To address one of the serious problems associated with permanent implants, namely bacterial
infections, novel organic/inorganic coatings containing zinc oxide nanoparticles (nZnO) are proposed.
Coatings were obtained by electrophoretic deposition (EPD) on stainless steel 316L. Different
deposition conditions namely: deposition times in the range 60-300 s and applied voltage in the
range 5-30 V as well as developing a layered coating approach were studied. Antibacterial tests
against gram-negative Staphylococcus aureus and gram-positive Salmonella enteric bacteria
confirmed the activity of nZnO to prevent bacterial growth. Coatings composition and morphology
were analyzed by thermogravimetric analysis, Fourier transform infrared spectroscopy, scanning
electron microscopy and energy dispersive X-ray spectroscopy. Moreover, the corrosion resistance
was analyzed by evaluation of the polarization curves in DMEM at 37°C, and it was found that
coatings containing nZnO increased the corrosion resistance compared to the bare substrate.
Considering all results, the newly developed coatings represent a suitable alternative for the surface
modification of metallic implants.

In the area of orthopedic and dental implants, designed for long-term use, increasing attention is
being dedicated to the durability of such biomaterials [1, 2]. Scientific research and development are
mainly aimed at increasing the surface biocompatibility. To replace hard tissues metals (titanium
alloys, cobalt-chromium alloys or stainless steel) are the materials of choice, because of their
superior mechanical properties, corrosion and wear resistance as well as biotolerance [2–4].
However, a factor that may lead to implant failure is surgery related infection. Complications caused
by infections occur in the 1-2 % of total hip replacements procedures [5, 6]. The increasing number of
joint replacements being performed means that the absolute number of such infections is significant,
increasingly posing substantial costs to the healthcare system . The most common pathogen
following orthopedic procedures is Staphylococcus aureus [5, 6]. Therefore, the demand for
biomaterials with antibacterial properties is increasing [7, 8].
