• Built three types of cells that express fluorescent protein when presented with a certain concentration of autoinducer (high, medium, low)
• Mixture of cells can produce a bullseye when a sender cell is place in the middle
• Bi-directional communication might be an interesting topic to investigate
• Use same mechanism, but make cells express different protein such as adhesin (cells only stick together when they detect autoinducer)

• Paper discusses purposely mutating pathways to optimize genetic circuits
• Fluorescent screening used to discover which mutations made the nonfunctional gate work as intended
• Good method, but no apparent future work
