Plasmonic properties of film over nanowell surfaces fabricated by nanosphere lithography
Article Abstract:
An elaborated and orderly study of the plasmonic properties of a film over nanowell surface using lithography and reactive ion etching and structurally characterized by AFM and SEM is investigated. The results show that if the nanowell is deep enough compared to the metal film thickness the disk can couple through air and the two-dimensional array is specifically fabricated to take advantage of diffractive coupled plasmon resonance.

Electrostatically-directed self-assembly of cylindrical peptide amphiphile nanostructures
Article Abstract:
Theoretical studies of peptide amphiphile nanostructures created by stupp and co-workers is presented ad shown that these amphiphiles exhibit attractive electrostatic interactions between their hydrophilic headgroups. The interactions prevail in their competition with the hydrophobic attraction between the amphiphile tails for the shape of the self-assembly leading to cylindrical micelles of nanoscale dimension.

Nanoscale optical biosensor: short range distance dependence of the localized surface plasmon resonance of noble metal nanoparticles
Article Abstract:
The short range distance dependence of the plasmon resonance wavelength with nanoparticle composition, shape and size are examined using five distinct measurements. The results indicate that the localized surface plasmon resonance (LSPR) nanoparticle-based optical sensor can be optimized to produce varying responses to adsorbate molecules directly on their surfaces.
