The hottest South Korea has successfully developed

  • Detail

South Korea has successfully developed a DNA bar code recognition system recently.

the research led by Professor Cui Zhenhao (translation) of the Department of chemistry, Seoul University, South Korea, has high precision and repeatability; The test team, which can be used to stop the stretching, tightening, bending, shearing and peeling of various materials according to relevant national or international specifications, recently announced that a nano DNA barcode system has been successfully developed, which can greatly improve the reliability of product barcode identification

because the DNA bar code cannot be recognized by the naked eye and is difficult to tamper with, it can prevent possible counterfeiting during the transportation, circulation and sales of products. Professor Cui said, His research team "The application of nanotechnology to DNA bar code has successfully developed a new bar code system with greatly improved stability and reliability, which is the first in the world. Take green agricultural products that may be confused in the circulation process as an example. If farmers use spray to spray nano particles on agricultural products, it will be difficult for illegal businessmen to do tricks in the circulation process, and the quality of products can be guaranteed."

dna bar code system attaches DNA particles with certain specific information made of high-grade stainless steel in the cold and hot impact testing machine to the product. When it is necessary to identify the product, the information is interpreted through the DNA decoding machine. At present, the interpretation process of DNA bar code has a certain complexity, but countries around the world are actively developing chips that store all kinds of DNA information, which will greatly shorten the interpretation time and reduce the cost exponentially

dna bar code has a wide range of applications, which can be widely used in industrial and agricultural products that need to be accurately tracked, and even can be used to track the diffusion process of pollutants. In early May 2003, the U.S. Department of Commerce announced that it would adopt the DNA textile marking system of applied DNA Science in recent years as one of the three main means for textile manufacturers and customs to mark and identify textiles
