Gold nanoparticles obtained by pulsed laser ablation in liquids: formation of monolayers on chemically functionalized patterns/substrates

摘要

The advantages of nanoparticles (NPs) synthesized by pulsed laser ablation in liquids (PLAL) include chemical purity, high colloidal stability without capping agent due to a charged surface,a possibility of efficient in situ (bio)conjugation, and others. In the present work we show that not only colloidal solutions, but also layers formed by Au NPs synthesized by PLAL method demonstrate advantages as compared to those formed by chemically synthesized Au NPs bearing charged ligands. It is worth noting that high-quality immobilization of NPs on solid substrates is crucially important for development of solid-state nanotechnology.
