In particular, over the last decade, our group dedicated itself to the study of preparing nanostructures and the nanostructuring of solid surfaces,especially using plasma treatment, laser irradiation and thermal modification. Up to this day,much effort has been put into producing smart materials with extraordinary properties usable in a broad range of technological applications. In the last two decades, it has been demonstrated that the production of materials with completely new properties does not onlydepend on its chemical composition, but also on dimensions associated withbuilding blocks of conventionally known materials. Primarily, our group dealt with structures which could find applications in tissue engineering (cell adhesion and proliferation improvement), electronics (adhesion improvement between polymer or glass substrate and metal coatings) and optoelectronics (optical lattice). In this chapter we are going to focus on the preparation and characterization of nanostructures prepared on polymer or glass surfaces. These materials were modified by plasma and laser treatments and were subsequently subjected to various analytical methods to reveal: chemical structure (FTIR, UV-Vis, XPS, AAS, RBS and Raman spectroscopy), electrical properties (sheet resistance, Van der Pauw method), optical properties (ellipsometry), ablation of layer (gravimetry), surface properties (AFM, FIB-SEM, goniometry, electrokinetic analysis), and crystallinity (XRD). In this work,information is summarized from the following areas: (i) Irradiation of polymers (PET) with a linearly polarized laser light (KrF), resultingin the formation of coherent ripple patterns with a lateral periodicity in the order of laser light wavelength and a structure depth of several 10 nm. (ii) Plasma ablation and liquid etching (e.g., in water, methanol) of selected polymer foils, determination of ablated and etched polymer masses, polymer wettability, surface morphology and chemical properties of plasma-modified and etched samples. A synergetic effect of thermal treatment and plasma irradiation was employed for cell adhesion and proliferation improvement in the case of biocompatible polymers (PLLA and PMP). (iii) Deposition of thin gold layers, resulting in continuous metal coverage, copying the nanostructured polymer surface, versus the formation of gold nanowires on the ridge of the laser-induced ripples. (iv) New methods for achieving achemical bond between Au nanoparticles and plasma-modified materials (polymer, glass). Au grafting increases both the biocompatibility of the substrate surface and consecutive adhesion of deposited gold. (v) The possibility of surface patterning of arbitrary polymer films was proposed and experimentally verified. The main approach of our experiments consists of dopingthin films with optical chromophores on polymers,particularly porphyrin molecules, and scanning doped materials with a focused laser beam. Doped polymer films were shown to mechanically respond on laser scanning, the response depending on light wavelength. (vi) Carbon structures were deposited by flash evaporation, sputtering and laser deposition onto substrates. Consequently, the adhesion and proliferation of cells on the substrate with a deposited carbon layer was studied by the in vitro method. (vii) Physical and chemical properties of the modified polymer surfaces mentioned above, such as polarity, wettability, electrical charge and conductivity, roughness and morphology, rigidity or elasticity, as well as the presence of various chemical functional groups that strongly influence cell adhesion and proliferation, were studied.
