DNA bar codes are anti-goods

In an effort to eliminate low-quality or disguised electronics, the US Department of Defense began applying DNA barcodes to track the origin of the device.

Next month, electronic components sold to the US military will be attached to a piece of artificial DNA, to eliminate the possibility of being exchanged for bad devices. The Pentagon is having a headache about swapping fake components, because those chips will be equipped for fighter, helicopters or night-vision infrared glasses, which means the need for extreme precision. If the circuit does not work, the aircraft cannot take off; Worse, operating in a critical condition can malfunction at any time. The report of the US Senate Military Commission in November 2011 revealed 1,800 suspicious components were detected. Since then, the US Congress has been fiercely questioning military contractors about their supply system.

DNA barcode technology helps tighten defense security in the United States

According to Fox News, Applied ADN Sciences in New York has partnered with the Logistics Department of the Ministry of Defense to come up with an initial solution that only applies to textiles: DNA implants. The DNA fragment is mixed in ink and printed directly onto the chip. Normally ink is in the invisible state, they only appear under laser light, just like stealth tagging on each item. Not stopping there, these DNA tags cannot be copied, ensuring that the components come from the right factory. The reason why bad guys are hard to mimic the original DNA code is that the gene fragments are very complicated.

DNA is made up of four different molecules: adenine, guanine, cytosine and thymine. They can only connect in pairs, called base pairs, written into GC or AT. Base pairs line up to form the double helix of DNA. To decode DNA, first magnify the entire gene segment, by dissolving it into the solution and then adding chemicals to stimulate them to copy themselves. In a living organism, DNA fragments are made up of certain patterns, and the arrangement of GC - AT molecular structures is not accidental. When they have formed a chain, a scientist can determine their order. From there, this person will indicate which protein is encoded.

Applied ADN Sciences took base pairs and combined them in random order. In the hands of enough partners, the company can offer millions of different combinations, according to Karim Berrada, Applied ADN Sciences' DNA Formulas. The number of combinations is quite large, although only based on a small group of base pairs. For each A, G, C or T, there were 4 combinational possibilities, so a sequence of 10 pairs also had more than 1 million results. If a person wants to decode the DNA fragment on a chip without knowing the exact structure of the base pairs, the results will never match the original, according to Applied ADN Sciences experts. And so, they eliminated the possibility of being swapped.

In addition to defense, new technology opens up potential applications for the global security market, worth up to $ 85 billion a year. GeneWork in Australia is waiting for a patent on the technology before it can be deployed for commercial purposes. DNA bar code technology can be applied to paper money, alcohol, pharmaceuticals, computer chips, artworks and even to real people in case of monitoring the members of organized crime groups. , according to The Adelaide Now.
