"Bio Photon : Allelopathy" 2007

Organisms and cells emit an extremely faint light, known as biophoton, imperceptible to the naked eye. This piece uses a photomultiplier tube (PMT) like those at the Super-Kamiokande neutrino observatory to extract the bio-photons released as a seedling sprouts. Further, the number emitted photons (light in particle form) are projected graphically, in real-time. This particular installation examines the difference in biophoton emissions between various species of plants.
