I wanted to know how influence the crossover is to the stability of dna structure. However I couldn't find out the way that change only the number of crossover or only the arrangement of crossover. I mean, in the fixed shape of DNA structure, the number of crossover, the crossover arrangement, the length of staple, etc the varialbes of stability are not independent. So I just created sort of pattern, and applied it to the pixed shape DNA structure. | I wanted to know how influence the crossover is to the stability of dna structure.

The cadnano structure - 2
I wanted to know how influence the crossover is to the stability of dna structure. However I couldn't find out the way that change only the number of crossover or only the arrangement of crossover. I mean, in the fixed shape of DNA structure, the number of crossover, the crossover arrangement, the length of staple, etc the varialbes of stability are not independent. So I just created sort of pattern, and applied it to the pixed shape DNA structure.

Direct observation of stepwise movement of a synthetic molecular transporter
source : http://www.nature.com/nnano/journal/v6/n3/full/nnano.2010.284.html
- By DNA system, we can make a controlled motion in nanoscale.
- In the system, DNA motor move on the DNA track
- The track consists of dna stators, and then dna motor move from one stator to the neighboring stator by a reaction.
- The reaction make dna motor move uni-directionally and the motion velocity alomost constant.(refer the thesis for the reaction details)

Relationship of metal particle and origic organic dyes in nanoscale
- In nanoscale, the distance between metal particle and organic dyes is important facter to photophysical property of the dyes.
- The closer the physical distance between metal and dye is, the weaker fluorescence intensity is and the shorter Fluorescence lifetime is.
- Each organic dye has a particular property of this phenomenon, so the fluorescence data can be used to define a matter.

Self-Assembly of Symmetric Finite-Size DNA Nanoarrays - Yan Liu, Yonggang Ke, and Hao Yan
http://pubs.acs.org/doi/pdf/10.1021/ja055614o
- The one task that Structural DNA nanotechnology has is to control the size of DNA self-assembly
- To produce effectively fixed-size DNA arrays, we need to use the geometric symmetry of DNA arrays with Cm symmetry.
- Because of the geometric symmetry, the higher number m is, the fewer DNA tiles we need.
- In the thesis they show the 5*5 DNA arrays that have C2 symmetry and C4 symmetry
- In C2 symmetry, the array needs 13 tiles instead of 25 tiles.
- In C4 symmetry, the array needs 7 tiles instead of 25 tiles.
- In C4 symmetry, the array is composed of crosslike DNA tiles. A cross-shaped DNA tile has a flexibility under a stress.
- [from the thesis, DOI:10.1021/ja055614o]
- -The Ex. of C2 symmetry. Because of geometric symmetry, the array has the same DNA tiles in it in each a half round.
- what I felt
- -This strategy maybe could help to construct the larger fixed-size DNA Structure than ever before.
