SUMMARY:MSE Seminar: "From Nature to Engineering: Biological Blueprints for Next Generation Advanced Materials" David Kisailus - University of California - Irvine
DESCRIPTION:Organisms have derived specific sets of traits in response to common selection pressures that serve as guideposts for optimal biological designs. A prime example is the evolution of toughened structures in disparate lineages within plants\, invertebrates\, and vertebrates 1-4. Extremely tough structures can function much like armor\, battering rams\, or reinforcements that enhance the ability of organisms to win competitions\, find mates\, acquire food\, escape predation\, and withstand high winds or turbulent flow. Some of these natural systems have developed well-orchestrated strategies\, exemplified in the biological tissues of numerous animal and plant species\, to synthesize and construct materials from a limited selection of available starting materials. The resulting structures display multiscale architectures with incredible fidelity and often exhibit properties that are similar\, and frequently superior to\, mechanical properties exhibited by many engineering materials 1-4. In specific instances\, comparative analyses of multiscale structures have pinpointed which design principles have arisen convergently; when more than one evolutionary path arrives at the same solution\, we have a good indication that it is the best solution. This is required for survival under extreme conditions. We describe a few of these systems that show convergent design and describe how controlled syntheses and hierarchical assembly using organic scaffolds 5-8 lead to these integrated macroscale structures 8-12. We describe their function and translation to biomimetic and bioinspired materials used for engineering applications 13-16. \n1. “Biological and Biologically-Inspired Functional Nanostructures: Insights into Structural\, Optical\, Thermal\, and Sensing Applications”\, C-H Sung et al.\, Advanced Materials\, accepted (2025).
