IceTec Who are we?  A governmental laboratory reporting to the Ministry of Trade and Industry  We can participate in new development companies  Traditional industries have been the main customers  A group of 55 people in various fields  70% external income  30% gov. contribution l

Material and Product Testings  Product and material testing of metals and polymers.  NDT on metals  Failure analyses

“Surface” projects  Surfaces for the food industry  Biofilm formation  Together with Rf, Marel and Sæplast  FUNCOAT – Enhanced functionality of self cleaning and antibacterial surface coatings – NICe project  Glass or glased surfaces coated with titanium dioxide and silver  Superhydrophilic, radicals generated destroys organic matter on surface  Antobacterial (silver)  NANOREP  Scratch resistant coatings  Self cleaning/easy to clean traffic signs

Equipment for surface analyses  SEM – Scanning Eelctron Microscope, LEO Supra 25  AFM - Atomic Force Microscope, PSIA XE-100  Optical Profiling System – Solarius Viking CLA 400  Contact angle meter, KSV CAM 200  For surface energy calculations  Surface energy of bacteria and materials

SEM of bacteria on surfaces PP on PE

Photocatalytic self cleaning surfaces  Surface is coated with TiO 2 nanoparticles  Irradiation with sunlight makes the surface superhydrophilic  Radicals formed on the surfaces breaks down organic matter on the surface

Surface properties of bacteria  First step in bacterial adhesion is partly governed by surface properties/energy of bacteria and materials  Surface energy can be estimated from contact angle measurements of bacterial lawns and materials with different liquids  Pseudomonas putida (PP) is a hydrophobic bacteria  Explains why it is so widely found in fish processing plants  Adheres better to hydrophobic than hydrophilic materials  Listeria monocytogenes is a hydrophilic bacteria  Has lower tendency than PP to adhere to all materials
