中文摘要 | single-walled carbon nanotubes (swnts) have been considered as the leading candidate for nano-device applications ranging from gene therapy and novel drug delivery to membrane separations. the miniaturization of dna-nanotube devices for biological applications requires fully understanding dna-nanotube interaction mechanism. we report here, for the first time, that dna destabilization and conformational transition induced by swnts are sequence-dependent. contrasting changes for swnts binding to poly[dgdc]:poly[dgdc] and poly[dadt]:poly[dadt] were observed. for gc homopolymer, dna melting temperature was decreased 40 degrees c by swnts but no change for at-dna. swnts can induce b-a transition for gc-dna but at-dna resisted the transition. our circular dichroism, competitive binding assay and triplex destabilization studies provide direct evidence that swnts induce dna b-a transition in solution and they bind to the dna major groove with gc preference. |
