And the optical device is used for performing alignment and straightening effects on the laser generated by the laser generator so as to excite more positive ions and more negative ions.

The scheme of using ionized water daughter as medicine for treating coronavirus has obvious curative effect. Since the virus attacks the cells by means of the negative ions carried by the virus, the electronegativity of the virus can be neutralized by inputting a large amount of positive ions into the lung through a lung treatment device. As a result, the virus loses the function of attacking cells, that is, the virus has a possibility of greatly reducing the ability of attacking cells by using the principle of combining positive ions and negative ions of virions.
1. Partial discussion of the electronegativity of viruses
RNA has a phosphoribosyl skeleton and bases, but bases are poor in hydrophilicity, so that the phosphoribosyl skeleton is generally exposed on the surface of a molecule, the bases are wrapped inside and are stabilized by base stacking force (in fact, pi-pi delocalized electron interaction) and hydrogen bonds and are not easy to ionize, and the phosphate groups are exposed on the surface of the molecule and are negatively charged, so that the whole RNA molecule is negatively charged.
2. A laser can be used to cleave clusters of water molecules. By using the resonance principle, laser with proper wavelength can crack huge water molecule groups with high efficiency. For example, a 1.94 micron or 2.96 micron laser is used to treat the body of water. By laser processing, it is possible to ionize water molecular clusters of huge molecular weight and generate plasma with high efficiency.
3. The plasma thus generated can be decomposed and form two ion flows, positive and negative.
4. The presence in the plasma is essentially of bare ions and electrons, as well as atomic molecules excited by electron collisions. Because of the collision process to break chemical bonds, we see a large number of individual atoms that are extremely chemically reactive, especially atoms like F can corrode almost all substances. Furthermore, even if the elements are chemically inert, they have the ability to attack physically, i.e. ions hit the solid surface, knock atoms out of the solid surface directly, or activate chemical bonds of the solid, catalyzing various chemical reactions.
5. The plasma has strong chemical activity, so that the biological properties of the virus can be greatly changed, particularly, positive ions in the plasma can neutralize the negative electricity of a virus shell, the capability of the virus to attack cells is reduced, and the virus is killed.
Summarizing the above arguments, the laser decomposes the water molecule groups to a great extent, obtaining a plasma stream (up to several billion plasma pairs per cubic centimeter) with a very high ion content; the positive ions are utilized to treat the lung of a virus patient or used for treating the virus environment, and the positive ions neutralize the negative charges carried by the virus shell in the contact of the positive ions and the virosome in the process, so that the virus attack capacity can be greatly reduced, and the device can receive remarkable curative effect on most virus patients and extremely good environment disinfection effect.
