Antiviral material testing

Antiviral material testing

experimental background

The outbreak and epidemic of novel coronavirus has caused serious harm to human health, which has become a public problem in the field of global medicine and health. The use of antiviral materials as a powerful measure to effectively inhibit and extinguish a virus to protect human health has received extensive attention. However, whether materials with high antiviral function can effectively kill and eliminate viruses requires antiviral material testing to get the answer.

test subject

Antiviral material testing objects include textiles and leather, ceramic bathroom, polymer materials, antibacterial glass, paint film, filter, nanomaterials and other materials.

test standard

ISO 21702-2019 Determination of antiviral activity of plastics and other non-porous surfaces
ISO 18184-2019 Textiles - Determination of antiviral activity, etc

trial service

You can provide your own test plan or entrust our company to formulate a test plan for antiviral materials according to the characteristics of the tested products

test flow

1. Hang a drop of 0.1 ml of influenza virus on the sample, cover it with a plastic film, and maintain humidity.
2. Treatment group: incubated at 25 ° C for 2 hours, added 0.9 m1 maintenance medium to rinse samples and plastic films, and inoculated with 96-well plates to detect TCID50 °.
3, control group: Immediately add 0.9m1 maintenance medium rinsing, inoculation 96 well plate detected TCID50 °.
4. Virus killing rate (%) = TCID50 control - TCID50 control)/tcid5o control × 100%.
