Analogous features of delayed luminescence from Acetabularia acetabulum and some solid state systems

This paper compares some features of the delayed luminescence in the second s range emitted from an unicellular alga Acetabularia acetabulum and from s ome solid state systems. Results lead us to think that such delayed lumines cence is connected to the dimension of the ordered structures present in bo th biological and solid state systems. In particular, for the biological sy stem examined, these structures are thought to be those which contribute to the dynamic formation of the cytoskeleton. (C) 2000 Elsevier Science S.A.
