Abstract

Interfacial properties and organization process of DNA/octadecylamine (ODA) mixed Langmuir monolayers at die air/water interface were investigated. The morphology and structure of transferred DNA/ODA mixed LB film were observed using AFM. It was found that fractal domains appeared in the mixed films at low surface pressure. At higher pressure, the domain changed from network structure to aggregated clusters. Several kinds of DNA LB films with patterned surfaces and specific structures were prepared. It provides a good template for the fabrication of complex nanoscale devices.

Key words: octadecylamine, DNA, PHASE TRANSFORMATION, AFM, Langmuir-Blodgett FILMS
