Characterization of a Bistable Switch

Problem

  • Several teams use a bistable switch but the switch is not well characterized

Goals

  • Create a bistable switch that can be added to a larger project
  • Characterize the switching mechanism

Applications

  • Projects that need to toggle between two states
  • Simple state machine




Jail Break/Treasure Hunt

 This has been voted down in favor of a different project.

Goals

  • Use a chemical attractant to move bacteria to a target
  • Use a second attractant to move them away from the first target and to a second target
  • Floresce when they reach each target

Applications

  • Neat blinky bacteria
  • Chemical finder
  • Good use of a bistable switch
  • more to come...

Project Specifics

Use a bistable switch to control the state of the cell.

Switch States

  1. Attract to target 1
  2. Attract to target 2

Flow: State 1 --> State 2 --> (halt)

Questions

  • How do we start in state 1
  • Are there more than one quorum sensing mechanisms (one for each state)

Setup

  • Take a plate media and place two groups of stationary cells a and b.
  • Each group of cells emit a different chemical attractant
  • Take a third group of cells (the hunters) that use chemotaxis to move toward cell group or target a
  • The hunters will group near the first target and activate a quorum mechanism
Quorum Mechanism:
* causes hunters to follow chemical attractant b
* causes first target to emit a florescent protien (or some visible beacon)
  • The hunters now group at target b and activate a quorum mechanism

Cops and Robbers

Similar in nature to Jail Break/Treasure Hunt.
