Title: Binary nanoparticle assemblies for generating chemical patterns
Author(s): Singh, G.; Pillai, S.; Besenbacher, F.; Kingshott, P.
Abstract: Many approaches have focused on preventing protein adsorption aimed at making better medical implants and more sensitive biosensors. These include; grafted polymer layers, plasma polymerisation and oligoethyleneoxide SAMs on gold. However, the long term effectiveness of these approaches remain uncertain, therefore alternative methods are of great interest particularly those that can provide a better understanding of protein-surface interactions. Chemical patterning on the nanoscale is one way of generating surface regions with low concentrations of molecules and potentially provides a platform for probing functionality down to the single molecule level. One of the promising ways of generating nanopatterns is by decoration of surfaces with nanoparticles of different size and chemical functionality. Several methods have been developed to grow binary nanoparticle assemblies such as layer-by-layer (LBL) approaches and onestep assembly. Here, we demonstrate a simple onestep process that generates ordered binary colloidal particles of different surface chemistry assembled on hydrophobic surfaces.
