DNA anti-counterfeiting technology is one of biological anti-counterfeiting. Like other biological anti-counterfeiting technologies, the DNA anti-counterfeiting technology is also a high-tech biological anti-counterfeit technology that is being “heat-fried†at present, and is increasingly used in the anti-counterfeiting of commodities.
1 What is DNA technology
DNA anti-counterfeiting is based on the principle that the DNA of different individuals has different coding structures, so that the anti-counterfeiting label contains DNA of a certain individual and can be stored for a long time under normal conditions. In practical applications, if the DNA can be detected in the label (that is, the detected DNA is "identical" to the identified individual), it is true that the detected DNA is false. Among them, an individual may be either a person or an animal, or it may be a plant or a microorganism. Even such DNA may be entirely artificial. In actual production applications, the large amount of DNA material used to manufacture the anti-counterfeit labels is not directly derived from an individual. Only a sample of DNA extracted from an individual can be replicated in large numbers using biological methods.
2 DNA anti-counterfeiting technology features and advantages
1) The DNA sequence is from A. T. G. C Biomolecules with four bases randomly arranged can be used for product anti-counterfeiting. As a password indicator, as long as this password logo is applied to a protected object, a biological symbol of a non-biological product can be given. This sign can be dominant, or it can be made implicit to achieve the corresponding anti-counterfeiting effect.
2) DNA anti-counterfeiting technology has a high degree of confidentiality and uniqueness, and it is temporarily impossible to counterfeit. Because the current stage of biotechnology is still unable to accurately synthesize DNA molecule sequences of the same length, and the concentration of DNA mixed into the medium is extremely low, it is impossible to know the sequence of the inserted DNA and the size of its molecular weight. Therefore, confidentiality and uniqueness are extremely high.
3) Long shelf life, protected DNA can be stored in normal light for more than 100 years.
4) Application simplicity. The key to the application of DNA anti-counterfeiting technology lies in its combination with various media. The medium containing the DNA fragments is produced according to the usual production process. The products from the terminal are combined with the anti-counterfeiting performance in the most natural way.
5) National courts can provide legal evidence. In forensic science, DNA testing can be the ultimate proof of the identity of a person. The detection of commercial DNA fragments provided by the same principles and similar methods of identification can also serve as the ultimate evidence accepted by the court.
3 DNA anti-counterfeiting technology in packaging printing anti-counterfeiting application
1) Recessive DNA anti-counterfeiting inks The hidden DNA anti-counterfeit inks are genetically engineered and treated with a combination of DNA anti-counterfeit inks and general printing inks that are uniformly mixed at a fixed ratio to produce a variety of printing inks. Products. Since the DNA is so tiny that it cannot be observed with the naked eye, the hidden DNA security ink can be used as a hidden security weapon. The manufacturer can not declare it to the public. It is only used as a basis for protecting the rights of the legitimate manufacturers when there is legal dispute. When authenticity is to be verified, only a small amount of ink needs to be scraped to detect the authenticity of the DNA security ink using a proprietary device.
Recessive DNA security inks have a wide range of applications and are suitable for a variety of printing methods, such as gravure. Letterpress. Flexo. Screen printing and so on. Mainly used in trademarks. secret document. Chip surface identification. Securities. Lottery ticket. stamp. Customs stickers. ID cards and pharmaceutical packaging printing and other fields.
2) Edible DNA security ink
The edible DNA security ink is a mixture of replicated DNA and edible ink. The DNA anti-counterfeit ink is safe in performance and will not cause any harm to the human body. The DNA anti-counterfeiting ink can be printed on medicines such as capsules or medicine ingots, and the authenticity of the DNA anti-counterfeit ink can be identified only by checking the DNA code mark on the capsule during authentication.
When it is necessary to check whether the drug is a fake drug, it is only necessary to scrape the ink from the printed words of the capsule or the tablet to perform DNA extraction. Purification and validation of DNA code markers can verify the authenticity of the drug. The edible DNA security printing ink effectively combines the anti-counterfeiting mechanism with the product and reaches the highest level of anti-counterfeiting realm.
Edible DNA security inks are mainly used in the pharmaceutical industry, such as capsules. Film ingots. Graphic printing of sugar-coated tablets.
3) Dominant DNA security ink
Dominant DNA anti-counterfeit inks are also made by uniformly mixing DNA code markers with special inks, and utilize high-level bio-chromic reactions. Instantaneous energy conversion and release system, so that the dominant DNA anti-counterfeit ink has an immediate recognition function.
When the dominant DNA anti-counterfeiting inks are tested, they need to be coated on the ink surface with an identification rod with a driving buffer. The DNA blue ink that contacts the driving buffer will be changed by the high-energy excitation of the buffer, and its color will change. From the cold color (blue) to the warm color (pink) instantaneously, and counteracts the high energy of the driving fluid in a few seconds to restore the original shape. The anti-counterfeiting label is restored from the warm color system to the cool color system, and thus has the function of immediate color change and restoration. Can help consumers easily distinguish between authenticity before buying.
4) DNA anti-counterfeit labels
DNA anti-counterfeiting label is a comprehensive anti-counterfeiting scheme for DNA technology. It is made up of dominant DNA anti-counterfeiting inks and supplemented with other multiple anti-counterfeiting technologies. It not only has the characteristics of immediate identification of dominant DNA inks, but also includes anti-counterfeit printing of various banknotes. In order to increase the added value of the comprehensive anti-counterfeiting scheme, the company can use special detection instruments to analyze and compare the DNA cryptographic markers in the ink and provide users with ultimate legal protection.
The design of modern DNA anti-counterfeiting labels is basically as follows:
1DNA security ink: contains unique. Hard to copy DNA sequences;
2 Fluorescent printing: The identification mark of a company printed with fluorescent ink must be identified by means of a counterfeit banknote;
3 Anti-counterfeiting shading: DNA is hidden in the shading, which can prevent the printing plate copy;
4 Microtext: Consisting of continuous DNA microtexts that need to be seen with a magnifying glass to avoid color scans. copy;
5 tear-proof design: strong adhesive and die design, to avoid repeated application.
Detection method (mainly detecting dominant DNA anti-counterfeit ink): Using the identification stick attached to the product, you can immediately identify the authenticity. The detection method is the same as that of the dominant DNA security ink. Other anti-counterfeiting methods are detected using the corresponding detection methods.
Application: For all kinds of products, such as electronic communication products. machine part. Electrical products and cigarettes. Labels for high-end products such as famous wines.
4 Summary
DNA anti-counterfeiting technology has gradually entered its business. At the Sydney 2000 Olympic Games in Australia, DNA samples of famous athletes' oral mucosal epithelial cells were extracted, a specific piece was cut from them, and their genetic code was copied in large numbers and protected with proteins. Mixed in dyes, dyed fabrics with the dye to produce the 2000 Olympic Games logo. Anti-fake label. Checking the DNA code with a special scanner can verify the authenticity.
It is believed that in the future, as the requirements for the anti-counterfeiting performance of commodities continue to increase, DNA anti-counterfeiting technology will exert its unique charm and will occupy a place in the anti-counterfeiting market. We also believe that DNA anti-counterfeiting technology will bring convenience to our lives and contribute to fighting counterfeit products.
