abstract = "Hybrid diamond-like carbon (DLC) with incorporated titanium
dioxide (TiO2) nanoparticle coatings have low friction
coefficient, high wear resistance, high hardness,
biocompatibility, and high chemical stability. They could be
employed to modify biomedical alloys surfaces for numerous
applications in biomedical engineering. Here we investigate for
the first time the in vivo inflammatory process of DLC coatings
with incorporated TiO2 nanoparticles. TiO2-DLC films were grown on
AISI 316 stainless-steel substrates using plasma-enhanced chemical
vapor deposition. The coated substrates were implanted in CF1 mice
peritoneum. The in vivo cytotoxicity and biocompatibility of the
samples were analyzed from macrophage lavage. Analysis in the
first weeks after implantation could be helpful to evaluate the
acute cytotoxicity generated after a possible inflammatory
process. The in vivo results showed no inflammatory process. A
significant increase in nitric oxide production on the uncoated
substrates was confirmed through cytometry, and the coated
substrates demonstrated biocompatibility. The presence of TiO2
nanoparticles enhanced the wound healing activity, due to their
astringent and antimicrobial properties. DLC and TiO2-DLC coatings
were considered biocompatible, and the presence of TiO2
nanoparticles reduced the inflammatory reactions, increasing DLC
biocompatibility.",
