FORGET ANTIBIOTICS, FIGHT WITH RADICALSFORGET ANTIBIOTICS, FIGHT WITH RADICALS
To keep surface clean:
1. Stably deposit nanomaterials on a surface and
2. Excite nanomaterials to produce the radicals and shut down the bacterial energy transmission and prevent bacterial growth
The following phenomena are optimized against AB activity:

SELF-CLEANING SURFACESSELF-CLEANING SURFACES
Surface-deposited nanomaterials feature controlable release-free protection in
– food storage / processing / cathering
– health care processes
The materials can substantially reduce the disinfenctants use and eliminate the need for any antibiotics !T

THREATS
• dissemination can help other R&D groups to establish competitive company
• different solutions/implementations confuse possible customers
• lack of legislation / administrative support can delay spin-off creation
OPPURTUNITIES
• substantial market identified as well as the need for such product (European Veterinary Administration)
• mechanisms avoiding usage of antibiotics or release of the nanoparticles in the environment
WEAKNESSES
• product tested only in laboratory• deposition technology still not
completely established• large production defined but not
tested
STRENGTHS
• highly motivated team• processes identified• mechanisms understood• research methods mastered
