Glucose Detection of 4-Mercaptophenylboronic Acid-Immobilized Gold-Silver Core-Shell Assembled Silica Nanostructure by Surface Enhanced Raman Scattering

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...

Surface-enhanced Raman scattering behaviour of 4-mercaptophenyl boronic acid on assembled silver nanoparticles.

Molecular recognition based on specific intermolecular interactions is essential for the design of sensors with high selectivity. Herein, we report the surface-enhanced Raman scattering (SERS) behaviour of 4-mercaptophenyl boronic acid (MPBA) on self-assembled silver nanoparticles and its interaction with d-glucose. It is demonstrated that the orientation and existing form of the MPBA strongly ...

Removal of Malachite Green by Using Immobilized Glucose Oxidase Onto Silica Nanostructure-Coated Silver Metal-Foam

Enzymes Immobilization onto different types of the substrate could be helpful in various applicationsof biomedical devices and biosensors. Enzyme activity and stability could be affected by support andmethod of immobilization. In this study, the silver metal foam was successfully synthesized by thesoft-shell method and then was coated with silica. Then, glucose oxidase (GOx) immobilized on nonc...

Gold-silver bimetallic porous nanowires for surface-enhanced Raman scattering.

Highly porous bimetallic nanowires manufactured via a simple galvanic reaction have demonstrated superior activity in surface-enhanced Raman scattering, allowing ultrasensitive chemical detections on isolated porous nanowires in comparison to pristine silver nanowires.
