Solid state approach in biophoton research.

ABSTRACT

Main characteristics of the delayed luminescence (DL) emitted in the seconds range from biological systems is analyzed. The correlation between change in DL and cell's organization, and similarity with some characteristics of DL from solid state system suggest to connect DL in biological system to decay of collective electron states, formed during energy and charge transport along the macromolecular ordered structures which form the cell. Results of a proposed soliton model are discussed, together with some phenomenological evidence which emphasize the possibility of using DL measurements as an intrinsic probe in biophysical investigations.
