Outline of Final Research Achievements |
(1) The creation of quasicrystals by double-encoded DNA functionalized nanoparticles (DNA-NPs) on supported lipid bilayer (SLB). DNA-NPs, which were encoded by two types of DNA single-strands, were diffused, assembled and crystallized on SLB. Two-lengthscale particle formations were realized by using the double-encoded DNA-NPs. (2) Nanoparticle quasicrystal assembly mediated by designed DNA nanostructures. DNA-NPs were assembled by using DNA tetrahedral constructs. We studied optimum conditions of the lengths of DNA linkers and base sequences of recognition sites for assembling nanoparticle quasicrystals.
