A parallel nanolithographic patterning method is presented that can be used to obtain arrays of multifunctional nanoparticles. These patterns can simply be converted into a variety of secondary nanopatterns that are useful for nanolithographic imprint, plasmonic, and etch-mask applications.

Fe-based metallic glasses (MGs) have attracted much attention because of their cheap raw materials, outstanding soft magnetic properties and superior catalytic activity. Meanwhile, the fabrication micro/nano-structures on its surface could further improve functional properties. In this study, it was attempted to fabricate a MG (Fe52Cr13Mo12C15B6Er2, in at. %) by nanosecond pulsed laser irradiat...

Using an atomic force microscope to nanopattern a substrate for liquid crystal alignment, a bend distortion is imposed on a liquid crystal. In regions of large bend the smectic-A phase melts into the nematic phase, and the width of the melted region is measured as a function of temperature. The results are consistent with type-I superconducting (nematic — smectic-A) behavior, wherein a large ma...

Nanostructured ultrathin films of pendant carbazole-modified polyelectrolytes were fabricated using the layer-by-layer deposition technique in order to correlate the importance of highly ordered structures and well-defined layer composition in electrochemical cross-linking and nanopatterning. Both UV-vis and surface plasmon resonance (SPR) spectroscopy studies indicated differences in the film ...

By merging bottom-up and top-down strategies we tailor graphene's electronic properties within nanometer accuracy, which opens up the possibility to design optical and plasmonic circuitries at will. In a first step, graphene electronic properties are macroscopically modified exploiting the periodic potential generated by the self assembly of metal cluster superlattices on a graphene/Ir(111) sur...

Characterization of cancer cells is important in case of personalized cancer therapy. Cells can be characterized based on their surface marker expression level using fluorescence or surface-enhanced Raman spectroscopy (SERS) method, but in both cases its needed additional labeling with fluorescent or Raman dyes, those may cause cellular cytotoxicity. In this study, we report silver (Ag) nanosta...
