Nano-sized silver powders coated with sodium oleate (NanoAg@C18) was prepared by a simple wet chemical route and characterized
by FT-IR, DTA-TG, TEM, SAED and EDS. The main objective of this research was to successfully employ the NanoAg@C18
for the inhibition of bacterial and fungal biofilms in vitro development on catheter sections with a film-coated surface. The lower value of
the relative microbial biomass formed on the surface of the modified prosthetic devices demonstrates the anti-biofilm efficiency of the
NanoAg@C18 coating and the potential use of this nanosytem for obtaining improved medical devices.
