Successfully manufactured Vietnamese-branded silver nanoparticles.

Dr. Truong Van Chuong and his colleagues at the University of Science, Hue University, have successfully manufactured silver nanoparticles, applying them to production to proactively develop high-tech, low-cost products under a Vietnamese brand.

Mylife-branded products such as antibacterial face masks, nano-silver solution for deodorizing and disinfecting, and feminine hygiene solutions from Viet Delta High-Tech Joint Stock Company have been registered as cosmetic products and are being sold in the Vietnamese market.

According to Dr. Chuong, one of the earliest and most widely used nanoparticles is silver nanoparticles. Research has shown that at the nanoscale, silver exhibits distinct and extremely valuable physical, chemical, and biological properties, with its antibacterial activity increasing by approximately 50,000 times compared to silver ions.

In recent years, with the increase in antibiotic-resistant bacteria and pathogenic fungi for which specific treatments are lacking, research and development of silver-containing products to combat them has become a new and urgent direction.

The research team has developed a novel solution for fabricating silver nanoparticle solutions using a combination of chemical, physical, and biological methods. The team utilized a mixture of extracts from various herbs to enhance both reducing and stabilizing agents.

To accelerate the reduction process, the team used a combination of ultrasound and microwave effects. All of these devices were fabricated by the team, and as a result, they successfully created aqueous silver nanoparticle solutions with different concentrations.

Building on this success, silver nanoparticle solution has been applied to produce antibacterial face masks, antibacterial deodorizing solutions, and feminine hygiene solutions. Using silver nanoparticle filters, the team has also experimented with creating simple filtration devices to help people in flood-affected areas produce clean drinking water.

Furthermore, nanosilver can be used as a source material to manufacture many other products such as antibacterial paints, new generation pesticides, supplements to prevent diseases in livestock, aquaculture, tissue culture, etc.

Nanoparticles of silver, combined with extracts from various domestic herbs, can be used to create new, environmentally friendly antibacterial and antifungal products.
