What's on the nucleic acid swab?

At present, the main component of cotton swabs used for nucleic acid detection is absorbent cotton, and the top is flocking cotton swabs. These two substances are non-toxic and will not cause cancer. Flocking cotton swab adopts nylon fiber flocking technology, and the front end is covered with vertically fixed nylon short fiber, so that the whole collection area of cotton swab has no adsorption holes, so that the collected samples will not be dispersed in the fibers, which is beneficial to eluting the samples faster and more efficiently.
