onochemistry is our deposition method for imparting unique properties to the desired substrates. It was applied frst to coat a
large variety of textiles (cotton, polyester, nylon wool and more) with anti-bacterial Nanoparticles (NPs). Excellent adherence
to the textiles was demonstrated in withstanding 65 washing cycles in Hospital washing machines. In the current presentation its
power will be demonstrated in the deposition of antimicrobial NPs on medical devices such as catheters, contact lenses, cochlear
electrodes, and silicon-implants. It was also deposited on artifcial teeth by the sonic irradiation and avoided the formation of
bioflm of

experiments were conducted. The frst experiment conducted in Israel where 5 coated and 5 uncoated silicon catheters were
installed in rabbits (
Figure 1
) that were hanged during the 7 days of the experiment. The second was done in Synovo, Tubingen
where 15 coated and 15 uncoated catheters were inserted in the rabbits which were free to run around. In both cases the coated
catheters have avoided the formation of bioflm on the catheters in comparison with the appearance of urine contamination after
day 4. Good results were obtained in all the above mentioned medical devices.
