Co Au Pd Pt Cu Core Shell Nanoparticles (Cobalt/Gold, Palladium, Platinum, Copper, 99.99%, APS: 80-100nm)

Co Au Pd Pt Cu Core-Shell Nanoparticles

Introduction:

Co Au Pd Pt Cu Core-shell nanoparticles is a noble metal with high electrical conductivity and biocompatibility. When combined in a core-shell structure, Co/Au core-shell nanoparticles can exhibit a unique set of properties derived from the combination of the magnetic core and the gold shell.

Co/Au core-shell nanoparticles are typically prepared by electrochemical deposition, chemical vapor deposition, or solution-phase methods, where Cobalt (Co) serves as the core and Gold (Au) is deposited as a shell around it.

Properties

Magnetic Properties: The Cobalt core imparts ferromagnetic behavior to the nanoparticles. The magnetic properties of Co nanoparticles are useful for applications in magnetic resonance imaging (MRI), data storage, and magnetic separation.

Surface Plasmon Resonance (SPR): The gold shell can support surface plasmon resonance (SPR), which can be used to enhance optical properties such as light scattering and absorption, particularly in biosensing and imaging applications.

Applications

Biomedical Imaging: The magnetic properties of Co can be utilized for MRI, while the gold shell enhances the ability of these nanoparticles to scatter light, making them useful in optical imaging.

Drug Delivery: The gold shell can be functionalized with biological ligands, and the magnetic properties of the Co core can be employed for targeted drug delivery or magnetic-controlled release.

Au/Pd Core-Shell Nanoparticles (Gold/Platinum)

Introduction

Gold (Au) is a highly conductive, stable, and biocompatible metal, while Platinum (Pd) is a well-known catalyst with excellent catalytic properties, especially in hydrogenation and dehydrogenation reactions. When gold (Au) is used as the core and platinum (Pd) is deposited as the shell, the resulting core-shell nanoparticles combine the electronic properties of gold with the catalytic efficiency of platinum.

Properties

Catalytic Properties: The platinum shell contributes to high catalytic activity, especially for reactions such as hydrogenation, oxidation, and fuel cell reactions. The platinum layer is often responsible for providing the active sites necessary for efficient catalysis.

Stability and Conductivity: The gold core enhances the electrical conductivity of the nanoparticles, which makes them suitable for electrochemical and electrocatalytic applications.
