Area of Science:

  • Molecular systems biology
  • Biotechnology
  • Complex systems

Background:

  • Spatially resolved studies of cell-free molecular systems are enabled by sensitive fluorescence detection.
  • Advancements focus on open, interacting, spatially-resolved amplification systems using silicon microreactor technology.
  • A hardware platform for individual-based simulation of these systems is under development.

Purpose of the Study:

  • To realize open microflow reactors in zero, one, and two dimensions for long-term studies with limited biochemical materials.
  • To construct interacting model systems with predator-prey and cooperative amplification dynamics using the 3SR reaction.
  • To develop a hardware platform for high-speed, individual-based simulation of molecular populations.

Main Methods:

  • Development of open microflow reactors (0D, 1D, 2D).
  • Utilizing the primer-directed 3SR reaction for DNA and RNA amplification.
  • Designing and constructing the NGEN massively parallel processor-configurable computer for hardware simulation.

Main Results:

  • Realization of microreactors enabling long-time studies with minimal biochemicals.
  • Construction of interacting model systems exhibiting predator-prey and cooperative amplification.
  • NGEN computer enables high-speed hardware simulation of large, locally interacting molecular populations.

Conclusions:

  • Individual-based modeling is crucial for understanding molecular evolution due to distinct sequence polymers.
  • Simulations reveal self-replicating spots stabilize cooperative amplification in evolving systems.
  • Experimental systems are expected to exhibit oscillatory kinetics and pattern formation, impacting evolution and providing insights for molecular biotechnology optimization.
