Wavelength-scanned surface-enhanced Raman excitation spectroscopy.
A detailed wavelength-scanned surface-enhanced Raman excitation spectroscopy (WS SERES) study of benzenethiol adsorbed on Ag nanoparticle arrays, fabricated by nanosphere lithography (NSL), is presented. These NSL-derived Ag nanoparticle array surfaces are both structurally well-characterized and extremely uniform in size. The WS SERES spectra are correlated, both spatially and spectrally, with...
متن کاملGlucose Sensing with Surface-Enhanced Raman Spectroscopy
Diabetes mellitus is a chronic disorder that requires careful regulation of blood-glucose levels in order to maintain the health of diabetic patients. Failure to regulate these levels within tight limits leads to severe secondary health complications to the diabetics’ retina, kidneys, nerves, and circulatory system [1]. Most commonly, diabetics measure blood-glucose levels four to six times per...
متن کاملPlasmon Scanned Surface-Enhanced Raman Scattering Excitation Profiles
Since the discovery of surface-enhanced Raman spectroscopy (SERS) in 1977, scientists have come to understand the enhancement mechanism, but have been unable to consistently optimize the weak signals inherent in Raman experiments. Surface-enhanced Raman signals originate from excitation of the localized surface plasmon resonance (LSPR) of a nanostructured metal surface, thus producing concentra...
متن کاملLocalized and propagating surface plasmon co-enhanced Raman spectroscopy based on evanescent field excitation.
The localized and propagating surface plasmon co-enhanced Raman scattering of 4-mercaptopyridine was observed based on evanescent field excitation. The most effective coupling of the localized and propagating surface plasmons resulted in a >50 times enhanced signal relative to signals obtained on vacuum-deposited silver film.
متن کاملPlasmon-Enhanced Surface Photovoltage of ZnO/Ag Nanogratings
We investigated the surface photovoltage (SPV) behaviors of ZnO/Ag one-dimensional (1D) nanogratings using Kelvin probe force microscopy (KPFM). The grating structure could couple surface plasmon polaritons (SPPs) with photons, giving rise to strong light confinement at the ZnO/Ag interface. The larger field produced more photo-excited carriers and increased the SPV. SPP excitation influenced t...
