“…To reach this purpose the fabrication process consists in the combination of ordered micro-machined structures with LIPSS, A c c e p t e d M a n u s c r i p t which have been demonstrated to be a very effective technique in order to generate controlled nanopatterns on the surface of bulk materials [25], polymers [26] or thin films [27], into hierarchical structures. The effect on the measured static APCA of these dual scale structures will be analyzed for different surface geometries.…”

“…For the generation of nanostructures, the most attractive approach is the fabrication of laser-induced periodic surface structures (LIPSS)2728: the variety of LIPSS that can be obtained in metallic surfaces, as well as their periodic nature and homogeneity, makes them an excellent option to study the influence of periodic nanopatterns on cell behavior. For strong absorbing materials, such as most metals, low-spatial-frequency LIPSS (LSFL), also called ripples, are observed with a period generally slightly smaller than the laser wavelength293031. Additionally, it is generally accepted that the irradiation with linearly polarized beams causes LIPSS that are perpendicularly aligned to the incident electric field (E-field) vector3233.…”

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 steel aiming at controlling cell adhesion and migration. The experimental results show that cells tend to attach and preferentially align to the laser-induced nanopatterns oriented in a specific direction. Accordingly, the laser-based fabrication method here described constitutes a simple, clean, and scalable technique which allows a precise control of the surface nano-patterning process and, subsequently, enables the control of cell adhesion, migration, and polarization. Moreover, since our surface-patterning approach does not involve any chemical treatments and is performed in a single step process, it could in principle be applied to most metallic materials.

“…Recently, femtosecond laser induced periodic surface structuring (LIPSSs) has proven its potential in metallic materials 18 , dielectrics 19 , polymers 20 and thin films 21 . Compared to traditional laser ablation techniques, femtosecond laser nanomachining delivers extreme peak irradiance with minimal thermal effects, offering the possibility of surface processing in open-air atmosphere and therefore avoiding expensive vacuum technologies, while being free of chemicals and relatively fast.…”

We demonstrate a rapid, accurate, and convenient method for tailoring the optical properties of diamond surfaces by employing laser induced periodic surface structuring (LIPSSs). The characteristics of the fabricated photonic surfaces were adjusted by tuning the laser wavelength, number of impinging pulses, angle of incidence and polarization state. Using Finite Difference Time Domain (FDTD) modeling, the optical transmissivity and bandwidth was calculated for each fabricated LIPSSs morphology. The highest transmission of ~99.5% was obtained in the near-IR for LIPSSs structures with aspect ratios of the order of ~0.65. The present technique enabled us to identify the main laser parameters involved in the machining process, and to control it with a high degree of accuracy in terms of structure periodicity, morphology and aspect ratio. We also demonstrate and study the conditions for fabricating spatially coherent nanostructures over large areas maintaining a high degree of nanostructure repeatability and optical performance. While our experimental demonstrations have been mainly focused on diamond anti-reflection coatings and gratings, the technique can be easily extended to other materials and applications, such as integrated photonic devices, high power diamond optics, or the construction of photonic surfaces with tailored characteristics in general.
