Why is there graphene on the cotton swab of nucleic acid?

COVID-19's nucleic acid testing usually refers to novel coronavirus's nucleic acid testing, while novel coronavirus's nucleic acid testing cotton swab has graphene, which usually does not cause cancer, so there is no need to worry about the cotton swab used in novel coronavirus's nucleic acid testing will cause cancer. Cotton swabs meet safety standards during processing and are usually non-toxic and harmless.

When doing novel coronavirus nucleic acid test, doctors will take samples from throat, nasal cavity and other parts with cotton swabs for examination to determine whether they are infected with novel coronavirus.

Matters needing attention in nucleic acid preparation

1, continue to adhere to the daily nucleic acid sampling, 7: 00 am-12: 00 am. Please take an active, active, timely and orderly part in nucleic acid detection and mobilize your relatives and friends.

2, due to the failure to carry out nucleic acid testing on time caused by the spread of the epidemic risk, to bear the corresponding legal responsibility.

3. Wear a mask during the whole sampling process, do a good job of personal protection, take the initiative to accept body temperature detection, keep a distance of 1 meter from others, do not talk or gather together, and the sampling personnel take off their masks after disinfection, and do not inhale when opening their mouths.
