This work describes the fabrication of spaced plasmonic particle arrays for systematic dark field investigation. The major advantage of those substrates is the possibility of "high" throughput single particle spectroscopy in combination with the accessibility towards post-modifications. The concept is based on directed assembly of Poly(N-isopropylacrylamide) coated plasmonic colloids on micro contact printed polyelectrolyte multilayer films. Arrays of gold core particles were overgrown with gold and studied via dark field microscopy and spectroscopy. The presented method is highly suited for efficient screening of optical properties and catalytic reactions on the single particle level (M.B. Müller, ACS Nano, 2014, 8, 9410).
