Hôm nay học Bionanotechnology, được Prof. giới thiệu bài này hay quá nên muốn giới thiệu lại với diễn đàn.
Mọi người đọc thử phần News trên Nature tóm tắt nha:
"...Rothemund has invented what he calls
'DNA origami', a method for building just about any two-dimensional pattern out of DNA molecules. His portfolio includes smiley faces, triangles, snowflakes and flowers.
Each item takes a month to plan and a few hours to make. All are made of a standard, single strand of viral DNA folded back and forth over rows of double helices in a template shape. The shape is maintained by DNA 'staples' - specially designed short strands - that stop the viral strand from unravelling.
Round the bend
First, Rothemund draws the shape on a piece of graph paper, and fills it with a single line. He describes the twists and turns of the line to his computer, which determines how many staples are needed and their chemical composition.
Then you send off for the DNA, says Rothemund. When it arrives, mix it together with a little salt, heat to near boiling and allow it to cool slowly. The DNA self-assembles into the required shape.
