Freely suspended gold nanoparticle arrays

Freely suspended gold nanoparticle arrays encapsulated into multilayered LbL nanomembranes was fabricated. The multilayered polymer matrix was composed of nine bilayers of poly(allylamine hydrochloride). Such micropatterned nanomembranes preserved outstanding micromechanical properties observed for continuous nanomembranes and possessed an anisotropic mechanical response caused by different composite moduli along and perpendicular to the nanoparticle-containing stripes. A periodic variation of Raman scattering across the micropatterned array was observed for these micropatterned nanomembranes.
