Optical aggregation of gold nanoparticles for SERS
Optical forces are used to aggregate plasmonic nanoparticles and create SERS-active hot 17 spots in liquid. When biomolecules are added to the nanoparticles, high sensitivity SERS detection 18 is accomplished. Here we tailor this methodology to detect catalase and hemoglobin, two Raman 19 resonant biomolecules, at concentrations down to 10 nM and 1 pM. Subsequently, we study the 20 SERS signal ...
متن کاملGold Nanoparticles for SERS in Fingermark Identification
This note demonstrates the power of the PerkinElmer RamanStation 400 in combination with a SERS methodology to detect fingermarks on a number of substrates.
متن کاملTunable SERS using gold nanoaggregates on an elastomeric substrate.
We report on the self-assembly of colloidal gold nanoparticles on a stretchable, elastomeric membrane, and the use of this membrane as a base substrate for far-field confocal Raman measurements. Surface-enhanced Raman scattering (SERS) enhancement for such a substrate was estimated as 10(6) to 10(7). Atomic force microscopy has been used to study the changes in nanoparticle topography when the ...
متن کاملChemiresistive/SERS dual sensor based on densely packed gold nanoparticles
Chemiresistors are a class of sensitive electrical devices capable of detecting (bio)chemicals by simply monitoring electrical resistance. Sensing based on surface enhanced Raman scattering (SERS) represents a radically different approach, in which molecules are optically detected according to their vibrational spectroscopic fingerprint. Despite different concepts are involved, one can find in ...
متن کاملGold@silver bimetal nanoparticles/pyramidal silicon 3D substrate with high reproducibility for high-performance SERS.
A novel and efficient surface enhanced Raman scattering (SERS) substrate has been presented based on Gold@silver/pyramidal silicon 3D substrate (Au@Ag/3D-Si). By combining the SERS activity of Ag, the chemical stability of Au and the large field enhancement of 3D-Si, the Au@Ag/3D-Si substrate possesses perfect sensitivity, homogeneity, reproducibility and chemical stability. Using R6G as probe ...
