A Computational Study to Understand the Surface Reactivity of Gold Nanoparticles with Amines and DNA
We conducted a computational adsorption study of methylamine on various surface-models of gold nanoparticle which is facetted by multiple {111} and {100} planes. In addition to these flat surfaces, our models include the stepped surfaces (ridges) for

We have discovered that the current protocols to assemble Au nanoparticles based on DNA hybridization do not work well with the small metal nanoparticles (e.g. 5 nm Au, 3.6 nm Pt and 3.2 nm Ru particles). Further investigations revealed the presence
