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.

“…They allow indications to be made on the relative importance of forces, energies, and time scales. Although theoretical modeling of surface melting was performed in the past with ns-laser beams [ 45 , 46 , 47 ], time-resolved pump-probe imaging of laser-irradiated semiconductors [ 48 ] revealed an energy-dependent lifetime of the molten material in the range of 10 ns. This makes analytical calculations challenging in the case of fs-laser irradiation.…”

The formation and properties of laser-induced periodic surface structures (LIPSS) were investigated upon fs-laser irradiation of fused silica at different initial substrate temperatures, TS. For substrate heating between room temperature, TRT, and TS = 1200 °C, a continuous wave CO2 laser was used as the radiation source. The surface structures generated in the air environment at normal incidence with five successive fs-laser pulses (pulse duration, τ = 300 fs, laser wavelength, λ = 1025 nm, repetition frequency, frep = 1 kHz) were characterized by using optical microscopy, scanning electron microscopy, and 2D-Fourier transform analysis. The threshold fluence of fused silica was systematically investigated as a function of TS. It was shown that the threshold fluence for the formation of low-spatial frequency LIPSS (LSFL) decreases with increasing TS. The results reveal that the initial spatial period observed at TRT is notably increased by increasing TS, finally leading to the formation of supra-wavelength LIPSS. The findings are discussed in the framework of the electromagnetic interference theory, supplemented with an analysis based on thermo-convective instability occurring in the laser-induced molten layer. Our findings provide qualitative insights into the formation mechanisms of LIPSS, which allow improvements of the control of nanostructure formation to be made for corresponding applications of dielectric materials in the future.

“…14 In case of fused silica under normal incidence of linearly polarized light from a pulsed CO 2 laser, the fundamental mechanism of ripple formation is attributed to the generation of capillary waves owing to vapor recoil pressure and nonuniform removal of substance from the surface by evaporation. 15 Ripples have also been observed in photochemically deposited thin metal films. In photodeposited carbon films, the ripple generation is associated with irradiation near strong absorption bands of the parent and product compounds together with dipolar scattering.…”

Submicron ripples have been observed on a borosilicate glass surface when irradiated by a nanosecond Nd: yttritium–aluminum–garnet laser (10 ns, 1064 nm), using silica nanospheres. The ripples thus obtained do not satisfy Rayleigh’s diffraction condition in that (a) the ripple spacing is different from the value predicted by the classical model, (b) the spacing is independent of the incident angle, and (c) the orientation is not always perpendicular to the laser polarization. Also, the ripple characteristics are not dependent on the diameter of the spheres used and the ripples have almost the same periodicity irrespective of the experimental parameters. Photoionization followed by a self-organization process due to nonlinear absorption of the enhanced optical field between the spheres and glass sample is believed to be the primary reason for the creation of ripples on the glass substrate.
