Fabrication of self-replicating materials

Chemists, physicists working at the Center for Soft Materials Research, University of New York, USA said they have developed new materials with artificial structures that can be replicated. (This is a useful feature of new types of materials in the future). The results of this study were published in the journal Nature.

"This is the first step in creating artificial materials capable of self-replicating from an arbitrary component , " said Professor Paul Chaikin, who works at the Department of Physics, New York University (NYU). ), United States and co-author of the study.

The result of this study is the first step towards a common process for large-scale self-replication of a series of arbitrarily designed material particles, done in the order of DNA sequences. , just like the letters arranged to spell a specific word.

Scientists work at New York University (NYU), the United States believes them
It is possible to create materials that are self-replicating, based on new research.

The duplication process will help to keep the sequences and shapes of matter particles as well as the information needed to produce the next generation of materials.

In the natural world, DNA replication involves an additional combination of bases: adenine (A) combined with thymine (T); Guanine (G) combines with cytosine (C) to form its familiar twisted-pair chain. In contrast, New York University researchers have developed a form of artificial brick (a BTX sequence : material molecules are twisted three times, containing three DNA double helix with each BTX molecule. Includes 10 DNA strands).

Unlike DNA, BTX codes are not limited to 4 characters, in principle it can contain ten fifteen powers of letters and various artificial tiles using the complement of 4 single strands of DNA, or "sticky end" on each tile to form a bundle of 6 turns.

Professor Nadrian Seeman, working at New York University, USA told The Engineer that one of the strengths of this new technology is that DNA can be arranged at any cloning cycle with virtually no Any material in nano size (~ 20 nm).

Professor Nadrian Seeman works at the Department of Chemistry, New York University, and co-author of the study adds: Any material from metal nanoparticles or semiconductors, until Biological agents (DNAzymes or ribozymes or aptamers or enzymes or antibodies), or possibly polymer components, are in principle cloned together.
