Combinatorial templates generated by dip-pen nanolithography for the formation of two-dimensional particle arrays.
Lattices of single polystyrene particles were constructed by using a combinatorial approach to analyze particle pattern recognition properties. Dip-pen nanolithography was used to generate chemical templates of 16-thiohexadecanoic acid on a gold surface to study the two-dimensional assembly of amine- and amidine-modified particles.
