New developments in nanoparticle synthesis is opening new opportunities in bottom-up assembly. Indeed, monocrystalline and functionalized nanoparticles allow fabrication of metamaterials such as plasmonics and nanogap electrodes. Among the bottom up assemb ...

Simulations and experiments of nanorods (NRs) show that co-assembly with block copolymer (BCP) melts leads to the formation of a superstructure of side-to-side NRs perpendicular to the lamellar axis. A mesoscopic model is validated against scanning electro ...

Eigenmodes are central to the study of resonant phenomena in all areas of physics. However, their use in nano-optics seems to have been hindered and delayed for various reasons. First, due to their small size, the response of nanostructures to a far-field ...

Nanofluidic systems offer a huge potential for discovery of new molecular transport and chemical phenomena that can be employed for future technologies. Herein, we report on the transport behavior of surface-reactive compounds in a nanometer-scale flow of ...

3D to 2D reorganization of silver-thiol nanostructures, triggered by solvent vapor annealing

Francesco Stellacci, Sergio Allegri

Metal-organic composites are of great interest for a wide range of applications. The control of their structure remains a challenge, one of the problems being a complex interplay of covalent and supramolecular interactions. This paper describes the self-as ...

While plasmonic antennas composed of building blocks made of the same material have been thoroughly studied, recent investigations have highlighted the unique opportunities enabled by making compositionally asymmetric plasmonic systems. So far, mainly hete ...

The resonant excitation of free electrons in metallic nanostructures enables extreme near field intensities along with a deep sub-wavelength localization of the electromagnetic energy. This has been exploited to enhance light-matter interaction down to the ...

Citrate-stabilized gold nanoparticles were found to spontaneously self-assemble into a lustrous film at a bare water–propylene carbonate interface after vigorous shaking, due to the extremely low interfacial tension. The presence of an electron donor, tetr ...

Plasmonic antennas have enabled a wealth of applications that exploit tailored near-fields and radiative properties, further endowed by the bespoke interactions of multiple resonant building blocks. Specifically, when the interparticle distances are reduce ...

In this work, we demonstrate a nanofabrication technique based on thermal scanning probe lithography (t-SPL), PDMS molding, and bottom-up capillary-assisted particle assembly (CAPA). The repeatability of the pattern transfer from the thermal sensitive poly ...
