“…[97] So far, just a few groups have studied LIPSS on basis of PIC-simulations. [98][99][100][101][102] Djouder et al simulated the irradiation of a copper target by linearly and circularly polarized fs-laser pulses (800 nm wavelength, 70 fs duration) at intensities up to 10 16 W cm −2 in a relativistic 2D-PIC scheme. [98,99] Their results indicate the early signature of LIPSS for the linearly polarized radiation already appearing during the laser pulse, featuring a sub-wavelength characteristics.…”

Surface nanostructuring enables the manipulation of many essential surface properties. With the recent rapid advancements in laser technology, a contactless large-area processing at rates of up to m 2 s −1 becomes feasible that allows new industrial applications in medicine, optics, tribology, biology, etc. On the other hand, the last two decades enable extremely successful and intense research in the field of so-called laser-induced periodic surface structures (LIPSS, ripples). Different types of these structures featuring periods of hundreds of nanometers only-far beyond the optical diffraction limit-up to several micrometers are easily manufactured in a single-step process and can be widely controlled by a proper choice of the laser processing conditions. From a theoretical point of view, however, a vivid and very controversial debate emerges, whether LIPSS originate from electromagnetic effects or are caused by matter reorganization. This article aims to close a gap in the available literature on LIPSS by reviewing the currently existent theories of LIPSS along with their numerical implementations and by providing a comparison and critical assessment of these approaches.

“…The crystal structure was not changed by laser treatment. However, the cell culture test proved that the micro‐patterns were beneficial to improve the biocompatibility of NiTi alloys: the growth of osteoblasts oriented along the grooves, a large amount of synapses and filopodia were formed due to ripples, holes and nanoparticles on the alloy surface, and the proliferation rate and alkaline phosphatase content of cells were increased after laser treatment 70…”

The surface nanoarchitecture provides spatially and temporally resolved stimuli response of the material, and offers defi ned control over the behavior of biomolecules and cells at the solid-liquid interface. Here, the focus is on metal-based systems that are interesting for biomedical applications. Intelligence of the surface is suggested to be achieved through its nanostructuring for stimuli responsive properties. Spatial and temporal cell performance at the surface, provided by the surface nanoarchitecture, offers advanced bio-applications of metal-based materials, such as implantation, lab-on-chip and organ-on-chip, biosensors, smart biomaterials and drug delivery systems. Spatial control is achieved by surface patterning. Temporal control is accessed through the application of stimuli responsive switchable surface chemistry, sensitive to external parameters: temperature, pH, light, electric and magnetic fi eld, ionic strength, surrounding medium (hydrogels in water), multi-trigger response, and response to products of the cell metabolism. The key issue is the prospect in the formation of self-regulating "intelligent" surface cell interactions: biomimetic of natural systems.

Ultrafast Laser‐Induced Sub‐100 nm Structures on Tungsten Surfaces: Stretched Liquid Dynamics Insights

The origin of high‐spatial‐frequency laser‐induced periodic surface structures, known as HSFLs, has always been a controversial topic. HSFLs of sub‐100 nm periodicity and sub‐20 nm amplitude are generated on tungsten by Ti:sapphire femtosecond laser irradiation under four different processing environments (ambient, air at 10 mbar, Ar at 10 mbar, and vacuum at 10−7 mbar). The topography and subtopography analysis together with two‐temperature model–molecular dynamics simulations reveal that HSFLs formation originates from laser‐induced thermal stresses, implying both surface tension and tensile forces are involved. The experimental observation of subsurface cavitation confirms a hydrodynamics‐based origin for these nanostructures.
