Enhanced single molecule fluorescence and reduced observation volumes on nanoporous gold (NPG) films.

چکیده
We report single molecule fluorescence studies on nanoporous gold films. We observed dramatically enhanced intensities in individual immobilized fluorophores and reduced effective observation volumes in the nanopores. The enhanced localized plasmon field existing in the "nanovoid" regions can be visualized from the overlaid mapping image derived from surface reflectance and fluorescence emission.

A strategy for fabricating nanoporous gold films through chemical dealloying of electrochemically deposited Au-Sn alloys.
We report a novel strategy for the fabrication of nanoporous gold (NPG) films. The fabrication process involves the electrodeposition of a gold-tin alloy, followed by subsequent chemical dealloying of tin. Scanning electron microscopy (SEM) images show a bicontinuous nanoporous structure formed on the substrates after chemical dealloying. Energy dispersive x-ray (EDX) analysis indicates that th...
متن کاملA Comparative Plasmonic Study of Nanoporous and Evaporated Gold Films
Previously, we have reported that nanoporous gold (NPG) films prepared by a chemical dealloying method have distinctive plasmonic properties, i.e., they can simultaneously support localized and propagating surface plasmon resonance modes (l-SPR and p-SPR, respectively). In this study, the plasmonic properties of NPG are quantified through direct comparison with thermally evaporated gold (EG) fi...
متن کاملFabrication of 3D Nanoporous Gold with Very Low Parting Limit Derived from Au-based Metallic Glass and Enhanced Methanol Electro-oxidation Catalytic Performance
Nanoporous gold (NPG) with bi-continuous ligaments and pores structure has promising potential in functional applications, among which one prominent example is fuel cell electrocatalyst. However, current application of NPG is mostly limited to methanol electro-oxidation due to its weak catalytic performance. Here we report a simple chemical dealloying process, for generating peculiar three-dime...
متن کاملPatterned nanoporous gold as an effective SERS template.
We demonstrate large area two-dimensional arrays of patterned nanoporous gold for use as easy-to-fabricate, cost-effective, and stable surface enhanced Raman scattering (SERS) templates. Using a simple one-step direct imprinting process, subwavelength nanoporous gold (NPG) gratings are defined by densifying appropriate regions of a NPG film. Both the densified NPG and the two-dimensional gratin...
متن کاملElectrochemical tuning of the optical properties of nanoporous gold
Using optical in-situ measurements in an electrochemical environment, we study the electrochemical tuning of the transmission spectrum of films from the nanoporous gold (NPG) based optical metamaterial, including the effect of the ligament size. The long wavelength part of the transmission spectrum around 800 nm can be reversibly tuned via the applied electrode potential. The NPG behaves as dil...
