| Abstract: | In order to study the molecular recognition ability of DNA and different behavior of dyes incorporated into the base pairs,
DNA molecule was assembled layer by layer via a Zr(IV) ion. The UV absorption spectra showed the uniform layer assembly of
the DNA film. The fabricated DNA film was water-insoluble and maintained the native B-form structure. UV and CD measurements
showed that the DNA film could intercalate ethidium bromide (EtBr). |
