Direct Hierarchical Assemblies Using Secondary Interactions

With rapid developments in chemistry, many molecular building blocks can be readily synthesized. Controlled assembly of functional building blocks over multiple length scales has great potential to advance technologies and will impact human health, renewable energy and enviorment. However, generating hierarchically structured materials in a manner similar to that seen in nature represents a fundamental scientific challenge. I will focus on some recent advances in directed self-assemblies over multiple length scales in multi-component systems including peptides and proteins, nanoparticles, organic semiconductors and polymers. These efforts can lead to functional materials with features down to the molecular level and contain inherent biological, electronic and optical properties for catalyst, filters, lithography, optical devices and regenerative medicines. Equally important, we focus our efforts on achieving this using secondary interactions to ensure long-term sustainability. Based on our experiences, I will also discuss some opportunities these studies present as well as challenges to advance the field of nanomaterials.


Speaker Background

Professor Ting Xu received a M.S in Polymer Physics from Changchun Institute of Applied Chemistry, Chinese Academy of Science in 1999 and a Ph.D from the Department of Polymer Science and Engineering at the University of Massachusetts, Amherst in 2004. She was a joint postdoctoral fellow between the University of Pennsylvania and the Cold Neutrons for Biology and Technology (CNBT) Partnership Program at NIST before she jointed UC, Berkeley in January 2007. Her current research efforts focus on fundamentally understanding the hierarchical self-assembly of complex systems involving de novo designed peptide and peptidomimetics, block copolymers and nanoparticles and apply it toward generating functional materials exhibiting novel properties.
