This paper outlines a simple step-wise method for
making micro-patterned dual nanoparticle thin films. Silver
nanoparticles that are coated with polystyrene are mixed with a di-block
copolymers that are then annealed to yield microarrays (lamellae in the
case of symmetric and cylindrical in the case of asymmetric BCPs) where
the silver NPs were localized to only the PS domains. In a second step,
a variety of secondary nanoparticles can be added on the surface where
they preferentially interact with the vinylpyridine domains.
