What is silver nanoparticle?
Nano particles are 1-100 nm in size. Nanotechnology is a technology determined by particle size, covering diverse scientific fields such as surface science, organic chemistry, molecular biology, semiconductor physics, energy storage, engineering, micro fabrication, molecular engineering … Silver nanoparticle are silver particles with the size 1-100 nm. In addition to the antibacterial ability through the release of Ag + ions, silver particles at 1-10nm nanoscale can directly affect the cell membrane of bacteria by altering the osmotic pressure. cell membranes of bacteria, resulting in cell death.

Silver nanoparticle act as antibacterial and antifungal agents for industrial purposes, water treatment and in consumer products (such as clothing, cosmetics, baby care items, containers food, antibacterial drugs for humans, veterinary medicine, aquatic products … many others).
Not only effective in the field of disinfection, nanoscale silver is also known to be an excellent catalyst for many chemical reactions. Organic fusion in particular has grown rapidly over the years, thanks to its unique properties such as selectivity, catalytic durability and its reusability in reactions. chemistry. Thus, silver nanoparticles have been exploited for a wide range of capacities, such as the reduction reactions of nitro ring compounds, carbonyl compounds, and deminization. Especially its applicability in industry, because pharmaceutical industries have produced the famous water pollutant 4-nitrophenol, which is a serious environmental pollutant. Therefore, there are many reports on the use of nano-silver as catalyst for 4-nitrophenol reduction in water and many related kinetic studies. From an organic synthesis perspective, this reaction is quite simple and represents many similar organic fusion reactions.
Is silver nanoparticles harmful?
A lot of misinformation has been published in the media claiming that silver nanoparticles have not been tested for safety and it is not known what effects the products may cause to humans or the lips. school. It has also been claimed that these silver products can cause heavy metal poisoning. This attack on nano-silver is very little, if any, and more important, it is the work of other people or special interest groups by restricting the freedom to own and use the products. safety of a person. The US Biotechnology Laboratory has spent millions of dollars testing the safety and efficacy of silver nanotechnology products.
The US Biotechnology Laboratory has been licensed for two of their ASAP silver nanoparticle products from the EPA, after completing thousands of antibacterial tests that meet EPA’s stringent guidelines. Those products have a 10-minute kill time claim for both home and hospital disinfection against deadly pathogens like staph, yeast and black mold, etc. These products are also approved to disinfect dental waterways used for spraying into the human mouth, as well as for home and industrial heating and ventilation.
Each EPA approved product is required to have safety information, and according to that information, the EPA’s need to print a toxic spill or reportable spill in the product’s MSDS (Material Safety Data Sheet Whether). For example, a chlorine-type cleaning product (found to be publicly purchased on store shelves right now) has a toxic spill rating of about 3 gallons, meaning spills of 3 gallons or more must be reported. reported to EPA and processed by HAZMAT. Meanwhile, the 32 ppm nano silver product of the American Laboratory had a toxic spill level of 12,500,000 gallons (equivalent to 3 million liters of nano silver 500 ppm and 1.5 million liters of 1000 ppm). One tanker will hold approximately 1 million gallons, which means that 12.5 tankers filled with ASAP nano-silver disinfectant will have to dump their entire product together to be considered a hazardous event. environment. The management of American Biotech Labs believes that no large enough tank or container worldwide can hold and then spill enough ASAP disinfectant product to actually report a poison spill. into the environment.
