    The interaction of a newly synthesized cationic intercalator amphiphile C18AO into double-stranded DNAs at the air-water interface was investigated. Polyion complex monolayers consisting of DNAs and cationic amphiphiles were prepared. Pressure-area isotherms, fluorescence measurements, Fourier transform infrared-reflection-absorption spectroscopy and quartz crystal microbalance measurements suggest that C18AO molecules can be intercalated into base-pairs of DNAs to form densely packed two-dimensional DNA arrays at the air-water interface.
