The need of new biocompatible materials with superior properties and flexibility in their surface termination and functionalization for medical applications is constantly increasing. Due to the combination of intrinsic properties, chemically deposited diamond thin films are proposed as one of the most promising material in this field. They are chemically/ mechanically/physically stable and their surface can be modified by a variety of chemical or plasmatic techniques. In the present work, different diamond nano-structures, i.e. nano-rods, ultra nano-cones and nano-cones, were prepared by plasma etching process by applying various masking materials (Ni, Au and diamond powder). The impact of these diamond nanostructures on the growth of human osteoblasts was investigated by fluorescence microscopy. We observed that adhesion of osteoblasts varied, depending upon the diamond nano-structure as visualized, 1 or 48 h after seeding. Many but very fine focal adhesions are formed on nano-rods; however, few but large ones are formed on ultra nano-cones and nano-cones. The cell adhesion was controlled by the nano-structuring, thereupon their usage in bio-medical applications is considered.

“…To note, the thermal treatment of the thin metal layers was also realized in microwave plasma (H2, 500 °C for 10 min, Figure 1b). This treatment resulted in the formation of nano-sized metal droplets on diamond surface [9]. In the case of thermo-catalytically driven reactions, the processing of samples with Ni droplets were performed in the same microwave plasma system using different process parameters (H2, ~1000 °C for 30 min to 2 h, Figure 1d).…”

In the present study, we introduce various technological approaches for fabrication of structured boron-doped diamond (BDD) electrodes, i.e., nanocones and nanorods which are used as working electrodes for electrochemical measurements. Structured BDD were realized either by reactive ion etching employing gold nanoclusters as the mask or by thermo-catalytically induced modification of the diamond surface. All samples were characterized in terms of surface morphology (scanning electron microscopy images), chemical composition (Raman spectroscopy) and electrochemical properties (anodic stripping voltammetry).

“…This treatment resulted in the formation of nano-sized metal droplets on diamond surface [15]. The formed metal droplets were used as the masking material during the capacitively coupled plasma reactive ion etching (CCP-RIE) in 40 % of CF 4 in O 2 for 10 min at 0.12 mbar and 100 W [27].…”

Diamond and/or carbon thin films are in the center of interest due to their variability and extraordinary combination of intrinsic properties. However, some applications require fabrication of films with tailored properties. Especially, fabrication of periodic structures is highly attractive due to their increased surface area. In this contribution we point out the key technological aspects for fabrication of micro-and nano-sized carbon-based structures. Three representative structures are presented: diamond nanorods, self-assembled templates and self-standing diamond membranes. We found that the diameter of diamond nanorods can be controlled in a broad range from 10 to 200 nm by the masking material (Au vs Ni) and its initial thickness (from few to tens of nanometers). The assembly of polystyrene microspheres in mono-or multi-layer with square or hexagonal periodicities was controlled by the spin-coating parameters. The diamond porous membrane was selectively grown on Si substrate with an interdigital or mesh like geometry. Advantages of each structure as well as the fabrication limitations are discussed more in detail and finally their representative applications are pointed out.K e y w o r d s: diamond, carbon, nanorods, microsphere lithography, selective area deposition, SEM
