Journal ArticleDOI
Optimized surface-enhanced Raman scattering on gold nanoparticle arrays
Nordin Félidj,Jean Aubard,Georges Lévi,Joachim R. Krenn,Andreas Hohenau,Gerburg Schider,Alfred Leitner,Franz R. Aussenegg +7 more
TL;DR: In this article, the maximum of the surface plasmon resonance of elongated gold nanoparticles to a wavelength, the position of which is precisely midway between the exciting laser line and the Raman line, was used to optimize the surface-enhanced Raman scattering effect.
Journal ArticleDOI
Controlling the optical response of regular arrays of gold particles for surface-enhanced Raman scattering
Nordin Félidj,J. Aubard,Giuseppe Levi,Joachim R. Krenn,Marco Salerno,Gerburg Schider,Bernhard Lamprecht,A. Leitner,Franz R. Aussenegg +8 more
TL;DR: In this article, the optical response of regular arrays of gold nanoparticles has been studied to improve the understanding of surface-enhanced Raman scattering (SERS), which can be tuned to almost any desirable wavelength by varying the particle shape, size, and spacing.
Journal ArticleDOI
Surface plasmon propagation in microscale metal stripes
Bernhard Lamprecht,Joachim R. Krenn,Gerburg Schider,Harald Ditlbacher,Marco Salerno,Nordin Félidj,A. Leitner,Franz R. Aussenegg,Jean-Claude Weeber +8 more
TL;DR: In this paper, surface plasmons are realized by a prism coupling arrangement involving an opaque aluminum screen for a distinct separation of excitation and propagation region, and the surface plasmon propagation length as a function of film widths is measured by detecting stray light due to surface plasar scattering with a conventional optical microscope.
Journal ArticleDOI
Fluorescence imaging of surface plasmon fields
Harald Ditlbacher,Joachim R. Krenn,Nordin Félidj,Bernhard Lamprecht,Gerburg Schider,Marco Salerno,Alfred Leitner,Franz R. Aussenegg +7 more
TL;DR: In this paper, surface plasmon fields can be imaged in real time by detecting the fluorescence of a molecular film close to the plasman carrying metal surface, which can be used to image the field profile of surface plasmons launched at lithographically designed nanoscopic defects.
Journal ArticleDOI
A scheme for detecting every single target molecule with surface-enhanced Raman spectroscopy.
Eric C. Le Ru,Johan Grand,Idrissa Sow,Walter R. C. Somerville,Pablo G. Etchegoin,Mona Tréguer-Delapierre,Gaëlle Charron,Nordin Félidj,Georges Lévi,Jean Aubard +9 more
TL;DR: A simple scheme, based on selective adsorption of the target analyte at the SERS hot-spots only, that allows in principle detection of every single target molecule in solution.
