CONTAMINATIONCONTAMINATION

Listeria monocytogenes the most resistant among non-sporogenic bacteria (4˘C) cause meningitis (mort. 70%), sepsis (mort. 50%), neonatal

infections (mort. 80%), all very with delayed symptoms

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
