  • Title: DNA-mediated site-specific deposition of gold nanoparticles on silicon wafers.
    Author: Heimann KJ, Richert C.
    Journal: Nanoscale; 2010 Dec; 2(12):2579-82. PubMed ID: 20967336.
    Abstract:
    We report a method for the site-specific deposition of gold nanoparticles, as programmed by DNA sequences immobilized on the surface of silicon oxide-coated silicon wafers. After optimization of surface chemistries, selectivities of between 8:1 and 118:1 were achieved for the DNA-based sorting of populations of gold nanoparticle of 15 nm and 60 nm diameter from a common suspension via oligonucleotide duplex formation.
