Controlling the Nanoscale Gaps on Silver Island Film for Efficient Surface-Enhanced Raman Spectroscopy

open access: yesNanomaterials, 2019
We control the nanoscale gaps on silver island films by different processing methods and investigate the surface-enhanced Raman scattering (SERS) efficiency on the films.

Nanoelectronic thermometers optimised for sub-10 millikelvin operation [PDF]

open access: yes, 2015
We report the cooling of electrons in nanoelectronic Coulomb blockade thermometers below 4 mK. Above 7 mK the devices are in good thermal contact with the environment, well isolated from electrical noise, and not susceptible to self-heating.

Enhancement of the Chemiluminescence Response of Enzymatic Reactions by Plasmonic Surfaces for Biosensing Applications

open access: yesNano Biomedicine and Engineering, 2015
We report the enhancement of chemiluminescence response of horseradish peroxidase (HRP) in bioassays by plasmonic surfaces, which are comprised of (i) silver island films (SIFs) and (ii) metal thin films (silver, gold, copper, and nickel, 1 nm thick ...

Spectrally selective fluorescence imaging of Chlorobaculum tepidum reaction centers conjugated to chelator-modified silver nanowires [PDF]

open access: yes, 2017
A polyhistidine tag (His-tag) present on Chlorobaculum tepidum reaction centers (RCs) was used to immobilize photosynthetic complexes on a silver nanowire (AgNW) modified with nickel-chelating nitrilo-triacetic acid (Ni-NTA).

Giant third optical harmonic generation in island silver films

open access: yesJournal of Experimental and Theoretical Physics Letters, 2004
Giant third optical harmonic (TH) generation has been experimentally observed in island silver films. The TH intensity in the island silver films studied is more than two orders of magnitude higher than the value observed for the smooth surface of a homogeneous silver film. The mechanism of enhancement of the nonlinear cubic response is associated with

Electrochemical deposition of SERS active nanostructured silver films

open access: yesInternational Journal of Electrochemical Science, 2013
An electrochemical multiple scan cyclic voltammetry (CV) method was used to prepare surface- enhanced Raman scattering (SERS) active silver island films to investigate the effect of potential scan rate and number of CV scans on the SERS performance.
