Latex nanoparticles (100 nm and 200 nm diameter) were precisely located onto the gold regions of micro and nanopatterned gold/silica substrates through surface chemical functionalizations. The gold patterns were selectively functionalized with alkylthiols bearing biotin or amine headgroups. This selective functionalization allowed the trapping of streptavidin- or carboxy-functionalized latex nanoparticles onto the gold structures with very little non-specific adsorption onto the surrounding silica. Quantitative data of nanoparticle capture on gold and silica, obtained through SEM image analysis, showed a one to two order of magnitude increase on gold with a similar low coverage on silica (non-specific adsorption) thanks to chemical functionalizations. Single nanoparticles were captured at the gap of dimer gold nanostructures. (C) 2014 Elsevier Inc. All rights reserved.
