Cerium Oxide Core-Shell Gold Nanoparticles

Product Overview

Cerium oxide core-shell gold nanoparticles are composite nanomaterials where gold nanoparticles are encapsulated or modified by cerium oxide (CeO₂). This composite material combines the surface plasmon resonance (SPR) effects of gold with the redox properties of cerium oxide, offering unique physicochemical properties with broad applications, particularly in catalysis, photothermal therapy, and biomedicine.

Key Features
