Chain For Laser And Bio Portion Of The Molecule, Key Local Role In Analysis And Applied Research

Laser is being applied widely in biology and medicine area. But till present, people have little knowledge about the micro-mechanism of laser-bioeffect. Thus it is very important and necessary to study these effects in order to improve and develop the applications of laser in life science.This research is built on a model that classifies the bio-molecules into two systems,harmonic oscillators and bipolar inharmonic oscillators. It discusses the local interaction of laser on certain links and bonds of bio-molecule by using quantum mechanics based on laser theory and bio-molecule structure. By using the laser-inharmonic oscillator system model, it was concluded that the bipolar inharmonic oscillator will be drastically stimulated when the laser reaches near-resonance frequency, the relative movements and total system momentum of the molecules will also rapidly increase, cause easy breaking of the bonds and links.The laser application on C-C bond of the fibrinogen molecules was studied by using numerical analysis method. The physical theory of using intra-vascular laser irradiation on blood to change the fluid dynamic characters of blood thus to cure heart and brain blood vessel diseases was explained by using clinical research data. The study also discussed the different laser bio-effects of carbon dioxide laser, He-Ne laser, and green laser on C-C bonds of the fibrinogen molecules, hoping to provide more theoretical insights and references to laser medicine.The study also covers the laser application on YunNan rice seed preparation. The Laser-Induced-Seed-Metamorphosis (LISM) was studied by applying laser and electro-magnetic field on Yunnan Sanjiao Fragrant Glutinous Rice, which is of good rice quality, peculiar fragrance, but low reproduction rate, high individual height, and very limited locality. The experiment shows that though it was very hard, a small number of Laser-Induced-Seed-Metamorphosis (LISM) did been observed among the Yunnan Sanjiao Fragrant Glutinous Rice seeds which were applied by the laserand electro-magnetic field. An analysis was provided on the mechanics of such laser induced rice seed metamorphosis.The different bio-effects of laser and electro-magnetic field on LISM were studied, and an analysis is provided base on comparison of results.Assisted with laser bio-interaction theory and application research, the Raman Spectroscopy study was applied on the aforementioned experiments on rice seeds. We found there was a slightly difference between the laser and electric filed processed rice seeds and the unprocessed rice seeds. This shows that although it is very hard to introduce LISM on the Yunnan Sanjiao Fragrant Glutinous Rice seeds, there is a slight possibility of success. A comparison and a theoretical analysis were made between the laser spectroscopy analysis and field experiment results.The bio-single molecule dynamics has made great progresses in theories and experiments during the past ten years. Some peculiar dynamical and thermo-dynamical characters were found among the single bio-molecules. Weaponed with the existing results and discoveries in this area, the study of laser-biomolecular interaction would be the new direction for future researches.
