Title: Nanoscale Communication: Energy and Information


1
Nanoscale CommunicationEnergy 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

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?

Nanoscale CommunicationEnergy 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

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
