  1. Nanoscale Communication:Energy and Information Tap the existing world of biological nanotechnology by constructing molecular level, functional interfaces between living systems and synthetic technology Domesticate life at the molecular and cellular level Develop design and fabrication principles that enable the construction of synthetic devices, with capabilities that rival those of living systems Bottom-up design and construction

  2. Two Nanoscale Revolutions

  3. Two Nanoscale Revolutions Technology Biology • Technology, by human design • Nanoscale dimensions beginning to be achieved • Nanoscale properties harnessed in isolated examples • Very limited capabilities compared with living systems • Self-evolving • Scientific understanding by discovery • Intrinsically nanoscale • Innumerable unique properties • Capabilities generally can not be harnessed

  4. Existence is Established All aspects of life are naturally emergent physical properties • What is it about living systems that enables them to perform such tasks? • What is the technology? • Can similar levels of functionality be engineered into synthetic systems? • Can these functionalities be harnessed? • Can living and nonliving be integrated?

  5. Nanoscale Communication:Energy and Information 5.1 Interfacing biological and nonbiological 5.2 Nano-macro junctions 5.3 Energy transduction at the nanoscale 5.4 Functional nanoscale systems and colonies

  6. 5.1 Integrating living and nonliving • Actively communicate with and direct cellular behavior • Real-time two-way communication as in living organism • Decode biological communication principles • Establish synthetic (molecular-level) communication with living cells • Develop minimal self-sustaining (living or nonliving) organism • Bottom-up synthetic cell • Top-down minimal cell
