摘要：
A method of preparing large area patterned 2D arrays of uncapped gold (An) nanoparticles has been developed. The pattern has been formed. using self-assembly of uncapped An nanoparticles. The An nanoparticles were synthesized via toluene/water two phase systems using a reducing agent and colloidal solution of An nanoparticles was produced. These nanoparticles have been prepared without using any kind of capping agent. Analysis by TEM showed discrete An nanoparticles of 4 nm average diameter. AFM analysis also showed similar result. The TEM studies showed that these nanoparticles formed self-assembled coherent patterns with dimensions exceeding 500 nm. Spin coating on silicon substrate by suitably adjusting the speed can self-assemble these nanoparticles to lengths exceeding 1 mu m.
