Silver: a permanent bactericide
In the ancient Egyptian civilization, the god was considered to have the skin of gold and the bone of silver; in the Mayan civilization, the silver was called the "tear of the moon." Its beauty is so fascinating. For centuries, silver has been widely used in people's lives as currency, ornaments and even collections, and it is a symbol of identity and status. In addition, what secrets does Silver have?
In more than 300 BC, when the Greek Emperor Alexander led his army on the Eastern Expedition, he was infected with tropical dysentery. Most of the soldiers fell ill and died, and the Eastern Expedition was forced to end. However, the emperor and the officers rarely got sick. This mystery was not solved until modern times. It turned out that the tableware of the emperor and the officers were all made of silver, while the tableware of the soldiers were all made of tin.
The health care effect of silver has been recognized and applied since ancient times. After the human society entered the metal age from the Stone Age, people found that the water stored and carried with silverware was cleaner than the water in pottery or other containers, and would not deteriorate for a long time. According to Indian Buddhist scriptures, about 4,000 years ago, humans used copper pots to hold water. Later, the Mongolians discovered that silver containers for goat milk can preserve the freshness, and the effect is better than copper pots; silver can also be used to prevent wine and vinegar from deteriorating. ..... In addition to the use of silver for health care, people have also found that its compounds have healing effects on wounds. As early as 69 BC, the role of silver nitrate was recorded in the Roman Pharmacopoeia; in AD 89, Roman scholar Plinyd wrote in his book " It is written in "Natural History" that silver slag, as an ingredient in plasters, has a very high effect on wound healing.
However, due to historical and technological limitations, people did not know why silver had this function at that time. It was not until modern times that scientists have uncovered the mystery through painstaking research.
In 1893, Swiss botanist Megill measured that 0.101mg/L of silver ions can kill algae, and found that metal has a microdynamic effect on bacteria and microorganisms. After extensive testing, in most metals, silver has excellent antibiotic and sterilization effects.
Silver can form a small amount of positively charged silver ions in water. These silver ions can form strong bonds with substances used by microorganisms for respiration (such as molecules containing oxygen, sulfur, and nitrogen), so that these substances cannot It is used by microorganisms, causing them to suffocate and die; silver ions and compounds are toxic to certain bacteria, viruses, algae and fungi, and can weaken the enzymes that function in the body of the bacteria, thus preventing side effects and strengthening the tolerance of the bacteria , Fundamentally control the reproduction of germs. General antibiotics can only affect 6 kinds of germs on average, but silver can kill 650 kinds of germs. It is precisely because of its strong sterilization ability that silver is known as a "permanent fungicide".
In fact, the antibacterial properties of silver have been widely used in medicine as early as the 16th century. For example, silver sheets are used to cover wounds to prevent ulceration, silver yarns are woven into gauze to wrap skin wounds, and silver nitrate solution is dripped at birth to prevent mucosal infections. In the 1930s, the discovery of antibiotics made people neglect the use of silver's antibacterial properties. However, with the abuse of antibiotics and other chemical drugs, more and more microorganisms have developed drug resistance through mutation, making some diseases caused by drug-resistant bacteria incurable. At the same time, silver-based sterilization, which has the advantages of high efficiency, broad spectrum, and resistance to drug resistance, has once again attracted people's attention. At the same time, the development of modern nanotechnology has also opened up a broader space for the application of silver.
Nano silver applications are in the ascendant
Nano silver is the use of cutting-edge nanotechnology to nano-size silver. Studies have found that the smaller the silver particle size, the stronger its bactericidal performance. The emergence of nanotechnology has brought a qualitative leap in the bactericidal ability of silver in the nanometer state. Compared with silver, nano-silver has a higher surface area, surface effect, quantum size effect, etc., so the sterilization ability is greatly improved. Nano silver broad-spectrum sterilization does not have any drug resistance, can promote wound healing, cell growth and damaged cells repair, without any toxic reaction, and no irritation to the skin, which opens up the broad application of nano silver to antibacterial A broad prospect.
For example, the development of nano-silver antibacterial materials has opened up a new application space for its application in sanitary protection products. Its excellent antibacterial properties have led to great development of antibacterial textiles and non-textiles. Antibacterial masks, protective clothing, sheets, bedding, etc. are gradually being developed; in terms of medical surgical instruments, Shigejiro of Japan has borrowed its excellent antibacterial properties to manufacture stainless steel medical equipment containing nano-silver materials and have been widely promoted; In the case of scalds and burns skin grafts, nano-silver antibacterial dressings are used for treatment to promote wound healing and accelerate cell repair; the technology of combining nano-silver with molecular imaging has matured and is used in the early diagnosis and prognosis of cancer and tumors.. .... The clinical application of nano-silver has proved its relative safety to the human body, and the potential application value of nano-silver is being discovered bit by bit under the technical support.
Nano-silver antibacterial treatment can bring many benefits to consumers. For example, it can prevent the degradation of bacteria and prevent the discoloration of plastics; in textiles, it can prevent the reproduction of bacteria and better suppress the smell of clothing (such as sportswear) , Ultimately make consumers more comfortable to wear and extend their use time. In addition, reducing the frequency of washing can also save a lot of water and energy at low temperatures; in terms of disinfection, chemical irritation can be avoided, and the sterilization can be more thorough and longer..... .
Anhui Yinlizi Biotechnology Development Co., Ltd., a subsidiary of Wanyin Group, adheres to the concept of creating a "healthy, safe, and environmentally friendly" life for the majority of people. Based on silver itself, it relies on the research and development and application of high-end nano-silver technology and uses nano-silver, Silver ion technology is introduced into the production of consumer goods, and a series of daily chemical products with nano silver ions as the main ingredient have been developed, including nano silver mouthwash, nano silver toothpaste, nano silver car air purifier, nano silver antibacterial sanitary napkins, nano silver antibacterial There are more than ten kinds of anti-reverse osmosis diapers, nano-silver tableware disinfectant, and nano-silver high-efficiency broad-spectrum bactericide. The research and development results have obtained national invention patents.
With the improvement of living standards, people are paying more and more attention to healthy and safe lifestyles. Nano silver disinfection, which has excellent antibacterial properties, non-toxic, harmless, tasteless, non-irritating, and environmentally friendly, will undoubtedly replace traditional disinfection methods. Become a leader in the sterilization and disinfection industry. However, this is only the "tip of the iceberg" that silver shows to us. The world of silver is like an endless mine that continues to surprise us.
