Half-adder or Full-adder

An implementation of a half-adder or full-adder: 1-bit adder with carry

  • [http://en.wikipedia.org/wiki/Full_adder half/full adder in wikipedia]

Idea: Pattern recognition

→ Illustration of the concepts:

Main Goal:

  • Write something with a chemical on a petri plate (like ETH for example)
  • Let Bacteria grow uniformly on the plate
  • Expose the plate to a picture (black and white) of the same pattern
  • Result:
    • Bacteria gets green when pattern on the plate and picture match (light and chemical)
    • Bacteria does not express fluorescent protein when pattern on the plate and picture match (no light and no chemical)
    • Bacteria gets red when pattern on the plate and picture do not match

Implementation from the ingenieur point of view

  • Half Adder
  • = opportunity to build an AND and an XOR Gate

Implementation from the biologist point of view

  • AND Gate: presence of chemical induces the production of an inactive protein, which is activated by a second protein (produced when light is present): the first protein is then activating GFP production
  • XOR Gate: I think Marko had a good idea about that (I didn't really got it)
  • a light sensible promoter (there are some)
  • a chemical sensible promoter (chemical to be defined)
  • we would need to give a kind of first signal to the system (to don't have light reactions before a certain moment, otherwise we have to work in a dark room...), an activation signal after the bacterias have grown on the plate

Pro's & Con's

Pro's:

  • meaningful from engineering point
  • valuable parts for synthetic biology
  • experiments visually attractive
  • probably simple enough

Con's:

  • cheap copy of “bio-film” project (iGEM 2004)
  • sensational experiments, have little in common with HA
  • too simple?
