Biosensing Based on Surface-Enhanced Raman Spectroscopy by Using Metal Nanoparticles
Surface-enhanced Raman spectroscopy (SERS) is a promising tool in the analytical science because it provides good selectivity and sensitivity without the labeling process required by fluorescence detection. This technique consists of locating the target analyte on nanometer range of roughed Au-nanoparticles. The presence of the metal nanoparticles provides a tremendous enhancement to the result...
متن کاملGold nanoparticles combined with surface-enhanced Raman spectroscopy
Raman spectroscopy using surfaceenhanced Raman scattering (SERS) nanoparticles is an exciting new molecular imaging modality that has emerged over the past decade [1,2]. The approach is based on the inelastic scatter of photons by molecular bonds. Small-molecule dyes adsorbed on a rough metal (usually gold) surface experience a dramatic increase in their Raman scatter intensity due to surface p...
متن کاملUnification of Surface Enhanced Raman Spectroscopy of Dyes Using One Pot Synthesized Stabilized Ag Nanoparticles
stabilized Ag Nanoparticles (NPs) were synthesized using Lee-Meisel method under three different conditions in an oil bath. UV-Vis spectroscopy of the Ag NPs showed a Localized Surface Plasmon (LSP) band around 430 nm, indicating Ag NPs had a size range around 40 nm. To fabricate a surface Enhanced Raman Spectroscopy (SERS) substrate, LSP properties of Ag NPs was employed with the goal of detec...
متن کاملFabrication of lipophilic gold nanoparticles for studying lipids by surface enhanced Raman spectroscopy (SERS).
A simple fabrication method for preparing lipophilic gold nanoparticles (AuNPs) suitable for use as substrates in surface-enhanced Raman scattering (SERS) applications of lipids was developed. The AuNPs were shown to be dispersible within lipid phases, where they greatly increased the SERS signals of lipids.
