AB  - Poly(dimethylsiloxane) (PDMS) elastomer films synthesized through a cross-linking 
      reaction between hydroxyl-terminated or vinyl-terminated PDMS have been 
      homogeneously doped with silica-coated Au nanoparticles. The nanocomposite 
      synthesis involves mixing a preformed colloid of surface-modified metal 
      nanoparticles with the elastomer film precursors. The homogeneous distribution of 
      nanoparticles is demonstrated through the presence of well defined plasmon 
      absorbance bands in the visible, which clearly show that the composites retain 
      the characteristic optical properties of single Au nanoparticles. The metal 
      particle concentration could be easily tailored either through the amount or the 
      concentration of the nanoparticle colloid added. Since the Au nanoparticles are 
      not cross-linked to the polymer and the concentration of particles is relatively 
      low, we postulate that the presence of the nanoparticles does not affect the 
      mechanical properties of the films, though this remains to be confirmed.
