Researcher found a new method for data storage in everyday objects, Living things have their instructions for installation and operation in the form of DNA. This does not happen with inanimate objects. If you want to print 3D objects, you also need a series of instructions.

Years later, if they decide to reprint the same object, they need access to original digital information. The object itself does not store print instructions.

Researchers have worked with Israeli scientists to develop a way to store comprehensive information in almost every location.

With this method, we can integrate 3D printing instructions into an object, so that after decades or even centuries, it will be possible to get these instructions from the object itself, researchers say.

Several developments in recent years have made this progress possible. One of them is the method of labeling Grass products with DNA barcodes embedded in mini glass beads. These nanowires have different applications; For example, to track geological tests or as a marker for high-quality food to distinguish them from fake ones.

Barcodes are short only 100-bit codes (100 digits with “0” or “1”). This technology was commercialized by the ETH of Helix spinoff.

At the same time, it is possible to store large amounts of data in DNA.

Researchers developed a method that stored 215,000 terabytes of data in one gram of DNA. And Grass itself has managed to store all music albums in DNA which is equal to 15 megabytes of data.

As an application, 3D researchers print plastic rabbits containing instructions (about 100 kilobytes of data) to print objects. The researchers did this by adding tiny glass beads that contained DNA to the plastic.

And as in biology, this new technology method stores information for generations, a feature that scientists show by extracting print instructions from a small rabbit and using them to print new ones.

The researchers used technology to store short films from this archive (1.4 megabytes) in glass beads, which were then poured into ordinary eyeglass lenses.

There will be no problem to carry such glasses through airport security so that it is not detected to transport information from one place to another.

At present, the process is still expensive. Translations of 3D printed files, such as those stored in plastic rabbit DNA, are worth around 2,000 francs, Grass said.

Most of it flows to the synthesis of appropriate DNA molecules. The larger the item, the lower the unit price.
