| 中文摘要 | single-walled carbon nanotubes (swnts) can selectively induce human telomeric i-motif dna formation at ph 7.0. based on this property, we design a dna nanomachine induced by swnts on gold surface. the motor dna is human telomeric g-quadruplex dna. the reversible hybridization between the motor dna and its complementary human telomeric i-motif dna can be modulated by swnts without changing solution ph. up to now, to our knowledge, there is no report to show that a dna nanomachine is induced by swnts or a dna nanomachine can detect i-motif formation at ph 7.0. our work may provide a new concept for designing an swnt-induced dna nanomachine and for the detection of i-motif dna structure at ph 7.0. dna hybridization, conformational transition and i-motif formation have been characterized on surface or in solution by fluorescence confocal microscopy, circular dichroism, dna melting and gel electrophoresis. the folding and unfolding kinetics of the dna nanomachine on gold surface were studied by fourier transform-surface plasmon resonance (ft-spr). all these results indicate that swnts can induce the dna nanomachine to work efficiently and reversibly. |
