspiration has been to decode the foundations provided in biology`s highly organized and multifunctional structures and, thereby, to design advanced materials using biological principles. This results in a core of engineering well-defined peptide/protein based inorganic interfaces that serve useful functions (Fig. 1). In my talk, I will summarize the materials directed evolution of peptides by bridging combinatorial screening protocols to an engineered design for the targeted property. Building upon the modularity of protein domains, I will discuss the bio-enabled material and systems design approach, which deploy through single to multifunctional chimeric peptides or recombinant fusion proteins. With an extensive array of multifunctional molecular units, this approach promises to provide solutions to technological and medical areas that are built upon tunable interfacial interactions at the biomolecular-material interface. Specific examples will include i) bio-functionalization of surfaces, ii) developing multifunctional protein/peptide based hybrid nanoprobes for sensing and targeting, iii) addressable protein immobilization, and iv) bio-nano-fabrication routes for peptide enabled material synthesis and mineralization. Using biomineralization as an example, I will address: i) how combinatorial peptide design can be evolved over cycles of peptide generation towards translating mineralization formation capability to development of novel restorative and regenerative materials, ii) how material specific peptides can be explored in designing bacteria to mimic the material formation ability of cellular proteins through synthetic biology. The funding sources greatly appreciated are NIH-NIAMS, KU Internal & Endowment Funding Sources, LSDF, UW- CGF, NSF-BioMaterials, MRSEC at GEMSEC-UW and TUBITAK-International Office.
