The application of magnesium oxide nanoparticles in biocides is mainly based on their unique physical and chemical properties, especially their powerful oxidizing ability and disruptive effect on bacterial cell membranes. The following are a few key points for the application of nano magnesium oxide as a biocide:
Strong oxidizing properties:
The reactive oxygen ions generated on the surface of nano-magnesium oxide are strongly oxidizing, which can rapidly oxidize and destroy the cell membrane and cell wall structure of bacteria, leading to bacterial death. This mechanism of action is effective against a variety of bacteria such as Escherichia coli and Staphylococcus aureus.
Broad-spectrum antimicrobial:
Nano magnesium oxide has a broad-spectrum antimicrobial effect against a wide range of bacteria and fungi, which means that it can be used in different types of infection control and disinfection settings, including but not limited to medical devices, food packaging, textiles and air purification.
Safe & Environmentally Friendly:
Compared with traditional antimicrobial agents containing heavy metals such as silver and copper, nano-magnesium oxide is non-toxic, non-irritating, produces no harmful residues, is environmentally friendly, and is more suitable for use as an antimicrobial treatment agent for items in long-term contact.
Stability and durability:
Nano magnesium oxide is able to stabilize on the surface during hydration and formation of magnesium hydroxide, maintaining its antimicrobial activity and thus providing continuous antimicrobial protection. In addition, its thermal and chemical stability ensures that effectiveness is maintained over a wide range of environmental conditions.
Composite Applications:
By compositing with other antimicrobial materials, such as loading with silver ions or incorporating specific antimicrobial polymers, the antimicrobial effect of magnesium oxide nanoparticles can be further enhanced, broadening their range of applications.
Easy sterilization conditions:
The sterilization conditions of nano-magnesium oxide are relatively simple and do not require external energy such as UV irradiation, which makes it more convenient for daily use and industrial applications.
In summary, as a new type of inorganic antimicrobial material, nano-magnesium oxide, with its high efficiency, safety and environmentally friendly characteristics, shows a broad application prospect in many industries, especially in the fight against drug-resistant bacteria and the search for safer antimicrobial solutions.
