Abstract

Abstract A novel molecular scale device is described which is bactericidal, fungicidal and algicidal. The antipathogenic properties of the device are attributed to electron activity indigenous to diamagnetic semiconducting crystals of tetrasilver tetroxide (Ag 4 O 4 ) which contains two monovalent and two trivalent silver ions in each molecular crystal. When the crystals are activated with an oxidizing agent, they release electrons equivalent to 6.4×10 -19 watts per molecule which in effect electrocute pathogens. A multitude of these devices are effective at such low concentrations as 0.3 PPM where they can kill 100% of 100 K/cc Streptococcus faecalis, and E. coli colonies in three minutes meeting the ten-minute EPA criteria of 100% kills within ten minutes for swimming pool and hot-tub applications. The devices can be used in utilitarian bodies of water, such as municipal and industrial water reservoirs.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 64 words
A method for killing pathogens including bacteria, viruses and algae in utilitarian water bodies including the water of swimming pools, industrial cooling towers, hot tubs and drinking supply reservoirs, which comprises adding to the water a multitude of tetrasilver tetroxide molecular crystals which are capable of electrocuting said pathogens via an electron transfer mechanism involving their molecular structure in the presence of oxidizing agents.
Claim 2
Independent Claim 64 words
A method for killing pathogens including bacteria, viruses and algae in utilitarian water bodies including the water of swimming pools, industrial cooling towers, hot tubs and drinking supply reservoirs, which comprises adding to the water a multitude of tetrasilver tetroxide molecular crystals which are capable of electrocuting said pathogens via an electron transfer mechanism involving their molecular structure in the presence of oxidizing agents.
Claim 3
Dependent Claim 14 words
A method as claimed in claim 1 where the oxidizing agent is a persulfate.
Claim 4
Dependent Claim 25 words
A method as claimed in claim 1 where the concentration of the molecular crystals in the water is a maximum of one part per million.
Claim 5
Dependent Claim 25 words
A method as claimed in claim 2 where the concentration of the molecular crystals in the water is a maximum of one part per million.
