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

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.
