New Nanotechnology build DNA structures.

[ecoli]

Using brand-new procedures, researchers cooperating from Universities in the US and the UK, have used a new, simple procedure to build pyramidal structures out of DNA.

 

 

The new technique is said to built trillions of these components in only several minutes. This pyramidal structures are very sturdy, and are only 10 nanometers wide, making them ideal for using as the building blocks of nanostructures, such as 3-d electrical circuits.

First, trillions of 4 distinct single stranded DNA molecule are placed in salt water, and the mixture is heated, and then rapidly cooled - that is the entire procedure.

Researchers have also succeeded in linking several of the structures together.
