摘要：

A DNA-lipid cast film was prepared, in which counter cations of DNA phosphates were replaced by cationic amphiphiles. The film is transparent, physically strong, and water-insoluble. DNA strands could be aligned in one direction by stretching the film. The aligned-DNA film showed a large anisotropic and ohmic electric current (10(-5) S cm(-1), A(perpendicular to)/A(parallel to) = 10(4)) along DNA strands in the film.
