colloidal silver nanoparticles | Various types of nanoparticles on sale

Bacterial resistance to antibiotics has increased the importance of developing new antibacterial agents. colloidal silver nanoparticles can be considered as one of the important antibacterial agents. Given the environmental concerns about expanding the use of silver nanoparticles, the use of green methods to synthesize these nanoparticles can also lead to the development of nanoparticles with superior properties.

How do silver nanoparticles kill bacteria?

The history of silver nanoparticles goes back to year 1889. There are many silver nanoparticles research paper. The use of bio-compounds, especially plant extracts, instead of toxic and hazardous chemicals for the silver nanoparticles synthesis can be a way to reduce the environmental concerns of these nanoparticles. Due to the remarkable antibacterial properties of nanoparticles synthesized by this method, they can be used for various medical, pharmaceutical, food and industrial applications.

bacterias

All bacteria use the enzyme as “chemical pulmonary” for oxygen metabolism. Silver ions paralyze the enzyme and stop the absorption of oxygen. It effectively strangles any bacterium and kills it within 6 minutes, leaving the tissue and surrounding material unaffected.

viruses

Viruses grow by taking another living cell and reprogramming the nucleus to replicate the virus instead of the healthy cell. As part of this process, the cell returns to a more primitive form that relies on an elementary form of oxygen metabolism enzyme as a chemical lung. Again, the silver ions stop when oxygen enters the virus cell and dies of suffocation.

What can silver nanoparticles be used for?

• Silver nanoparticles are clusters of silver atoms up to 3 nm in size and are widely used in various fields due to their unique physical and chemical properties.
•  In addition to their use in the engineering industry (such as catalysts, optical devices, and electronics applications), these nanoparticles are also used in areas such as disinfectants, textiles, and medical devices due to their excellent antibacterial activity.
•  Silver nanoparticles exhibit a wide range of antibacterial activity. The antiviral effect of these nanoparticles has also been reported in the articles. Studies have shown that silver nanoparticles prevent the spread of HIV / AIDS and their effects are far greater than those of gold nanoparticles. The effect of nanoparticles on viruses such as herpes and hepatitis B has also been reported.
•  One of application of silver nanoparticles is to help heal wounds, as increased resistance of the microorganisms to antisera can delay wound healing. In general, injuries such as cuts, abrasions, burns, pimples, warts, fungal diseases, and other skin diseases can be treated with silver nanoparticles.
• Silver nanoparticles have been found to increase the efficiency of antisera. Nowadays, artificial bones made of polymethylmethacrylate and nano-silver are of medical application.

Is colloidal silver a nanoparticle?

Colloidal silver is an aqueous solution of silver (+ Ag) ions that is suspended by the electric charge of each of the silver particles. Colloidal silver acts as a potent antiseptic agent. For example, if a typical antibiotic kills bacteria, colloidal silver will more effectively kill the two types of disease agents. The presence of colloidal silver ions results in the repair of damaged tissues, destruction of old or cancerous cells, as well as normalization of living organisms under pathological conditions.

Formation Mechanism of Colloidal Silver Nanoparticles

• Silver colloidal ion particles are highly permeable to the pathogens due to their extremely small size. Therefore, their ability to infiltrate viruses, bacteria and fungi significantly increases their destructive effect.
• The use of silver in the form of ion particles allows it to increase up to three times the contact surface of silver. Studies have shown that the size and shape of silver particles affect their antibacterial properties.
• Research in this field has awakened medical science about the extraordinary ability of silver (in the form of silver ions or other nano-sized substances) to eliminate infections, while extensive research has been carried out in Russia for a long time. And it has always been used in the treatment of diseases.
• In fact less medicine in Russia can be found that is unaware of the ability of silver colloids. The effect of silver ions, such as antibiotics, is not only limited to infection, but also stabilizes cell structure.
• In other words, the presence of colloidal silver along with viruses, fungi and bacteria, or any other single cell pathogen, inactivates its oxygen fuel enzyme, causing the pathogen to “disappear” after a few minutes and die. It then gets out of the body with the help of the immune system, the lymph nodes and the extrinsic system (intestine, skin, kidney, lung and liver).
