Surface micro- and nano-texturing of stainless steel by femtosecond laser for the control of cell migration

Abstract: The precise control over the interaction between cells and the surface of materials plays a crucial role in optimizing the integration of implanted biomaterials. In this regard, material surface with controlled topographic features at the micro- and nano-scales has been proved to affect the overall cell behavior and therefore the final osseointegration of implants. Within this context, femtosecond (fs) laser micro/nano machining technology was used in this work to modify the surface structure of stainless stee… Show more

“…The results can be explained by differences in the non-linear absorption behavior and viscosity of the investigated glasses. Our findings will facilitate the tailored fabrication of LIPSS-based surface structures on different technical relevant glasses and are of particular interest for sophisticated applications in plasmonics [ 47 ], microfluidic devices [ 48 ], control of cell behavior through patterned surfaces [ 49 , 50 ], and the engineering of surfaces with specific wetting properties [ 51 , 52 ].…”

“…Even if pure titanium or its alloys are often practiced in medical sectors due to good integration into the human body, in particular cases, 316L stainless steel is used for certain applications such as in dental crowns, brides or implants, orthopaedic prostheses and bone tissue engineering scaffolds [6,18]. This observation was taken into account for manufacturing cases.…”

“…Another important application in this area of research is the control and manipulation of cell adhesion to laser‐treated biomaterial interfaces. Laser structuring of biomaterial surfaces creates micrometer‐scale or sub‐micrometer‐scale features that influence surface wettability, roughness, and hydrophobicity . These surface characteristics modulate how cells sense the biomaterial surface through focal adhesions and lamellipodial/filopodial extensions.…”
