title: Characterization of COOH-Molecules Self-Asembled on Gold Nanoparticles
creator: Nguyen, Kien Cuong
subject: Engineering Physics
description: 11-MUAsolution of the concentration of 10mM was deposited on a gold sutface through the self-assembled molecules. The gold surface was characterized by AFM-topography and XRD-spectrum. Both results show that the gold surface was composed of gold nanoparticles (AuNPs) piling up on each other and the most significant peak, centered at 2θ = 38.2°, is originated from the face centered cubic gold, respectively. COOH-functional molecules were self-assembled onto AuNPs surface through the reaction between thiol molucules and AuNPs to from the AuS binding. The IR spectrum of a COOH-terminated AuNP sample show the existence of  carbonyl (C=O) and hydroxyl (OH) molecules on AuNP surface. Furthermore, COHNFITC@SiO2 bonding to AuNPs, observed on a confocal microscope, also revealed the COOH-molecules selft-assembled to AuNP-sample.
