Creating Micrometer-scale Branch-like Patterns through Nanopillar-guided Crystallization
نویسندگان
چکیده
We demonstrated an approach to generate microscale branch-like salt crystallization patterns induced by a regular nanopillar array fabricated by using the laser interference lithography system. Branches of the inorganic salt crystals had similar shapes repeating at different sizes, ranging from ~ 1 m to 20 m in width, covering the 2×2 cm 2 area patterned with nanopillars. The angles between the branches could be modulated by coating nanopillars with 20mer poly-dT nucleotides of different concentrations. This nanopillar-guided crystallization approach, we believe, provides great potential to create biomimic systems for the study of ordered structure formation between organic and inorganic interfaces.

متن کاملControl of the two-dimensional crystallization of DNA origami with various loop arrangements.
We have developed a new strategy to control the two-dimensional (2D) crystallization of DNA origami by introducing loops on the surface and aligning them in various orientations. Among the orientations tested, vertically connected loops successfully produced the 2D crystal lattice on a micrometer scale, while all other orientations failed.
متن کاملCoupled nanopillar waveguides: optical properties and applications
In this paper we review basic properties of coupled periodic and aperiodic nanopillar waveguides. A coupled nanopillar waveguide consists of several rows of periodically or aperiodically placed dielectric rods (pillars). In such a waveguide, light confinement is due to the total internal reflection, while guided modes dispersion is strongly affected by the waveguide structure. We present a syst...
