“…The preferential attachment of osteoprogenitor cells has been investigated on Mylar films containing grooves of varying spacing, width, and depth [137]. The grooves are carved into the surface of the Mylar film using a KrF excimer laser beam that is coupled with a metal photomask that does not touch the surface of the polymer film.…”

“…Surface topology is known to play an important role in cell adhesion to surfaces of biomaterials, various kinds of implant surface texturing methods, including the use of lasers, are used to increase cell attachment and subsequent proliferation [5][6][7]. However, the techniques commonly used to create surface textures in commercial applications are mechanical (machining, sand-blasting) or chemical methods (such as acid etching, oxidation), all of which lack the spatial selectivity that laser-based texturing can offer.…”

Abstract:We propose and demonstrate the use of short pulsed fiber lasers in surface texturing using MHz-repetition-rate, microjoule-and sub-microjoule-energy pulses. Texturing of titanium-based (Ti6Al4V) dental implant surfaces is achieved using femtosecond, picosecond and (for comparison) nanosecond pulses with the aim of controlling attachment of human cells onto the surface. Femtosecond and picosecond pulses yield similar results in the creation of micron-scale textures with greatly reduced or no thermal heat effects, whereas nanosecond pulses result in strong thermal effects. Various surface textures are created with excellent uniformity and repeatability on a desired portion of the surface. The effects of the surface texturing on the attachment and proliferation of cells are characterized under cell culture conditions. Our data indicate that picosecond-pulsed laser modification can be utilized effectively in low-cost laser surface engineering of medical implants, where different areas on the surface can be made cell-attachment friendly or hostile through the use of different patterns. 192-203 (1997) Lett. 17, 733-737 (2004). 25.

“…In both cases, alternative approaches to complex guidance cues have been explored. On artificial substrates, such as silicon wafers, nerves have been directed by topographically structured surfaces (10) or by selectively patterning the substrate with materials that act as adhesives for nerves (11,12). Damaging tensions, however, often rip apart the neuronal structures formed on the substrate due to the tendency of axons to straighten and stiffen with time.…”
