CAREER: Self-assembly of functional systems within live cellsThe objective of this proposal is to develop a fundamentally new way to construct heterogeneous functional systems via self-assembly inside living cells. The approach is to fabricate functional inorganic nano-scale components, to microinject them into live cells, and to allow them to self-assemble into an interconnected structure. The self-assembly is driven by and programmed with specific covalent and supramolecular bonds resultant from the interaction of biomolecules (e.g. polypeptides) and inorganic surfaces. Intellectual merit: The project develops a fundamental understanding of biomolecule/inorganic surface interactions and develops a methodology to use the molecules to self-assemble structures, made from parts originating in incompatible fabrication processes, from the bottom-up. The project pioneers a new paradigm in constructing artificial structures inside live cells and provides a new venue for characterization of live cells from within. This ability is critical in expanding the current understanding of biology and providing a new tool for studying biology at the single cell level. Broader Impact: One of the main objectives of this project is to train a new generation of engineers that are capable of conducting research at the interface between electrical engineering and biology. This training is provided by their active participation in the research program at high school, undergraduate, and graduate levels and is augmented by development of new courses in experimental nanofabrication, self-assembly, and engineering design of cells. One of the main focuses of the outreach program is to connect with the Native American high school students of the State of Washington and to encourage their active participation in research.

职业：活细胞内功能系统的自组装本提案的目的是开发一种通过活细胞内自组装构建异质功能系统的全新方法。该方法是制造功能性无机纳米级组件，将其微注射到活细胞中，并使其自组装成相互连接的结构。自组装由生物分子（例如多肽）和无机表面的相互作用产生的特定共价键和超分子键驱动和编程。智力优点：该项目开发了生物分子/无机表面相互作用的基本理解，并开发了一种方法，使用分子自组装结构，由源自不相容制造工艺的部件自下而上制成。该项目开创了在活细胞内构建人工结构的新范式，并为从内部表征活细胞提供了新的场所。这种能力对于扩大目前对生物学的理解并为在单细胞水平上研究生物学提供新的工具至关重要。更广泛的影响：该项目的主要目标之一是培养新一代的工程师，能够在电气工程和生物学之间的接口进行研究。这种培训是通过他们积极参与高中，本科和研究生阶段的研究计划提供的，并通过开发实验纳米纤维，自组装和细胞工程设计的新课程来增强。外展计划的主要重点之一是与华盛顿州的美洲土著高中生建立联系，并鼓励他们积极参与研究。
