How strong is the bactericidal action of nano silver

What is the role of nano silver?
Nano silver is composed of silver nanoparticles. These particles are used as antibacterial and antifungal agents in industrial applications, water treatment and consumer products (such as clothing, cosmetics, childcare products, food containers, and many other products). The concept of nanosilver is silver elemental silver with a particle size of nanometer level. Nano silver is a powdery silver element with a particle size of less than 100nm, generally between 25-50nm. The performance of nano silver is directly related to its particle size. The study found that the smaller the particle size, the stronger the sterilization performance.
Is nano silver the same as colloidal silver?

First, the colloidal silver particles are prepared without a capping agent. On the other hand, silver nanoparticles are covered with plant extracts. This makes them more stable and non-toxic to human tissues. In addition, with the advancement of technology, the size of nanoparticles has become more consistent.
Does nano silver kill bacteria?
Silver is a well-documented antibacterial agent that has been shown to kill bacteria, fungi and certain viruses. The antimicrobial effect is the positively charged silver ions (Ag +)22,22. Silver ions target microorganisms through several different modes of action.
Nano silver cannot be observed with the naked eye. A very small amount of nano silver is introduced into deionized water to form a colloidal solution-nano silver antibacterial liquid. Its particle size is 500 to 1000 times smaller than that of cells, it is easily absorbed and excreted, and it can quickly and effectively catch-all single bacteria, fungi, and viruses. It is different from general antibiotics. Antibiotics can only kill a few bacteria but not viruses. Nano-silver can kill more than 650 kinds of bacteria and viruses. It is well-deserved as the second "immune system" of the human body.
Is Nano Silver healthy?
As a compound, silver found in the environment is considered quite safe. However, people do not know enough about the environmental and health risks of silver nanoparticles, so ingestion of colloidal silver is considered unsafe.
Nano silver antibacterial Compared with other biological and chemical disinfectants, nano silver can kill more than 650 kinds of bacteria in a few minutes, broad-spectrum sterilization without any drug resistance, and can promote wound healing, cell growth and damage. The repair of cells has no toxic reaction and no irritation to the skin. This opens up broad prospects for the widespread application of nano silver to antibacterial. It is the latest generation of natural antibacterial agents.

Is nano silver dangerous?
Nano silver may cause slight eye and skin irritation. It can also act as a mild skin allergen. Inhalation of silver nanoparticles mainly affects the lungs and liver. It has been demonstrated that silver nanoparticles may be genotoxic to mammalian cells.
Features of Nano Silver
1. An antibiotic can kill about 6 kinds of pathogens, while nano silver can kill hundreds of pathogenic microorganisms.
2. Nano silver can kill more than 650 kinds of bacteria in a few minutes. The unique bactericidal mechanism enables nano silver particles to quickly kill pathogenic bacteria at low concentrations.
3. Nano silver particles have super permeability, can quickly penetrate 2mm under the skin to sterilize, and have a good sterilizing effect on common bacteria, stubborn bacteria, drug-resistant bacteria and deep tissue infections caused by fungi.
4. Promote wound healing, repair and regeneration of damaged cells, decompose muscle growth, antibacterial and anti-inflammatory, accelerate wound healing and reduce scar formation.
5. Nano silver particles are produced using patented technology, with a protective film outside, which can be gradually released in the human body, so the antibacterial effect is lasting and stable.
6. Nano silver is a non-antibacterial bactericide: Nano silver can kill various pathogenic microorganisms and is stronger than antibiotics. The unique antibacterial mechanism of 10nm nano silver particles can quickly and directly kill bacteria, causing them to lose their reproductive capacity and cannot be produced. The next generation of drug resistance can effectively avoid repeated attacks caused by drug resistance.
Nano silver antibacterial mechanism
1. Nano silver particles are between macroscopic substances and microscopic atoms and molecules, exhibiting special surface effects, small size effects, quantum size effects and macroscopic quantum tunnel effects, and can easily enter pathogens;
2. The size of nano silver particles is small, and the volume percentage of the surface is large. The bonding state and electronic state of the surface are different from the inside of the particle. Incomplete coordination of surface atoms leads to an increase in active sites on the surface, which has the basic conditions as an antibacterial agent;
3. Nano-silver has strong penetrating power, can fully and fully contact and attack pathogens, thereby exerting stronger biological effects. It has the advantages of high safety, wide antibacterial range and long-lasting sterilization time. The antibacterial properties of nanosilver are far more effective in killing pathogenic bacilli, cocci and filamentous fungi than traditional silver ion fungicides. Nano silver particles can kill bacteria, fungi, mycoplasma, chlamydia and other pathogenic microorganisms.

The U.S. Department of Justice announced that it would stop selling "nanosilver" products to treat Covid-19
In a permanent injunction civil lawsuit filed in the U.S. District Court of New Jersey on November 13, 2020, the U.S. accused Natural Solutions Foundation, Dr. Rima Laibow and Ralph Fucetola of selling and distributing a nanosilver product. The defendant claimed that it could cure and relieve Treat or prevent COVID-19. The defendant's nanosilver product allegedly contained silver particles in the solution. According to government complaints, qualified experts generally do not believe that nanosilver is safe and effective for the uses advocated by the defendant.
The Acting Assistant Attorney General of the Department of Justice and Civil Affairs Jeffrey Bossett Clark said: "The Department of Justice does not allow individuals to sell unproven, unapproved drugs to take advantage of an ongoing public health emergency." "We will continue to work closely with the Food and Drug Administration to stop illegal sales of such products during this pandemic."
Trial attorney Brianna M. Gardner of the Consumer Protection Division of the Civil Litigation Division of the Department of Justice and David Dauenheimer, Deputy Director of the Government Fraud Division of the U.S. Attorney's Office for the District of New Jersey, will prosecute law enforcement actions with the assistance of the Federal Bar Association. FDA Chief Executive Counsel Jaclyn Martínez Reply, Office of the General Counsel, Department of Health and Human Services.

The allegations in the complaint allege that if the case is to continue, the government must prove that it has received a permanent injunction against the defendant.
