Au, Ag and Au-Ag nanoparticles: microwave-assisted synthesis in water and applications in ceramic and catalysis

Blosi M., Albonetti S., Gatti F., Dondi M., Migliori A., Ortolani L., Morandi V., Baldi G., Istec-CNR, IT

The research was focused on the synthesis of Au, Ag and Au-Ag core-shell sols, prepared by a patented microwave-assisted green synthesis. The method provides colloidal mono and bimetallic nanoparticles throughout the reduction of precursor’s salts [...]

Immobilization of Enzymes on Functionalized Magnetic Nanoparticles for Efficient Biocatalysis

Wang D.I.C., Wang W., Li Z., Wang D.I.C., Wang W., National University of Singapore, SG

In this paper, iron oxide magnetic nanoparticles were synthesized by co-precipitation method and were functionalized with aldehyde group. Spherical superparamagnetic nanoparticles with diameter of 100 nm were obtained based on the results of field emission [...]

Formation of Ni/NiO core/shell nanostructures and their attachment on carbon nanotubes

Chopra N., Claypoole L., Bachas L.G., University of Alabama, US

We report a facile wet synthesis method coupled with microwave irradiation to successfully control the morphology of Ni/NiO core/shell nanoparticles. Furthermore, we report for the first time, microwave-based synthesis of hollow NiO nanostructures from Ni [...]

Zinc Sulfide and Cadmium Sulfide based Nanocrystals and Shells

Balaguera M., Perales-Perez O., Rivera-Montalvo L., Singhal R., Tomar M.S., University of Puerto Rico, PR

The objective of the current research is to synthesize CdS, ZnS nanocrystals through a two phases-method were quantum dots moved from the aqueous phase to the organic one after proper coating of the particles by [...]

A Fluorescence Spectroscopy Study on the Encapsulation of Hydrophobic Dyes in Core-Shell Nanoparticles

Chavez J.L., Wong J.L., Duran R.S., University of Florida, US

Novel core-shell nanoparticles were prepared as encapsulating agents for fluorescent organic dyes. These particles protect the dyes from polar solvents, allowing their use in aqueous environments, such as biological systems. The nanoparticles were synthesized using [...]

A Novel Biodegradable System Based on BSA/PCL Core-shell Structured Nanofibers for Controlled Drug Delivery

Feng Y., Zhang Y.Z., Yong T., Ramakrishna S., National University of Singapore, SG

Electrospun core-shell structured nanofibers encapsulating BSA were explored as a potential drug delivery model in a biological system in present study. These nanofibers were prepared by coaxial electrospinning method with poly (caprolactone) (PCL) as the [...]
