Gold Coated Magnetic Nanoparticles for Specific Separation and Detection of Oligonucleotide Sequences and Proteins

Abstract
Monodisperse magnetic nanoparticles were produced and subsequently coated with a gold layer by the reduction at surface of a gold precursor in order to develop an integrated detection and “gene fishing” system. Functionalization of the nanoparticles could allow the application of this system to a variety of biomolecules.
