Gold, Silver and Iron Oxide Nanoparticles: Synthesis and Bionanoconjugation Strategies Aimed at Electrochemical Applications

摘要: Nanomaterials have revolutionized the sensing and biosensing fields, with development of more sensitive selective devices for multiple applications. Gold, silver iron oxide nanoparticles played a particularly major role in this development. In review, we provide general overview synthesis characteristics gold, nanoparticles, along main strategies their surface functionalization ligands biomolecules. Finally, different architectures suitable electrochemical applications are reviewed, as well fabrication procedures. We conclude some considerations from authors’ perspective regarding promising use these materials challenges to be faced near future.
