摘要：

The adsorption of DNA by the 3-,-[N-(N',N'-dimethyl amino ethane) carbamoyl] cholesterol (DC-Chol) monolayer at the air-liquid interface was studied by using the Langmuir-Blodgett film balance. With the presence of 1 g M DNA in the subphase, the surface pressure increases right at the beginning of the compression. The liquid expanded phase of the DC-Chol disappears due to the adsorption of DNA. The AFM image of the prepared DC-Chol/DNA film has tree-branch-like fractal structure with a height of 2 nm that correspond to the diameter of DNA.
