American scientists have developed a program that automatically calculates the nucleotide sequences needed to create DNA structures of various shapes on a nanoscale, writes "Science Advances", quoted by BTA.

The program, called DNAxiS, was developed by specialists from Duke University and the University of Arizona.

Once the sequence is determined, DNA synthesis and assembly of the final structure begins.

The technology has been tested in experiments in which scientists have been able to obtain figures in the shape of a vase, a cup, a cone, a sphere and other structures with dimensions equal to thousandths of a millimeter.

According to experts, they can be used to create nano-sized containers for drug delivery or serve as molds for casting metal nanoparticles with complex configurations.

Scientists have identified DNA about 2 million years old

The development will help to create 3D structures much faster than specialists have been allowed to do by hand.

Currently, such mockups sometimes take years to complete.

According to the scientists, further development of the new program will help such DNA figures find a number of scientific and industrial applications.
