A team of scientists at the University of California San Diego have recently developed a high resolution design of a nano-scale square fabricated from ribonucleic acid, or RNA.
UCSD's Self Assembling Nano Square
The design featured in a paper published recently in an online issue of the journal Proceedings of the National Academy of Sciences has been authored by a group of scientists led by Thomas Hermann, who is an assistant professor of chemistry and biochemistry at UCSD.
According to the team, the genetic code of the RNA allows it to transmit structural data programmed in the building block series. The sequence programmed into the RNA helps it to develop four corners, and forces the four corners thus formed to independently form the nano-square.
According to Hermann, the RNA square can be used in the form of a nano platform that auto assembles for the programmed grouping of molecular bodies connected to the corner components.
