A phenomenon was observed in our laboratory as we studied the effect of chain length of fatty amine capped on the nanogold upon their 2D arrangement. The nanogolds modified with C12NH2, C16NH2, C18NH2 have been used in this investigation and were arranged by the method of LB technique. Electronmicrograms showed that the length of aggregates is proportional to the chain length of the capped amine CnNH2. The longer the chain length is, the straighter the aggregates will be and the more compact 2D arrangement could be formed. Linear aggregates has been found in the 2D pattern formation of nanoparticles without template, and these kinds of aggregates might be of great importance in the formation of 2D arrangement of nanoparticles.
