Scientists’ New Technique introduced with Lego-like DNA 'bricks'

The newly created technique by the researchers at Harvard's Wyss Institute is being believed to open a good way for nanoscale medical and electronic devices as the experts have been able to create a 100 three-dimensional (3D) nanostructure with the help of DNA building blocks that function very much like Legor bricks, advanced form of the two-dimensional (2D) structures that were announced a few months ago by the same team in Nature.

More details about the recent research of the Wyss team have been reported in Science Magazine's November 30 cover story.

Working under the guidance of Wyss faculty member Mr. Brian Wei, Ph. D., the Wyss team of researchers was some time earlier also in news for its nanofabrication technique, i. e. DNA-brick self-assembly, which is basically a method of building complex nanostructures out of short synthetic strands of DNA, that it previously described.

According to expert's explanation, under the new technique, the single-stranded tiles (SSTs) or 42-base strands of DNA "building blocks," that are like Legos, could be programmed thereby efficiently assembling them into precisely designed shapes like that of letters and emoticons etc.

"This is a simple, versatile and robust method", the study's senior author, Mr. Peng Yin, said in a news release.
