Nanometer (nm) is the second smallest micron unit of measurement, a nanometer is a millionth millimeter, namely nanometer, which is one billionth of a meter. Nano-silver, nano-technology is the use of cutting-edge nano silver, nano technology appears, the silver in the nano state sterilization ability to produce a qualitative leap, little nano silver may have a strong bactericidal effect, can kill in minutes Death 650 kinds of bacteria, broad-spectrum bactericidal without any resistance, can promote wound healing, cell growth and repair of damaged cells without any toxicity, skin irritation also did not find any, which gives wide Application to antibacterial nano silver has opened up broad prospects, is the latest generation of natural antibacterial agent, nano-silver sterilization has the following characteristics:
Broad-spectrum antibiotic
Silver nanoparticles directly into the cell and oxygen metabolizing enzymes (-SH) combine to make a unique cell suffocated mechanism of action, can kill most bacteria in contact with, fungi, mold spores and other microorganisms. After eight domestic authorities found: their drug-resistant pathogens, such as E. coli, resistant Staphylococcus aureus, resistant Pseudomonas aeruginosa, Streptococcus pyogenes resistant enterococci, anaerobic bacteria, which are full of antibacterial activity; surface burns and trauma of common bacteria such as Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans and other G +, G- pathogens have a bactericidal effect; Chlamydia trachomatis, a sexually transmitted disease caused by Neisseria gonorrhoeae also has a strong bactericidal effect.
An antibiotic can kill about six kinds of pathogens, and antibacterial coating nano silver can kill hundreds of pathogenic microorganisms. Kill bacteria, fungi, trichomonas, branch / chlamydia, gonorrhea, strong bactericidal effect of antibiotic resistant bacteria have the same role in the killing!
Potent bactericidal
It found, Ag 650 kinds of bacteria can kill within minutes. Nano silver particles and pathogens in the cell wall / membrane-bound, directly into the cell and quickly combine with oxygen metabolizing enzyme sulfhydryl (-SH), inactivating the enzyme, blocking the respiratory metabolism to suffocate it. Unique sterilization mechanism, making silver nanoparticles at low concentrations can rapidly kill pathogens.
Permeable
Silver nanoparticles with superior permeability, can rapidly penetrate the subcutaneous 2mm sterilization, for common bacteria, stubborn bacteria, resistant bacteria as well as the deeper tissue infections caused by fungi have a good bactericidal effect.
Repair and regeneration
Nano-silver can promote wound healing, promoting repair and regeneration of damaged cells, to rot myogenic, anti-bacterial anti-inflammatory improve microcirculation trauma to surrounding tissue, effectively activate and promote the growth of tissue cells, accelerate wound healing and reduce scarring generated.
Antibacterial lasting
Silver nanoparticles utilizing patented technology, outer layer of protective film can be gradually released in the human body, so the antibacterial effect.
No drug resistance
Nano-silver is a non-antibiotic agents: nano-silver can kill a variety of pathogenic microorganisms, stronger than antibiotics, antibacterial mechanism of silver nanoparticles unique 10nm size can quickly kill bacteria directly to the loss of reproductive capacity, and therefore, can not produce the next generation of drug resistance, and can effectively avoid drug resistance and cause recurrent permanently.
Silver applications in modern medicine
In 1884, the German obstetrician F. Crede (Claude), the concentration of 1% silver nitrate solution was dropped in the eyes of newborns to prevent blindness caused by neonatal conjunctivitis, the incidence of infant blindness dropped from 10% 0.2 percent, until today, many countries still using Crede prophylaxis.
In 1893, C. Von Nageli (Nag column) through a systematic study, first reported in the metal (especially silver) bacteria and other lower organisms lethal effect, so there may be a silver disinfectant. Since then, the use of silver into the modern era.
Silver in various forms used in modern medicine, comprising:
(1)silver: 0.5% silver nitrate standard solution for treating burns and wounds; 10-20% silver nitrate solution applied, it can be used for the treatment of cervical erosion.
(2)Silver sulfadiazine: Columbia University Charles L. Fox (Fox) professor and sulfadiazine silver compound, silver sulfadiazine produced its activity than the individual sulfa strong activity at least 50 times. 1968, silver sulfadiazine (Sulfadiazine Silver) introduced to the market, because of its variety of bacteria, fungi and efficient role in the killing has, naturally, painless way to completely repair the wound site without skin grafting, has become the treatment of trauma ( such as burns) important drugs. It has now been included in the national basic medical insurance drug list.
(3)colloidal silver or silver protein: an effective topical anti-infective substances, colloidal silver can be used for gynecological sterilization.
(4) silver plated materials: silver, founder of the research, AB Flick (Fleck), Dr. Silver has developed a product that is coated with a layer of silver on a bandage, used as a dressing. Inspired by him, people use silver antimicrobial resistance, have developed a silver-plated sutures, silver catheter. Currently the United States has a dozen silver-containing products, listed as a medical device to obtain FDA approval, including silver dressings, silver gelatin, silver powder and other types of medical products.
