Gold functionalization thiol bonds
WebThe functionalization of spherical gold nanoparticles (AuNPs) in solution with thiol molecules is essential for further developing their applications. AuNPs exhibit a clear localized surface plasmon resonance (LSPR) at 520 nm in water for 20 nm size nanoparticles, which is extremely sensitive to the local surface chemistry. In this study, … WebThe formation of a gold–sulfur bond is the driving force for the anchoring of thiol ligands on either gold surfaces, nanoparticles or clusters, 71 leading to the formation of self-assembled monolayers (SAM). 72 From the available structural investigations it emerges that the staple-type binding motif is the preferred structure element of the ...
