Abstract
A aminosilica nanocomposite layer containing a monolayer of gold nanoparticles (d = 18–22 nm) with a well-defined spacing was spontaneously deposited on an unmodifiedpolystyrene surface via a sol–gel reaction when the reduction reaction was carried outunder 1:8 molar ratio (gold(III):aminosilane). The amount of aminosilica and spacingbetween gold nanoparticles were found to be a function of the aminosilane:water molarratio, which contributes to the plasmonic property of the films with its absorptionwavelength ranging between 701 and 548 nm. Furthermore, the nanocomposite film thatconsists of a monolayer of nanoparticles in aminosilica has also been deposited on thesurface of polystyrene beads. This core–shell structure was found capable of storingelectrostatic charges and forming a well-separated 2D array.
