Data potential of bio/photon

While I am not a scientist, my teenage daughter hold an interest in a career related to biophotonics and I have some related conversations with friends. I recall seeing a webpage flash or pdf, etc. a few months back that described the potential data storage of a single biophoton. I first suspected that I had seen it at Lifescientists.de or Quantumconsciousness.org but can't be sure. If I remember correctly, there was an illustration of a microtubule array and then a note of a potential of either 2 or 4 kb or MB. If someone could point me in the right direction so that I could link some notes to this source, that would be great. Also, an explanation of the implications of a photon ability and necessity to carry information would be useful.

Thanks for your help
