Nano Silver Dislike Bacteria. See Why
a test report
The following lab test report will show you exactly why Nano Silver dislike bacteria as much as we human does.
Overview of Test Environment
Date Tested : April 15, 2009Testing material : PVC Coil matTesting category: Antibacterial test & Antifungal test
- ASTM G-21 (antifungal test)
Our First Test
What is ASTM G-21?
ASTM G 21 is a Standard Practice for Determining Resistance of Synthetic Polymeric Materials to Fungi.

- ASTM G-21 (antifungal test)
Our First Test
Conditions
The culture ground: NSGA MediumThe cultivating period: 2weeksThe condition of cultivation : 27℃ Humidity incubator
Test material 1 Test material 2 DAUFON AG+
Test material 3 Test material 4
As you can see from Test Material 2, DAUFON AG+ forms a protective field surrounding it. Therefore, this will stop the attack of fungal to DAUFON AG+. While the other 3 test materials, attracts more fungal and is a good place for fungal to grows.
- JIS L 1902 (antifungal test)
Our Second Test
What is JIS L 1902?
JIS L 1902 is testing for antibacterial activity and efficacy on textile products
Index: Resistance to fungi on the testing sample

Our Second Test (A)
As you can see from Test Material 2, DAUFON AG+ dispel bacterial and forms a “halo” beside it. This clearly shows that not only DAUFON AG+ is antifungal as shown in the previous test, it is also a powerful antibacterial agent.
Conditions
The culture ground: Nutrient Agar MediumThe period of cultivation: 1 DayRelevant mycelium: Escherichia coli
Test material 1 (Escherichia coli) Test material 3 (Escherichia coli)Test material 2 (Escherichia coli) DAUFON AG+
Test material 4 (Escherichia coli)
- JIS 1902 (antibacterial test)
Our Second Test (B)
As you can see from Test Material 2, DAUFON AG+ dispel bacterial and forms a “halo” beside it. This clearly shows that not only DAUFON AG+ is antifungal as shown in the previous test, it is also a powerful antibacterial agent.
Conditions
The culture ground: Nutrient Agar MediumThe period of cultivation: 1 DayRelevant mycelium: Stapylococcus aureus
Test material 1 (Stapylococcus aureus)
Test material 4 (Stapylococcus aureus)
Test material 3 (Stapylococcus aureus)
Test material 2 (Stapylococcus aureus) DAUFON AG+
Now that you have seen how powerful Silver Nano Technology is, imagine this….
…. Combine Nano Silver Technology and the practical use of carpet, you have the ultimate solution to keep
your house clean and free of bacterial.
