“…Beyond all described low pressure plasma technique, [74] non equilibrium atmospheric pressure plasma processes, in particular based on dielectric barrier discharges (DBDs) mechanism, can be applied in the frame of deposition of plasma polymers on biomaterials. Starting from the aerosol of the organic precursor, the plasma system reported in Figure 1 in [74] was used to deposit -CHO containing coatings from lactic acid (PPLA) and tetraethylene glycol dimethyl ether (PEO-like) of possible interest in biomedical applications as biodegradable and non-fouling polymers, respectively. For the first coating, a water DL lactic acid (LA) solution 90% v/v was atomized with N 2 or He by using a constant output atomizer.…”

Surface modification of dental implants is a key process in the production of these medical devices, and especially titanium implants used in the dental practice are commonly subjected to surface modification processes before their clinical use. A wide range of treatments, such as sand blasting, acid etching, plasma etching, plasma spray deposition, sputtering deposition and cathodic arc deposition, have been studied over the years in order to improve the performance of dental implants. Improving or accelerating the osseointegration process is usually the main goal of these surface processes, but the improvement of biocompatibility and the prevention of bacterial adhesion are also of considerable importance. In this review, we report on the research of the recent years in the field of surface treatments and coatings deposition for the improvement of dental implants performance, with a main focus on the osseointegration acceleration, the reduction of bacterial adhesion and the improvement of biocompatibility.

“…Plasma species is one of the key parameters, because it influences the amount of species obtained as well as the energy consumed during the treatment of materials, such as film deposition 7,8 , surface sterilization 9 , polymers surface treatment 9 , dental and skin treatments 10 . This knowledge is of utmost importance not only to obtain better results in respective treatments, but also to offer minimal risk to the operator and user when used in biomedical applications.…”

“…The wide varieties of ethylene oxide group containing precursors have been intensively studied to understand the retention properties of monomers, which are responsible for the protein repelling characteristic of the materials . A literature survey shows that ethylene glycol polymers were prepared by liquid deposition, liquid atomization, and vapor deposition by using the DBD technique. However, most of the studies reported so far are with helium (He) as a carrier gas to generate the plasma under the controlled environment by preventing air introduction in the plasma reactor.…”

A custom made non‐equilibrium atmospheric pressure argon plasma jet was developed for the deposition of PEG like coatings in open‐air for cell repellent applications. OES and electrical measurements were performed to characterize the discharge. The emission of the N2 (C3Πu–B3Πg) was followed in order to minimize the air entry in the plasma. Surface analyses were carried out on ap‐DEG coatings and the best retention of COC was obtained under mild plasma conditions. The ap‐DEG coatings were compared with typical LP deposited PEG like coatings. Less retention of COC and therefore less cell repellent properties were observed for ap‐DEG coatings as compared to those deposited at low pressure.
