The technical principle of disinfection and sterilization of oxidation-reduction reaction in the photocatalytic disinfection device 2 is as follows:
1. the killing mechanism of the nano titanium dioxide is as follows:
TiO2photocatalysts refer to a class of substances that can be brought into a higher energy state by absorbing light and transferring the energy to a reactant to cause a chemical reaction. TiO22Due to its strong redox ability, it has the advantages of chemical and photo corrosion resistance, no toxicity, high catalytic activity, good stability and strong oxidation resistance. Semiconductor nano TiO2The band gap is composed of discontinuous low-energy valence band filled with electrons and empty high-energy conduction band, and a forbidden band (Eg) exists between the valence band and the conduction band. When light with energy equal to or larger than the forbidden band width is irradiated on the surface of a semiconductor, namely photon energy (E) of the irradiated light satisfies that E is h and more than E, electrons on a valence band are excited to jump to a conduction band, and corresponding holes are generated on the valence band, so that electron-hole pairs (E, h +) are generated on the surface of a catalyst. If the photo-generated electron-hole pairs are not separated in time, recombination occurs, and heat is released to reduce the catalytic performance of the TiO 2. If appropriate traps are presentThe agent, the recombination of electrons and holes is suppressed. In general, H is adsorbed on the surface of the catalyst20 and O2Is a capture agent of photo-generated electron-hole pair, and H adsorbed on the surface of the catalyst20 or OHAReacts with photogenerated holes to form active hydroxyl (OH) with strong oxidizing property, and photogenerated electrons react with O adsorbed on the surface2Reaction to generate superoxide ion (O)2 A)，·O2 AAnd H2Further reaction of O to form perhydroxyl (. OOH) and H2O2See the following formula,. OH,. O2OOH and H2O2Are both strong oxidizers. The OH generated by the TiO2 photocatalytic reaction has 502kJ/mol which is higher than various chemical bond energies in organic matters, such as: the bond energies of C-C, C-H, C-N, C-O, H-O, N-H are 348, 414, 306, 352, 465, 389kJ/mol, decomposing organic matters forming bacteria, and adding other active oxygen substances (O)2 A、·OOH、H2O2) The synergistic effect can quickly and effectively destroy the structures of bacteria, viruses and other microorganisms to achieve the aim of sterilization, and meanwhile, the TiO2OH generated by photocatalysis can decompose organic nutrient substances required by the growth and reproduction of bacteria, thereby inhibiting the growth and development of the bacteria, reducing the number of the bacteria to a great extent and achieving the aims of antibiosis and sterilization.
2. The killing mechanism of the nano silver is as follows:
2.1 damaging bacterial DNA
DNA molecules can replicate efficiently only in a relaxed state, and DNA molecules in a stressed state lose their ability to replicate. Any damage of DNA can affect the normal replication of genetic materials and the reproduction of organisms, and the nano silver achieves the bactericidal effect by damaging the DNA of bacteria. For example, the nano silver ensures that the Escherichia coli DNA is not randomly distributed in the nuclear region of cells any more, but is concentrated in the nuclear region to be in a tense state, and the degradation degree of the total DNA in the thalli is increased.
2.2 disruption of cell Signal transduction
Many proteins in bacteria are phosphorylated, and phosphorylation of proteins is associated with intracellular signal transduction. The phosphotyrosine of two proteins in the bacteria treated by the nano silver is dephosphorylated, namely the nano silver influences the normal signal transduction of cells. Cell lysis may not be the only cause of bacterial killing by nanosilver, which may prevent bacteria from normally surviving by affecting cell signaling.
2.3 oxidative damage by reactive oxygen radicals
The micro silver on the surface of the thallus can play a role of catalyzing an active center. Ag+Activating oxygen in air or water, generating hydroxyl radical and active oxygen ion, inhibiting or killing bacteria, finding out the free radical generated by nano silver in electron spin resonance spectrum, observing the same result and finding out adding antioxidant N into the culture medium-The acetylcysteine can counteract the bactericidal effect of the nano-silver, namely, the free radicals generated by the nano-silver are related to the antibacterial property of the nano-silver. The bactericidal effect of nano silver at the initial stage of co-culture with bacteria is related to active oxygen generated by the nano silver, and the effective component for sterilization is proved to be hydroxyl radical. It is concluded that nano-silver can further oxidize the outer bacterial membrane by generating free radicals, thereby killing the bacteria.
2.4 inactivation of the dehydrogenase
The nano silver has extremely small particle size, can enter bacteria and be combined with sulfydryl of enzyme protein in thalli, so that enzymes containing sulfydryl groups lose activity, after the nano silver is treated, the activity of dehydrogenase in an escherichia coli respiratory chain is obviously reduced, and the higher the concentration of the nano silver is, the lower the enzyme activity is. Inhibition of respiratory enzyme activity may be associated with the production of reactive oxygen species. After the dehydrogenase is inactivated, the bacteria can not obtain the energy required by normal life activities, and can be subjected to the oxidative killing effect of active oxygen.
2.5 leakage of cell content
The observation of an electron microscope shows that the cell membrane of the thallus acted by the nano-silver is seriously damaged, small pits are formed on the cell wall, small holes are formed on the cell membrane, the permeability of the cell membrane is also damaged, and a large amount of reducing sugar, protein and K+Leakage from the cell body depletes the membrane potential and ATP. After the treatment of nano silver, the permeability of thallus cell membrane is changed, and a large amount of substances necessary for metabolism are leakedResulting in the death of the bacteria.
