Gold Nanoparticle based colorimetric biosensing of various DNA types and ligands

Abstract

The purpose of this study was to test the hypothesis that an array of unmodified gold nanoparticles and various DNA types and conformations could provide qualitative and quantitative information about DNA and DNA binding ligands. The array system was designed and optimized with DNA and a range of unmodified gold nanoparticle sizes (8, 10, 13, 20nm… (More)
