| Research Abstract |
We report a simple, convenient, and inexpensive self-assembly method for nanopatterning gold nanoparticles(AuNPs) on substrates using block copolymer nanotemplates. Well-ordered monolayer films of block copolymer micelles(BCMs) were prepared by self-assembly of polystyrene-block-poly(4-vinylpyridine)(PS-b-P4VP). The films were immersed in a solution of citrate stabilized AuNPs. After immersion, the AuNPs showed hexagonal ordering on individual BCMs. In order to evaluate the possible application of these AuNP arrays in local surface plasmon resonance(LSPR) sensors, we investigated their optical response to molecular recognition phenomena at the surface of the AuNPs.
