AbstractAn optimized reverse micelles sol-gel composition was deposited by inkjet direct patterning onto glass supports. Experimental “material printer” Fujifilm Dimatix 2831 was used for sol patterning. Printing was repeated up to 4 times in wet-to-dry manner and photocatalytic coatings of various thickness were obtained after final thermal calcination. Basic material properties of prepared coating were studied by optical microscopy, electron and atomic force imaging, Raman, XRD and UV-VIS spectrometry. Photocatalytic activity was evaluated by dye and fatty acid degradation rate as well as photoinduced hydrophilic conversion rate. Reverse micelles proved to be viable synthetic route for the preparation of titania coatings with even structure and their compatibility with inkjet direct patterning deposition was demonstrated.

We have demonstrated direct patterning of surface initiator layer (SIL) for Atom Transfer Radical Polymerization (ATRP) using a sol–gel based “ink” containing (p-chloromethyl)phenyltrimethoxysilane and tetraethoxysilane for an inkjet printer. Mechanically/chemically robust and smooth micropatterns of SIL several tens of micrometer in width and 15 nm thickness were directly printed on silicon substrates under mild conditions (open to the atmosphere, at ~28 °C under >60% relative humidity). Subsequent surface-initiated ATRP of glycidyl methacrylate (GMA) under the air atmosphere gave area-selective/stepwise growth of homogeneous polyGMA brushes (pGMA) from the micropatterns of SIL. This area-selective growth of pGMA was also confirmed by a fluorescence microscopy. Because of chemical reactivity of epoxy groups on the grafted pGMA surfaces toward amino-functionalized nanomaterials, CdS/ZnS-alloyed quantum dots were spatially deposited only on the pGMA-covered regions with a complete area-selectivity.

AbstractIn this article we will show three recent examples of combined strategies aiming at merging top-down and bottom-up approach for nanofabrication at nanoscale level. The first example shows the fabrication of nanogaps performed by Focus Ion Beam technique that have been used to measure the conductivity of few gold nanoparticles aggregates deposited by Dip Pen lithography. The second example deals with the parallel replica of high resolution master generated by Electron Beam lithography by means of an innovative lithographic process based on DNA supramolecular nano-stamping. The latter example proposes the possibility to generate, through radiation exposure, direct patterning of hybrid sol gel material doped with fluorescent molecules. The outline of the fabrication approaches and their scientific and technical perspective are discussed.
