The main objective of the proposed project is to investigate the anti-oxidant , protective ( and others) effects of High Density Green Photons (HDGP) on biological systems and the possibles optical manipulations at different molecular and cellular levels
The interactions between electromagnetic field and biological systems were extensivelyinvestigated, with remarkable results and advanced technologies. Nevertheless, the visible domain of the spectrum has been rather neglected, since classic physics did not allow electronic transitions induced by visible light.
Starting with the ’70 decade a research group centered around the Society of Quantum Biology (San Francisco) advanced the idea of possible “molecular activations”, different from the “electronic excitations” level. Phenomenological models have been published, based on the molecular coherence at macroscopic scale with the ability of maintaining long-lived coherence, (see the pioneering paper of Fröhlich on long range coherence in the enzyme activity). Within this group, Comorosan published the first experimental evidence for these possible “molecular activations” performing experiments on enzymes and revealing kinetics changes through low level irradiations of their substrates. A string of papers on this new phenomenology appeared in the international journals of that time period . The field expanded with the advent of new theoretical developments and of new type of technologies, in areas of free-space molecular diffraction, magnetic biomolecules, quantum optics and Josephson devices . A large new type of evidence appeared from the nanotechnology and from the biological field. Molecular films were designed displaying a surprising molecular coherence with space and time stability. The modern domain of quantum computing provided a wealth of data on biological quantum coherence and molecular superposition states. An important contribution has been put forward by Penrose in connection with molecular coherence in biological structures.
Penrose considers quantum coherence the circumstances when large numbers of particles can collectively cooperate in a single quantum state which remains essentially unentangled with its environment. This large scale quantum coherence is found in Bose-Einstein condensation (which occurs in laser action) where the entire system behaves as a whole, and in superconductors, when electrons have a way of “pairing up” in Cooper pairs, which behave as individual bosons.
Theoretical and experimental developments by the Comorosan group renewed the interes tof visible light interaction with biological structuresThe interaction between electromagnetic field and matter was long and extensively studied both in the country and also abroad.
Recently, the interaction of light with matter generated a new scientific domain known in physics as optical manipulation with the new concepts of optical matter and optical force.
