Definitions
- Antiviral surfaces comprising polyoxometalates and
- the invention relates to antiviral compositions comprising polyoxometalates and zinc molybdate for combating viruses and in particular corona viruses.
- the surfaces of objects are treated with antiviral agents or equipped with antiviral properties.
- Disinfectants among other things, are used to combat the virus.
- a major disadvantage of using disinfectants is the development of resistance and cross-resistance among the microorganisms that are also on the surfaces to be disinfected. Therefore, there is an increasing search for alternatives to combat microorganisms effectively and to prevent microorganisms from colonizing surfaces.
- One possibility is the use of metals and metal compounds. Because of their good antiviral effect, silver and copper in particular are frequently used.
- the elemental metal is provided in a form with the largest possible surface area in order to achieve high activity.
- Nanoparticles, foamed metal or nanoparticles fixed on a carrier are particularly suitable here.
- a second variant provides for the provision of soluble metal salts, which are incorporated, for example, in zeolites or directly in a composite material.
- the disadvantage is that the precious metals or precious metal ions mentioned are comparatively expensive and are also almost completely inactivated by sulfur-containing compounds or high electrolyte concentrations.
- polyoxometalates as antiviral agents has also been discussed. Among other things, the effectiveness of polyoxometalates with titanium doping in a surface against viruses was described. Titanium is used to generate electrostatic potentials and free radical activity such as oxygen radicals to enhance polyoxometalate activity.
- Polyoxotungstates are known for their anti-influenza virus activity.
- the object of the present invention is to provide improved antiviral compositions and/or surfaces containing polyoxometalates.
- the object according to the invention is achieved by adding zinc molybdate (ZnMo0 4 ) to the polyoxometalates or by providing mixtures comprising zinc molybdate and polyoxometalates.
- Polyoxometalates in the sense of the invention are a group of substances which have polyatomic anions. These are made up of three or more transition metal oxyanions and compressed via oxygen atoms. Polyoxometalates can form a large closed three-dimensional network.
- the metal atoms are usually transition metal atoms from groups V or VI of the periodic table in high oxidation numbers, ie the electron configurations d° or d 1 .
- Examples are vanadium (V), niobium (V), tantalum (V), molybdenum (VI) and tungsten (VI).
- polyoxometalates As biocides generated in situ, polyoxometalates have an antibacterial effect against numerous pathogenic microorganisms such as hepatitis B, hepatitis C, enveloped viruses such as herpes viruses and corona viruses as well as a large number of bacterial microorganisms, regardless of their resistance to antibiotics, fungi including mold and algae.
- pathogenic microorganisms such as hepatitis B, hepatitis C, enveloped viruses such as herpes viruses and corona viruses as well as a large number of bacterial microorganisms, regardless of their resistance to antibiotics, fungi including mold and algae.
- the broad antimicrobial effectiveness of the polyoxometalates is based on the synergistic effectiveness of 3 mechanisms, which leads to the rapid elimination of viral and bacterial microorganisms and fungi in situ on surfaces.
- Electrostatic surface charge also exhibits antibacterial and antiviral properties. Electronegatively charged microorganisms are attracted to the positively electrostatically charged surfaces and rupture within minutes after contact with the surface. This has been documented for bacterial microorganisms using laser scanning microscopy.
- These polyoxometalates can either be incorporated into a polymer surface or into a transparent coating, e.g. B. liquid polyurethane, liquid silicone and other coating materials such as paints are introduced, which preferably dry within an hour.
- Various coating materials have already been developed to take polyoxometalates. The duration of effectiveness is at least 10 years and has been confirmed by appropriate studies. The effectiveness is not affected by surfactants, alcohol and water.
- the maintenance of the electrostatic potential, and thus the antibacterial, in particular antiviral, effect is enhanced by the additional addition of zinc molybdate (ZnMoC).
- Zinc molybdate usually has a tetragonal crystal structure. It is insoluble in water and therefore practically non-toxic. In addition to the well-known tetragonal crystal structure in a triclinic crystal structure, zinc molybdate has a significantly higher antiviral effectiveness. The effect is significantly improved compared to that of tetragonal zinc molybdate with the same grain size.
- Triclinic zinc molybdate can be obtained by ultrasonically assisted reaction of a solution of one or more water-soluble molybdates with a solution of one or more water-soluble zinc(II) salts.
- the water-insoluble zinc molybdate formed during the reaction of the educt salts precipitates in the form of triclinic crystals.
- the grain size of the triclinic crystals can vary.
- a particularly good antiviral activity was according to the invention for zinc molybdate in the form of particles with a triclinic crystal structure and a average particle size in the range of 0.10 gm to 5.0 gm, preferably between
- the use of zinc molybdate in the mixture according to the invention is therefore preferred for ZnMoC in the form of particles with a triclinic crystal structure and an average grain size between 0.1 ⁇ m and 5.0 ⁇ m, preferably 0.25 ⁇ m and 5.0 ⁇ m.
- the triclinic zinc molybdate has a particle size in the range from 0.15 gm to ⁇ 1 gm and more preferably in the range from 0.20 gm to 0.8 gm.
- Triclinic zinc molybdate is non-toxic to humans and animals and therefore has excellent biocompatibility. It can be produced comparatively cheaply and shows a strong antiviral effect even in small amounts. In addition, zinc molybdate is not inactivated by sulphur-containing compounds or by a high concentration of electrolytes, but retains its effectiveness.
- Zinc molybdate with a triclinic crystal structure and the particle size indicated above shows high antiviral activity against a broad spectrum of microorganisms, including algae, fungi and enveloped viruses, as well as gram-positive and gram-negative microorganisms regardless of their antibiotic resistance.
- Microorganisms against which triclinic zinc molybdate is effective include Lactobacillus acidophilus, Pseudomonas, e.g. B.
- P. aeruginosa salmonella, e.g. B. Saureus, E. coli, Candida Spp, C. albicans, C. glabrata and C. tropicalis, Legionella, Listeria; viruses such as B. influenza, Ebstein Barr virus, rotavirus and norovirus; and Aspergillus niger, fumigatus and flavus.

It has been found that with a triclinic crystal structure of zinc molybdate with an average grain size in the micrometer range, excellent antiviral effectiveness is achieved, so that the risks associated with nanoparticles can be avoided. In the sub-micron range, zinc molybdate with a triclinic crystal structure is particularly effective.
