Abstract：
Ordered supramolecular organisation structures comprised of Metabolic small molecules, such as short peptides, amino acids, nucleotides and vitamins, participate in almost all natural biological activities. Learning from nature, biomimicry of these natural structures will facilitate the fabrication of eco-friendly functional integrations assembled by simple bio-organic building blocks. The flexible and unique properties of the metabolite self-assemblies can be utilized for numerous bio/nano technological applications, such as the construction of soft, smart bio-organic optoelectronic devices. In addition, the intrinsic biocompatibility of the metabolite assemblies can bridge the integrating engineering and the biological world. Studies in this area can facilitate the clarification of the roles of metabolite aggregation in physiology and pathology. This may allow monitoring and sensing of a wide variety of metabolic activities, as well as analysis, and possibly interference, of the biological system, by rational design of biomimetic engineering. With these goals in mind, the metabolic integration systems can provide a promising technological tool for fundamental biology, biomedicine, bionanotechnology and advanced device engineering studies.
This talk will introduce our accumulated progress on biomimetic integration engineering, emphasising the design, preparation and self-assembly characterization of metabolite organizations, especially short peptides self-assemblies. Subsequently, our findings regarding their diverse physicochemical properties, including optical, mechanical, electric, semiconductive and piezoelectric behaviours, will be presented. Simultaneously, our ongoing studies and future plans will also be discussed.
Biography：
Dr. Kai Tao graduated his PhD from China University of Petroleum (East China), under the co-supervision of Prof. Jian R. Lu and Prof. Hai Xu, studying interfacial adsorption, self-assembly and applications of amphiphilic peptides. He then joined Prof. Ehud Gazit’s lab at Tel Aviv University for postdoctoral research, studying metabolite self-assembly and applications, mainly focusing on aromatic short peptides. Dr. Tao is currently co-supervised by Prof. Gazit and Prof. Niyazi Serdar Sariciftci in Johannes Kepler University Linz to study bio-organic integrating optoelectronics. Dr. Tao’s research interests mainly focus on molecular self-assembly and biomimetic integration engineering, smart supramolecular systems based on the small metabolic building blocks. Specifically, his experience includes preparation, characterization and application of bioinspired self-assemblies, interfacial adsorption and assembly of metabolites, interactions between bio-organic systems and inorganic constituents, supramolecular integration, bio-micro/nano functional devices fabrication and characterization, etc.
