Surface Enhanced Raman Scattering of Crystal Violet with Low Concentrations Using Self-Assembled Silver and Gold-Silver Core-Shell Nanoparticles

The active substrates in surface enhanced Raman scattering (SERS) spectroscopy were prepared through self-assembly of nanoparticles on functionalized glasses. Colloidal silver nanoparticles (Ag NPs) were prepared chemically in two different sizes by reduction of AgNO3 using trisodium citrate and sodium borohydride. Gold–silver core–shell nanoparticles were also prepared to compare between the o...

Self - Assembled Monolayers of Ferrocenylazobenzenes on Au ( 11 1 ) lRlica Films : Surface - Enhanced Raman Scattering Response vs Surface Morphology

Surface-enhanced Raman scattering (SERS) and surface-enhanced resonance Raman scattering (SERRS) results are reported for self-assembled monolayers (SAMs) of 4-(4-mercaptobutyl)-4‘-ferrocenylazobenzene, compound 1, on Admica and Wmica thin films. Two different Admica surfaces, designated Au(rough)/ mica and Au(lll)/mica, have been characterized by atomic force microscopy (AFM) to define their r...

Raman-encoded microbeads for spectral multiplexing with SERS detection

Simultaneous detection of multiple molecular targets can greatly facilitate early diagnosis and drug discovery. Encoding micron-sized beads with optically active tags is one of the most popular methods to achieve multiplexing. Noble metal nanoparticle labels for optical detection by surface-enhanced Raman spectroscopy (SERS) exhibit narrow bandwidths, high photostability and intense Raman signa...

Improvement of Desulfurization Performance of Rhodococcus erythropolis IGTS8 by Assembling Spherical Mesoporous Silica Nanosorbents on the Surface of the Bacterial Cells

MCM-41 mesoporous silica is synthesized based on a self assembly method, using a quaternary ammonium template, CTAB for the adsorption of sulfur compounds from model oil (1.0 mmol/l DBT in dodecane solution). Then the adsorption capability of MCM-41 assembled on the surface of bacterium Rhodococcus erythropolis IGTS8 is examined regarding the improvement of the biodesulfurization process of...

Self-assembly of subwavelength nanostructures with symmetry breaking in solution.

Nanostructures with symmetry breaking can allow the coupling between dark and bright plasmon modes to induce strong Fano resonance. However, it is still a daunting challenge to prepare bottom-up self-assembled subwavelength asymmetric nanostructures with appropriate gaps between the nanostructures especially below 5 nm in solution. Here we present a viable self-assembly method to prepare symmet...
