PVC‑SiO2‑Ag composite as a powerful biocide and anti‑SARS‑CoV‑2 material

The ongoing COVID-19 pandemic has pushed scientists and technologists to find novel strategies to develop new materials to prevent the transmission, spread, and entry of pathogens into the human body. In this report, the fabrication of polyvinyl chloride (PVC)-SiO2-Ag composite is presented, in which the percentage of Ag is 0.84% wt. Our findings render that this composite eliminates (> 99.8%) bacteria and fungus (Staphylococcus aureus, Escherichia coli, Penicillium funiculosum) and SARS-CoV-2, by surface contact in 2 h hours and 15 min, respectively. Specific migration analysis shown that the use of the PVC-SiO2-Ag composite is considered safe and effective for food preservation. This research and innovation front can be considered a breakthrough for the design of biocide materials. Future directions for this exciting and highly significant research field can open the door to the development of new technologies for the fabrication of packaging films to protect consumer products (such as fruits, vegetables, and other foods).

Packaging additive increases the shelf life of fresh milk by 100%! Ask me how?

It estimates that food loss and waste costs the global economy $936 billion a year and Nanox is helping to solve this problem using antimicrobial technology to apply mainly in food packaging. Nanox creates a technology platform that can decrease the food waste improving the food shelf-life. Depending on the food, Nanox's products can double the shelf life. NANOX develops, produces and commercializes silver based inorganic antimicrobials (safer and more efficient), which can be incorporated into a wide range of materials, making them free bacteria and fungi. The product needs to be added in the manufacturing process of the products, in other words, in the food packaging case it is necessary to add during the manufacturing process of the packaging. The main benefit for food packaging is to improve the food shelf life and decrease the food waste. We have a case in the fresh milk market where our product extended the fresh milk shelf life from 8 to 16 days. Nanox products have registered in FDA and EPA and available in masterbatch form.

Ag nanoparticles-based antimicrobial polycotton fabrics to prevent the transmission and spread of SARS-CoV-2

Pathogens (bacteria, fungus and virus) are becoming a potential threat to the health of human beings and environment worldwide. They widely exist in the environment, with characteristics of variety, spreading quickly and easily causing adverse reactions. In this work, an Ag-based material is used to be incorporated and functionalized in polycotton fabrics using pad-dry-cure method. This composite proved to be effective for inhibiting the SARS-CoV-2 virus, decreasing the number of replicates in 99.99% after an incubation period of 2 minutes. In addition, it caused 99.99% inhibition of the pathogens S. aureus, E. coli and C. albicans, preventing cross-infections and does not cause allergies or photoirritation processes, demonstrating the safety of its use.
