ANTIMICROBIAL
TECHNOLOGY
Antimicrobial technology
Non-migrating & durable technology with a
broad spectrum of activity against microbes
No migration to the skin nor to the environment
Quick and easy to verify
Outstanding safety and registration profile

Benefits of the BI-OME technology
Long-lasting freshness
Eliminates the smells created by yeast,
fungus and bacteria in the product
Controls or eliminates microbial
staining of the treated article
Antimicrobial agents - Mode of action
Conventional organic and inorganic active substances
Migration
from substrate to bacteria
for antimicrobial action
No migration
mechanical process
for antimicrobial action
Unconventional organo functional silane active substances
Diffuse from the substrate to the microbe:
• Leach or migrate out of the substrate into the
environment
• Are consumed by micro-organisms
• Chemically interrupt (poison) the cell
• May cause adaptive micro-organisms
• Leach out in contact with water or humid
conditions
Migrating antimicrobials
Migrating antimicrobials
Zone of inhibition in agar diffusion tests
Are bounded to the substrate and require a contact by the microbe:
Are bonded to the product surface
Are not consumed by micro-organisms
Mechanically interrupts (stabs) the cell wall
Remain functional for the life of the product
Will not cause adaptive micro-organisms
Non migrating antimicrobials
Organo functional silanes
N-halamines
Grafting by irradiation
Non migrating antimicrobials
Antimicrobial active substances that do not migrate in order
to be active are for example:
No zone of inhibition => no sub lethal concentration => no adaptation
The BI-OME technology: disruption
Cell disruption mechanism
Disruption
Each micro-organism will come into contact
with approximately 25.000 “swords” at the
surface.

General
Overview of the most important antimicrobial tests world wide
SANITIZED Standard Tests are effected according to the Swiss Norm (SN 195 920 and SN 195 921). Other tests have to be agreed upon.
