Abstract

Recently reported patents and experimental articles on the synthesis, properties, and main applications of coreshell nanoparticles, containing iron or its oxides and gold, as well as trimetallic systems on their basis, are reviewed. These nanostructures were obtained by a series of methods, including reduction in reverse micelles, decomposition of organometallic compounds, electron-beam, laser and γ-irradiation, sonolysis and electrochemical methods. (Fe or FexOy)/Au nanoparticles are subject to be functionalized with organic moieties, may expand their main applications, which consist of catalysis, biological and biomedical uses.

Keywords: Bimetallic core-shell nanoparticles, gold/iron oxide nanoparticles, catalysis, biosensors, medical applications
