“…This is coherent with earlier studies, where femtosecond laser irradiation is used to treat stainless steel surfaces [12][13][14]. Depending on the experimental conditions, some of them have managed to achieve super-hydrophobic surfaces.…”

In the present work a novel method to improve the surface properties of stainless steel is presented and discussed. The method, based on the use of a high repetition rate femtosecond Yb fibre laser, permits generation of highly reproducible, robust, uniform and periodic nanoscale structures over a large surface area. The technique is characterized by high productivity, which, in its most simple form, does not require special environmental conditioning. Surface morphology is scrutinized through SEM and AFM analyses and wettability behaviour is investigated by means of the sessile drop method using distilled–deionized water. It is shown that optimization of process parameters promotes anisotropic wetting behaviour of the material surface

“…For example, laser treatment has been employed in a number of studies to modify the surface of SS. Using femtosecond laser, Oberringer et al [30] were able to engineer a SS surface that reduced the differentiation of myofibroblasts, being this beneficial in the prevention of restenosis. Micro-and nanofeatures produced by this method had no effect on proliferation of endothelial cells (ECs), but the effect of other interfering factors, such as hydrophilicity and oxygen content, were not fully studied.…”

Stainless steel (SS) has been widely used as a material for fabricating cardiovascular stents/valves, orthopedic prosthesis, and other devices and implants used in biomedicine due to its malleability and resistance to corrosion and fatigue. Despite its good mechanical properties, SS (as other metals) lacks biofunctionality. To be successfully used as a biomaterial, SS must be made resistant to the biological environment by increasing its anti-fouling properties, preventing biofilm formation (passive surface modification), and imparting functionality for eluting a specific drug or capturing selected cells (active surface modification); these features depend on the final application. Various physico-chemical techniques, including plasma vapor deposition, electrochemical treatment, and attachment of different linkers that add functional groups, are used to obtain SS with increased corrosion resistance, improved osseointegration capabilities, added hemocompatibility, and enhanced antibacterial properties. Existing literature on this topic is extensive and has not been covered in an integrated way in previous reviews. This review aims to fill this gap, by surveying the literature on SS surface modification methods, as well as modification routes tailored for specific biomedical applications.

“…It is demonstrated that the osteoblastic cells tend to attach preferentially to blasted or plasma sprayed surfaces with a rougher topography, while the fibroblast cells favor smooth surfaces [14]. From a systematic review of these studies it is indicated that most research focuses on surface modifications of pure Ti or Ti-based alloy, and there are relatively fewer reports on the treatments of stainless steel [15]. A typical study was performed by McLucas et al in 2006 [16], who investigated the interaction between endothelial cells and stainless steel with three different surface treatments (as received, polished and sandblasted with the surface roughness value of 95.8 nm, 40.8 nm, and 671.8 nm, respectively).…”
