Hydrogen peroxide stabilised around silver

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…
