Claims
What is claimed is:
1. A composition of silver in water comprising a total concentration
of silver of between about 5 and 40 parts per million, said silver in
the form of colloidal silver particles having an interior of elemental
silver and a surface of silver oxide, wherein a majority of the
colloidal silver particles have a maximum diameter less than 0.015
micrometers, wherein a majority of the colloidal silver particles have
a minimum diameter greater than 0.005 micrometers, and wherein the
composition exibits antimicrobial properties.
2. The composition according to claim 1, wherein at least 75% of the
colloidal particles have diameters between 0.005 micrometers and 0.015
micrometers.
3. The composition according to claim 2, wherein at least 90% of the
colloidal particles have diameters between 0.005 micrometers and 0.015
micrometers.
4. The composition according to claim 3, wherein at least 95% of the
colloidal particles have diameters between 0.005 micrometers and 0.015
micrometers.
5. The composition according to claim 1, wherein the colloidal
particles have an average diameter of about 0.0106 micrometers.
6. The composition according to claim 1 further comprising hydrogen
peroxide.
7. The composition according to claim 6, wherein the hydrogen peroxide
concentration is between about 1% wght/v and about 3.0% wght/v.
8. The composition according to claim 1, wherein the composition
exhibits antimicrobial properties against microbes selected from the
group consisting of Bacillus anthracis, Bacillus subtilis, Candida
albicans, Mycobacteria bovis, Mycobacteria tuberculosis, Pseudomonas
aeruginosa, Salmonella choleraesius, Staphylococcus aureus,
Trichomonas vaginalis, and Yersinia pestis.
9. The composition according to claim 8, wherein Staphylococcus aureus
is a methicillin-resistant strain.
10. The composition according to claim 1, wherein the composition
exhibits antimicrobial properties against microbes associated with
diseases selected from the group consisting of malaria, fungal
infections of the skin, bacterial infections of the skin, vaginal
infections, urinary tract infections, tonsillitis, pelvic inflammatory
disease, pharyngitis, gonorrhea, conjunctivitis, otitis, respiratory
tract infections, and nasal infections.
11. The composition according to claim 1, wherein the antimicrobial
properties are antiviral properties.
12. The composition according to claim 11, wherein the antiviral
properties are exhibited against a virus selected from the group
consisting of human immunodeficiency virus and hepatitis B virus.
13. The composition according to claim 11, wherein the antiviral
properties include inhibition of viral DNA polymerase.
14. The composition according to claim 11, wherein the antiviral
properties include inhibition of viral reverse transcriptase.
