Recent simulations predict that aggregating nanospheres functionalized with polymer "tethers" can self-assemble to form a cylinder, perforated lamellae, lamellae, and even the double gyroid phase, which are phases also seen in block copolymer and surfactant systems. Nanoparticle size polydispersity is likely to be a characteristic of these systems. If too high, polydispersity may destabilize a ...

In this paper we report on the engineering of repeatable surface enhanced Raman scattering (SERS) optical fiber sensor devices (optrodes), as realized through nanosphere lithography. The Lab-on-Fiber SERS optrode consists of polystyrene nanospheres in a close-packed arrays configuration covered by a thin film of gold on the optical fiber tip. The SERS surfaces were fabricated by using a nanosph...

Abstract Synthetic antiferromagnetic (SAF) particles with perpendicular anisotropy display a number of desirable characteristics for applications in biological and other fluid environments. We present an efficient effective method the patterning ultrathin Ruderman-Kittel-Kasuya-Yoshida coupled, perpendicularly magnetised SAFs using combination nanosphere lithography ion milling. A Ge sacrificia...

We investigate the system constituted by a polarizable atom near nanosphere under influence of an external electrostatic field, showing that attractive dispersive force between them can be overcome interaction. Therefore, in addition to advantageous possibility actively tuning resultant with agent without requirement physical contact, this may also become repulsive. analyze situation different ...

The strong coupling between photons and bosonic excitations in matter produces hybrid quasiparticle states known as polaritons1–3. Their signature is the avoided crossing eigenfrequencies of coupled system illustrated by Jaynes–Cummings Hamiltonian4. It has been observed quantum electrodynamics experiments based on atoms5,6, ions7, excitons8–10, spin ensembles11,12 superconducting qubits13. In ...
