Electrostatic-assembly-driven formation of micrometer-scale supramolecular sheets of (3-aminopropyl)triethoxysilane(APTES)-HAuCl4 and their subsequent transformation into stable APTES bilayer-capped gold nanoparticles through a thermal process

In this letter, we demonstrate for the first time the electrostatically driven assembly of (3-aminopropyl)triethoxysilane (APTES) and HAuCl(4) in aqueous media into novel micrometer-scale supramolecular sheets and their subsequent transformation into small, stable APTES bilayer-capped gold nanoparti...

520 |a In this letter, we demonstrate for the first time the electrostatically driven assembly of (3-aminopropyl)triethoxysilane (APTES) and HAuCl(4) in aqueous media into novel micrometer-scale supramolecular sheets and their subsequent transformation into small, stable APTES bilayer-capped gold nanoparticles through a thermal process. The nanoparticle formation mechanism is also discussed
