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

forget antibiotics fight with radicals
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

dispersion

deposition

activation

interdisciplinar i ty
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
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 disinfenctantsuse and eliminate the need for any antibiotics !

THE MARKET

slide5

SPIN-OFF – OPPORTUNITY ?

STRENGTHS

  • highly motivated team
  • processes identified
  • mechanisms understood
  • research methods mastered

WEAKNESSES

  • product tested only in laboratory
  • deposition technology still not completely established
  • large production defined but not tested

SWOT

OPPURTUNITIES

  • substantial market identified as well as the need for such product (European Veterinary Administration)
  • mechanisms avoiding usage of antibiotics or release of the nanoparticlesin the environment

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
