CONTAMINATION 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 THE PROBLEM

dispersion FORGET 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: THE SOLUTION synthesis deposition activation

INTERDISCIPLINARITY The team is interdisciplinary and interinstitutional  Jožef Stefan Institute  Solid State Physics Dep. – Biophysics (Štrancar)  Solid State Physics Dep. – Chemical synthesis (Umek)  University of Ljubljana – Veterinary Faculty  Inst.Environ.Health&Anim.Hyg. – Food protection (Dobeic)  Inst.Microbiol.&Parasit. – Microbiology (Zdovc) THE FORCE

SELF-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 ! THE MARKET

SPIN-OFF – OPPORTUNITY ? SWOT 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
