Plasmonic Sensing Using Nanodome Arrays Fabricated by Soft Nanoimprint Lithography

Autor: Gregory A. Wurtz, Christina McClatchey, Magnus P. Jonsson, Antony Murphy, John McPhillips, Richard J. Winfield, Robert Pollard, Tony Kelly

Publikováno v: The Journal of Physical Chemistry C. 115:15234-15239

Arrays of gold-coated nanodomes were fabricated on glass substrates using a soft nanoimprint lithography technique. Optical transmission measurements revealed complex plasmonic resonances that proved highly sensitive to the array dimensions, the thic

Wavelength Dependence of Raman Enhancement from Gold Nanorod Arrays: Quantitative Experiment and Modeling of a Hot Spot Dominated System

Autor: Antony Murphy, John McPhillips, Matthew Doherty, Robert Pollard, Paul Dawson

Publikováno v: The Journal of Physical Chemistry C. 114:19913-19919

Surface-enhanced Raman scattering (SERS) spectra from molecules adsorbed on the surface of vertically aligned gold nanorod arrays exhibit a variation in enhancement factor (EF) as a function of excitation wavelength that displays little correlation w

High-Performance Biosensing Using Arrays of Plasmonic Nanotubes

Autor: Antony Murphy, William Hendren, Robert Pollard, John McPhillips, Fredrik Höök, R. Atkinson, Magnus P. Jonsson, Anatoly V. Zayats

Publikováno v: ACS Nano. 4:2210-2216

We show that aligned gold nanotube arrays capable of supporting plasmonic resonances can be used as high performance refractive index sensors in biomolecular binding reactions. A methodology to examine the sensing ability of the inside and outside wa

Directed self-assembly of nanorod networks: bringing the top down to the bottom up

Autor: Antony Murphy, Joshua F. Einsle, G. Scheunert, John McPhillips, Robert M. Bowman, Robert Pollard, Anatoly V. Zayats

Publikováno v: Einsle, J, Scheunert, G, Murphy, A, McPhillips, J, Zayats, A, Pollard, R & Bowman, R 2012, ' Directed self-assembly of nanorod networks: bringing the top down to the bottom up ', Nanotechnology, vol. 23, no. 50, 505302 . https://doi.org/10.1088/0957-4484/23/50/505302

Self-assembled electrodeposited nanorod materials have been shown to offer an exciting landscape for a wide array of research ranging from nanophotonics through to biosensing and magnetics. However, until now, the scope for site-specific preparation

The controlled fabrication and geometry tunable optics of gold nanotube arrays

Autor: Antony Murphy, Gregory A. Wurtz, Christina McClatchey, William Hendren, Anatoly V. Zayats, Robert Pollard, John McPhillips, Ron Atkinson

Publikováno v: Nanotechnology. 22(4)

Arrays of vertically aligned gold nanotubes are fabricated over several square centimetres which display a geometry tunable plasmonic extinction peak at visible wavelengths and at normal incidence. The fabrication method gives control over nanotube d

Toward self-assembled ferroelectric random access memories: hard-wired switching capacitor arrays with almost Tb/in.(2) densities

Autor: P. Baxter, Finlay D. Morrison, Robert M. Bowman, Paul R. Evans, J. Marty Gregg, John McPhillips, Robert Pollard, Mark McMillen, Xinhau Zhu, James F. Scott

Publikováno v: Nano letters. 7(5)

We report on the successful fabrication of arrays of switchable nanocapacitors made by harnessing the self-assembly of materials. The structures are composed of arrays of 20-40 nm diameter Pt nanowires, spaced 50-100 nm apart, electrodeposited throug
