Cytoskeletal Self FocusingDel Giudice

As described in Chapter 6, a group of scientists from the University of Milan have applied the mathematical tools of "many body problems" to the activities of biomolecular dipoles. Del Giudice, Doglia, Milani and Vitiello (1985, 1982) have used quantum field theory to describe the electret state of biological systems (ordered water surrounding linear biomolecules) and determined that there exists a strong likelihood for the propagation of particle-like waves in biomolecules. Further, the ordering of water should lead to self-focusing of electromagnetic energy into filamentous beams excluded by the ordered symmetry. For ordered cytoplasm, they calculate the diameter for the confinement and propagation of particle-like waves (massless bosons, or solitons) in biomolecules to be about 15 nanometers, exactly the inner diameter of microtubules.

The proposal by the Milan group has a number of implications. Confinement within filamentous regions excluded from water would favor the propagation of electromagnetic energy in biological systems, and provide a mechanism for alignment and communication (the "Indian rope trick"). Further, cytoskeletal polymers may be capable of capturing and utilizing ambient or biologically generated electromagnetic energy. One possible example is infrared energy which is routinely generated by dipoles in biological molecules. This energy is generally believed to be dissipated into heat within the aqueous cytoplasm, however "self-focusing" could utilize this energy productively in a communicative medium. The Milan model also includes lateral force generation by focused energy within cytoskeletal filaments which would be useful in biomolecular maneuvering and communication.
