Ag

Hydrogen peroxide stabilised around silver

Silver “radiation”

1. The Silver Effect1. The Silver Effect

The silver weakens the outer defenses of the micro-organism

Ag

Increase in kinetic energy due to presence of micro-organism

Ag

Hydrogen peroxide pull away and head toward micro-organism

Huwa-SanHuwa-San TR50 TR50The combined effectThe combined effect

The presence of the Silver has weakened outer defense mechanism. This in combination with the increased energy of the hydrogen peroxide leads to:

Micro-organism oxidised DNA destroyed

into the environment

They loose their kinetic energy…

… and return to await their next target…
