“…In particular, the ion deposition with simultaneous ion implantation (plasma-based ion implantation and deposition: PBII-D) is desirable for efficient processing and has an advantage over conventional methods 25) . Recently, several researchers have carried out surface modification using fluorine (F) ion and found it to be a useful means of inhibiting bacterial adhesion 17,18,20,22,26) . In our previous study, stainless steel implanted with F ion by PBII could provide antibacterial activity and inhibit bacterial adhesion 20) .…”

“…In the case of metallic materials, physical modifications are mainly chosen. For instance, several studies have indicated that surface modifications, such as ion implantation [17][18][19][20][21] and film coating 17,22) , are effective in reducing bacterial infection. Plasma-based ion implantation (PBII) in particular, is a promising method for the surface modification of threedimensional materials 23) .…”

The aims of this study were to modify dental device surface with fluorine and silver and to examine the effectiveness of this new surface modification method. Stainless steel plates were modified by plasma-based fluorine and silver ion implantation-deposition method. The surface characteristics and brushing abrasion resistance were evaluated by XPS, contact angle and brushing abrasion test. XPS spectra of modified specimens showed the peaks of fluoride and silver. These peaks were detected even after brushing abrasion test. Water contact angle significantly increased due to implantation-deposition of both fluorine and silver ions. Moreover, the contact angle of the modified specimen was significantly higher than that of fluorine only deposited specimen with the same number of brushing strokes. This study indicates that this new surface modification method of fluorine and silver ion implantationdeposition improved the brushing abrasion resistance and hydrophobic property making it a potential antimicrobial device.

“…However, the different coatings also produced a different level of roughness on the surface -with a strong correlation found between the number of adhering cells and the surface roughness. Fluorinated DLC has also been found to have antibiological properties in regards to decreasing surface adhesion as well as increasing the removability of adhered cells [128,129]. This became more pronounced as the proportion of F content was increased in the coating, as it was found to reduce the surface energy of the surface [128].…”

Abstract.There are three different factors that can affect adhesion: the process fluid, the processing conditions and the surface of the processing equipment. Of these three factors, the surface properties of the processing equipment are the factor that offers the greatest opportunity for manipulation. The two key surface properties that have been identified to reduce adhesion are the surface energy and the surface topography. The surface energy of a material determines its degree of wettability and, a surface's affinity for water. In previous studies the surface energy of materials have been leveraged in order to create a surface with reduced levels of fouling through surface modification or the addition of polymer coatings with varying degrees of hydrophobicity. In addition, the topography of surfaces has been modified to reduce the level of particle adhesion. These modifications involve creating either a structured or random porous microstructure on the surface. Additional methods identified to reduce fouling include the application of liquid infused porous surfaces at low shear conditions and the use of non-contact heating through techniques such as microwave processing.

“…To the best of our knowledge, no reports have been found in the literature on the fabrication or applications of ordered hydrocarbon or fluorinated hydrocarbon nanodots formation using PECVD utilizing NSL mask. However, PECVD grown ordered hydrocarbon or fluorinated hydrocarbon nanostructured films produced though NSL mask might have great potential in several areas such as in superhydrophobic coatings [21] and [22], antibacterial applications [23], interlayer dielectrics because of its low dielectric constant [24], nanocrystalline diamond resonator array for the application of RF signal processing [25], etc. [26].…”
