Modern nanotechnology has changed people's traditional perception of silver. Nanotechnology is an emerging technology that developed rapidly in the early 1990s. Nano is also called nanometer, and 1 nanometer is equal to ^10-6 meters. Nanosilver is nanotechnology through nanotechnology. Studies have shown that adding 1-3 mg (1 g = 1000 mg) of nanosilver to 1 kg of water kills all harmful bacteria.

The Chinese medicine classic "Compendium of Materia Medica" has such a record on silver: silver has five internal organs, peace of mind, stop convulsions, and evil spirits. The ancients not only used silverware, but also applied fine silver or thin silver foil to the wound for anti-inflammatory. Silver can be sterilized and anti-inflammatory, which is the cognition of the ancients in the practice of long-term life. So what is the nano-silver, what are the advantages and effects of nano-silver, why nano-silver has such excellent bactericidal effect, CCTV found the journey "Health Camp" for you to interpret the mystery of "nano-silver"!

Unlike traditional antibiotics, nanosilver is a safe and environmentally friendly natural fungicide. Its sterilization mechanism is:

Lead to the deformation of the molecular structure of the bacteria DAN, so that the bacteria are inactivated.

Combined with cell membrane and cell wall DAN, it replaces the hydrogen bond between thymine and purine, cytosine and guanine in the double helix structure of DAN molecule, which leads to the structural deformation of bacterial DAN, inhibits the synthesis of DAN, RNA and protein, and causes the loss of pathogens. live.

Unique chemical structure, thorough sterilization:

The chemical structure of silver determines the high catalytic ability of silver. The high oxidation state of silver has a high reduction potential, which is enough to generate atomic oxygen in the surrounding space. The atomic oxygen has strong oxidizing properties and can be sterilized.

Binding to the thiol group (-SH) binds the thiol group (-SH) on the protease, deactivating the protease and causing bacterial death. When the bacteria are killed, the silver ions are released from the bacteria, and then contact with other bacteria, and the above process is repeated. This is also the reason for the persistence of silver sterilization.

Promote tissue repair and regeneration:

Promote tissue repair and regeneration. In slow-strain injury, the activity of metalloproteinase (MMP) in wounds is enhanced. The MMP structure contains sulfhydryl (-SH), and the activity requires the participation of zinc ions. Excessive MMP activity can destroy growth factors and new tissue, hinder healing. Silver can be combined with sulfhydryl groups in the MMP structure, or by reducing zinc ions on the wound surface, thereby reducing the transitional MMP activity and promoting tissue repair and regeneration.

safety:

As early as the Ming Dynasty, China’s "Compendium of Materia Medica" also contained records of "raw silver, spicy, cold, and non-toxic". Li Shizhen said, "The silver is non-toxic, and its poison is also poisonous."

The safety of nanosilver is recognized by the international medical community. In the United States, the safety of nanosilver is considered to be the same level as food. 　

In 2001, Robert H. Demling, a professor of surgery at Harvard Medical School, published an article in WOUNDS on the efficacy of silver in treating wounds. He believes that "silver blocks the microbial respiratory enzyme system (blocking its energy production). To kill microbes, but no negative impact on human cells... The use of silver over the centuries has proved that silver is non-toxic to human tissue!

In 1990, the US Toxicology and Disease Registry and the US Public Health Agency commissioned Clement International to conduct a silver toxicity investigation involving the absorption, distribution, metabolism, excretion, and health effects of silver. According to the study, there is still no Because of the human toxicity caused by silver or affecting the function of the immune system, cardiovascular system, reproductive system, and developmental and genotoxicity.

More than 100 years of clinical and laboratory research has proven that silver is very safe.

The safety of nanosilver is recognized by the international medical community. In the United States, the safety of nanosilver is considered to be the same level as food.
