    Abstract

    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.

    1. Introduction

    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 [5]. The most common pathogen

    following orthopedic procedures is Staphylococcus aureus [5, 6]. Therefore, the demand for

    biomaterials with antibacterial properties is increasing [7, 8].
