“…Remarkably, dopants give a possibility to manufacture coatings that have high antibacterial activity and favorable interaction with human cells. DLC coatings contain both Ag and Si (1.65 at % Si and 2.09 at % Ag) are biocompatible and capable to reduce the viability of the adhered bacteria up to 50%, while the non-doped DLC films have no bactericidal effect [ 168 ]. Similarly, the existence of nitrogen in DLC films may enhance the antibacterial performance.…”

Swift developments in nanotechnology have prominently encouraged innovative discoveries across many fields. Carbon-based nanomaterials have emerged as promising platforms for a broad range of applications due to their unique mechanical, electronic, and biological properties. Carbon nanostructures (CNSs) such as fullerene, carbon nanotubes (CNTs), graphene and diamond-like carbon (DLC) have been demonstrated to have potent broad-spectrum antibacterial activities toward pathogens. In order to ensure the safe and effective integration of these structures as antibacterial agents into biomaterials, the specific mechanisms that govern the antibacterial activity of CNSs need to be understood, yet it is challenging to decouple individual and synergistic contributions of physical, chemical and electrical effects of CNSs on cells. In this article, recent progress in this area is reviewed, with a focus on the interaction between different families of carbon nanostructures and microorganisms to evaluate their bactericidal performance.

“…DLC is an excellent base coating to be alloyed with different elements. Incorporation of selected elements into DLC has emerged as an innovative approach to add unique functional properties to DLC coatings, thus opening up a range of new potential applications for biomedical devices (Dearnaley and Arps 2005;Marciano et al 2010;Maegawa et al 2016;Swiatek et al 2016). The incorporation of Si, F, N or Ag into DLC reduced bacterial adhesion (Liu et al 2008;Marciano et al 2010;Su et al 2010;Cloutier et al 2016).…”

A range of titanium doped diamond-like carbon (Ti-DLC) coatings with different Ti contents were prepared on stainless steel substrates using a plasma-enhanced chemical vapour deposition technique. It was found that both the electron donor surface energy and the surface roughness of the Ti-DLC coatings increased with increasing Ti contents in the coatings. Bacterial adhesion to the coatings was evaluated against Escherichia coli WT F1693 and Pseudomonas aeruginosa ATCC 33347. The experimental data showed that bacterial adhesion decreased with the increases of the Ti content, the electron donor surface energy and surface roughness of the coatings, while the bacterial removal percentage increased with the increases of these parameters. The Ti-DLC coatings reduced bacterial attachment by up to 75% and increased bacterial detachment from 15 to 45%, compared with stainless steel control.

The nanocomposite films Ag/a‐C:H were prepared by vacuum‐based method which combines deposition of Ag nanoparticles by means of gas aggregation source (GAS) and PECVD deposition of a‐C:H matrix. The matrix was deposited in a mixture of Ar and n‐hexane on the substrates placed on the powered RF electrode facing the beam of Ag NPs from the GAS. Anisotropic plasma etching was used to increase Ag concentration on the surface of the coating. The influence of three types of plasma on the chemical composition of the coatings and on the size of Ag nanoparticles is described. It is shown that the best etching selectivity and thus the highest Ag surface concentration was reached in case of etching of grounded samples in low pressure oxygen plasma. This treatment enhances the short term antibacterial efficiency of produced coatings.
