Rebecca Taylor’s research and teaching focus on design and advanced manufacturing across scales. Since 2016 her group has utilized structural nucleic acid nanotechnology to create nanoscale biosensors and actuators that can interface with condensed matter, as well as molecular and cellular biosystems. In addition, she is inspired by the heart, whose contractile function is derived from exquisite structure at the molecular level up through the tissue level. To enable the creation of dynamic, engineered systems with structure across multiple scales, her group employs self-assembly methods with structural DNA nanotechnology to augment and extend existing top-down microfabrication strategies. Her teaching centers on the fundamentals of mechanical design, as well as advanced topics in large-volume manufacturing, as well the emerging design and validation methodologies for structural DNA nanotechnology. In both my research and teaching, she investigates DNA as an engineering material, and she aims to equip her students with the tools to utilize self-assembly as a powerful tool for advanced manufacturing. Her research requires highly interdisciplinary groups of scientists and engineers, and, for this reason, her group collaborates with researchers in fields including chemistry, biomedical engineering, physics, developmental biology, and cardiovascular medicine.

Research

Taylor’s research is focused in three primary domains: (1) DNA nanotechnology for molecular and cellular mechanobiology, (2) bio-inspired micro- and nanosystems and (3) advanced manufacturing.

Area 1. DNA nanotechnology for molecular and cellular mechanobiology. The application of atomic force microscopy and fluorescent molecular tension sensing in biomechanics has enabled the visualization and quantification of nanometer-scale displacements and piconewton-scale. Her group is leveraging the unique capabilities of structural DNA nanotechnology to create tools for measuring stress and strain in soft materials (supported by AFOSR YIP), investigating molecular and cellular mechanobiology of the endothelial cells lining the vasculature (collaboration with Xi Ren, BME) and platelets circulating in the blood (supported by an NIH R21 in collaboration with Marvin Slepian in BME and Cardiovascular Medicine at the University of Arizona). They are also investigating novel approaches for targeting DNA nanostructures for drug delivery and gene therapy.

Area 2. Bio-inspired micro- and nanosystems. As engineers, her group is inspired by the robustness and programmability of nucleic acids, and they are interested to extend the capabilities of nucleic acid nanotechnology. A notable contribution from her lab is the creation of self-assembling nanofilaments from building blocks of a synthetic DNA mimic called gamma-modified peptide nucleic acid (gPNA). They demonstrated that unlike DNA-based nanostructures these structures form and remain stable in harsh environments like aprotic organic solvent mixtures. With the support of her NSF CAREER award, her team is investigating the use of gPNAs in the creation of bio-inspired materials for dynamic nanotechnology with unique bioorthogonality, solution stability and resistance to enzymatic degradation.

Area 3. Biomanufacturing and  anomanufacturing. With Taylor’s background in product design, microelectromechanical systems (MEMS), molecular reconstitution assays, and DNA origami, her work spans the macro-, micro-, and nanoscales. Building on this multidisciplinary foundation, her group is working to address the advanced manufacturing challenges that will enable the combination of both top-down engineering processes with bottom-up engineering processes. For example, they have recently shown that DNA-based nanostructures can serve as flexible connectors for microscale swimmer robots, whose locomotion and swimming speeds can be tuned by connector geometry and mechanics. They are using DNA origami as a bridging material for enhancing existing self-assembly processes and for facilitating next-generation nanoscale and microscale fabrication efforts. They are also developing and utilizing workforce training tools like voice assistants that can expedite the mastery of new skills in advanced manufacturing.
