In the Ultrafast Laser Micro- and Nano- processing (ULMNP) laboratory, Savvas Georgiou, of IESL research is focused on the development of novel ultrafast pulsed laser processing schemes for controlled structuring at micro- and nano- scales of a variety of materials, including biopolymers. By applying ultrafast UV and IR laser pulses novel surface structures with sub-micron sized features are produced while the physical properties of semiconductor, dielectric and metallic surfaces are significantly modified. Developed methods include laser micro/nano surface structuring performed in different media, laser-induced forward transfer deposition and combination of those. Further control over the surface topology is achieved by proper functionalization of the 3D structures obtained with well-defined nanostructures. In particular, the artificial surfaces developed by processing under gaseous environments exhibit controlled dual-scale roughness, that mimics the hierarchical morphology of natural surfaces with exciting properties (i.e. the Lotus leaf), comprising micro-conical structures decorated with nanometre sized protrusions. The biomimetic morphology attained gives rise to notable multifunctional properties when combined with methods of tailoring the surface chemistry. Research shows that appropriate combination of topography and chemistry can lead to artificial surfaces that are: (a) of extremely low surface energy, thus water repellent and self-cleaned (b) smart, i.e show the ability to change their surface properties in response to different external stimuli and (c) functional in the sense that exhibit remarkable physical properties compared to the bulk. The ability to tailor the morphology and chemistry is an important advantage for the use of such structures as models to study the dependence of growth, division and differentiation of cells on the surface energy of the culture substrate and as scaffolds for tissue regeneration. At the same time, ULMNP focuses on the ultrafast laser syntheses of various types of nanomaterials including nanolayers. In particular, laser processing in liquid media results in the formation of self-organized surface nanostructures and colloids of surfactant-free nanoparticles used for photovoltaic applications. Additionally, the exploitation of ultrafast laser processing schemes for the synthesis and functionalization of graphene derivatives and other 2D materials for organic electronic applications is investigated. The ULMNP laboratory of IESL-FORTH is dedicated to the memory of Savvas Georgiou.
