    <title language="eng">Femtosecond laser functionalized surfaces inspired by nature</title>
    <abstract language="eng">Nature has continuously inspired science when practical problems need to be solved in a functional and efficient way. The challenge for researchers usually consists in the transfer of such biological functionalities to diverse types of technical materials with the available processing technologies. In this regard, femtosecond laser-based approaches offer a large flexibility to modify virtually any material (metals, semiconductors and dielectrics), provide the ability to work under different environment conditions (air, vacuum or reactive atmospheres) and when combined with the proper optics, they offer exceptional spatial resolutions that could be used to mimic effectively very complex functionalities. In the particular case of surface processing, lasers have been proven feasible to functionalize materials by customizing its optical properties, chemical composition and surface morphology in a controllable way and in some cases at industrially relevant speeds. In this work, we present a selection of technical applications based on surface modifications in the form of laser-induced periodic surface structures (LIPSS) to tailor the material properties for utilization in optics, fluid transport, wetting control and tribology.</abstract>

    <title language="eng">Impact of Femtosecond Laser Treatment Accompanied with Anodization of Titanium Alloy on Fibroblast Cell Growth</title>
    <abstract language="eng">Herein, Ti6Al4V alloy is surface modified by femtosecond laser ablation. The microstructure image obtained by secondary electron microscopy reveals a combination of micrometer spikes or cones superimposed by nanoripples (laser‐induced periodic surface structures). To make the surface hydrophilic, anodization is performed resulting in further smoothness of microstructure and a final thickness of 35 ± 4 nm is estimated for oxide produced after anodization at 10 V (scan rate = 0.1 V s−1) versus standard hydrogen electrode. The obtained electrochemically active surface area (ECSA) is approximately 8 times larger compared with flat mirror polished Ti6Al4V surface. Combined chemical analysis by Pourbaix diagram and X‐ray photoelectron spectroscopy (XPS) analyses reveal that titanium and aluminum are passivating into TiO2 and Al2O3, but the dissolution of aluminum in the form of solvated ion is inevitable. Finally, cell seeding experiments on anodized and laser‐treated titanium alloy samples show that the growth of murine fibroblast cells is significantly suppressed due to unique surface texture of the laser‐treated and anodized titanium alloy sample.</abstract>

    <title language="eng">Applications on Surface Functionalization by Laser-Induced Periodic Surface Structures (LIPSS)</title>
    <abstract language="eng">In recent years, the understanding on the formation of laser-induced periodic surface structures (LIPSS) has led to an emerging variety of applications that modify the optical, mechanical and chemical properties of many materials. Such structures strongly depend on the used polarization and are formed usually after irradiation with ultrashort linearly polarized laser pulses. Some specific formation mechanisms to explain every situation are still to be uncovered, but the most accepted explanation relies on the interference of the incident laser beam with electromagnetic surface waves that propagate or scatter at the surface of the irradiated materials. This leads to an intensity modulation that is finally responsible for the selective ablation in the form of parallel structures with periodicities ranging from hundreds of nanometers up to some micrometers. The versatility when forming such structures is based on the high reproducibility with different wavelength, pulse duration and repetition rate laser sources, customized micro- and nanometric spatial resolutions and compatibility with industrially relevant processing speeds when combined with fast scanning devices. In this contribution, we review the latest applications in the rapidly emerging field of surface functionalization through LIPSS, including biomimetic functionalities on fluid transport, control of the wetting properties, specific optical responses in technical materials, improvement of tribological performance on metallic surfaces and bacterial and cell growth for medical devices among many others.</abstract>
