Abstract:

Recent advances in metabolic engineering have enabled autonomous, high-fidelity biomanufacturing of useful chemical, mineral, and polymer building blocks that can be leveraged in the design and fabrication of construction materials and living architectures at the human scale. This presentation will highlight research that integrates the fields of synthetic biology, microbiology, materials science, and structural engineering to design and fabricate biomimetic and living materials for the built environment. In one study, we demonstrate for the first time that calcium carbonate (CaCO3) nanoparticles can be tailored by modulating the precipitation kinetics of ureolytic microorganisms via genetic engineering. In another study, we take inspiration from antifreeze proteins to design and fabricate biomimetic ice-binding molecules that prevent freeze-thaw damage in concrete without the use of air-entraining admixtures. We also show that engineered microorganisms can be leveraged in the design of hybrid living building materials that display both biological (i.e., living, regenerative self-healing) and structural (i.e., load-bearing) function. Finally, this talk will highlight the challenges that emerge working across length scales and disciplines, as well as the grand opportunity that exists for synthetic biologists and materials engineers to work together to create never-before-imagined material solutions for critical societal problems in energy, water, and the built environment.
