“…The protective metal oxide thin film is stable and can determine the corrosion behavior and tissue biocompatibility of the implant. Considering different oxides used, zinc oxide (ZnO) offers a number of advantages such as low toxicity, high resistance to corrosion, biocompatibility, piezoelectricity and considerable antibacterial activity [15][16][17]. Furthermore, zinc (Zn) is present as an essential trace element in more than 300 proteins and is involved in several cellular processes, being a common ion present in many organisms [18].…”

Important clinical concerns in orthopedics and dental implantology are associated with a significant release of titanium (Ti) metal ions and debris due to the low corrosion resistance of this material. Chemical modifications on Ti surfaces have been performed in order to minimize effects of corrosion. In this contribution, zinc oxide (ZnO) thin films were deposited onto Ti surfaces and functionalized with four different organic bifunctional molecules in order to increase the corrosion resistance. SEM and XPS indicated the formation of nanostructured ZnO thin film with hydroxyl groups available for covalent functionalization. The adhesion mechanism analyzed by XPS suggest that the attachment on ZnO occurs by carboxylic acid, silane, thiol and hydroxyl groups for 4aminophenylpropionic acid (APPA), 3-aminopropyltrimetoxysilane (APTMS), 3-mercaptopropionic acid (MPA), and polyethylene glycol (PEG) molecules. Electrochemical analysis for the functionalized ZnO specimens with APPA showed noble open circuit potentials (−0.2 V) and significant decrease in the corrosion current density (5.3 × 10 −7 A/cm 2) when compared to the values obtained for pristine Ti (−0.56 V and 2.3 × 10 −6 A/cm 2), indicating a promising material for applications in biomedical fields.

In this research, ZnO/ZnS core/shell nanostructures were grown by electro-hydrothermal methods on titanium substrates. To optimize the growth of the nanostructures, the ZnO seed layer electro-deposition time was adjusted to modify the surface of the nanostructure. Multiple material characterizations were performed to examine the surface morphologies and material properties of the nanostructures. Results indicate that ZnO/ZnS nanostructures with ZnO deposition time of 5 sec had well-grown ZnO nanorods and high-quality ZnS nanoparticles for ZnO/ZnS core shell structures. ZnO/ZnS nanostructures on titanium substrates show promising for future development of titanium substrate-based biomedical and optoelectronic devices in the future.

“…As it was reported, ZnO has been added to the coating bath to strengthen the corrosion resistance of a zinc phosphate-based coating on the AZ91D magnesium alloy [23,24]. Moreover, ZnO offers several advantages such as non-toxicity, biocompatibility, and excellent antibacterial activity; in addition, it is abundance in nature [22,[25][26][27]. The great potential of nano-structured ZnO in biosensor [28,29], bio-imaging, and drug delivery led to its biomedical [30] applications are being widely investigated.…”
