Complex Fluids, Biomimetic Materials

Our primary research interest lies in finding simple and elegant ways to control the structures of materials at different length scales precisely. Multi-scale hierarchical structures are found abundantly in nature for surprisingly different purposes. For example, the amazing climbing abilities of geckos on different surfaces can be attributed to a hierarchical structure on their food pads. Hierarchical structures on lotus leaf make the leaf surface both superhydrophobic and self-cleaning. In another totally different situation, Morpho butterflies show brilliant iridescent colors arising from very delicate and hierarchical structures on their wing scales. All those structures found in nature are formed by the so-called “bottom up” method, self assembly of nano-scale building blocks into functional macroscopic structures. Taking advantage of their best properties individually and putting them together in a synergic way is, however, not always an easy task for humankind. Our goal is to study and understand the fundamental principles of self- and guided- assembly of nano-“building blocks”, such as polymers, nanoparticles, cells, biomolecules, etc. Based on our understandings, we will then develop economic routes (by integrating both bottom-up and top-down methods) to fabricate organic-inorganic hybrid materials with both hierarchical structures and multiple functionalities. Those revolutionary materials will have impacts on the development of more efficient photovoltaics, photonic crystals, multi-functional and environmentally adaptive nanomotors, as well as biomedical diagnostic/therapeutic systems.
