Concept
Swimmy Bacteria -- the E.coli freeze and gather when they are caught by red light.
red light on -> stop
red light off -> move
Control the E.coli's movement with light!

Experiments
light cannon
- 10/15 we wrote a picture at the solid media.(not finished yet) also we changed the arabinose concentration at the liquid media.
- 10/14 the Fluorescent lamp was the best light. we could see the on/off clearly in the solid media. we found that the thin media is better than the thicker one.
- 10/11 we changed the arabinose & S-gal's concentration & the light sorce to find the best condition.
swimmy
- 10/11 we're finding the suitable media to observe the E.coli's movement(chemotaxis).
- 8/23 we made the tsr gene parts by PCR & discussed about the locked Tsr mutants.
