Nano freezer, nano insole, nano washing machine, nano cutter, nano CD, etc.

(1) Nano-materials are adopted, so that the refrigerator can resist bacteria: the nano-coating has the function of sterilization and deodorization, so that food and vegetables can be kept fresh for a long time.

② Take the "carbon nanotube ladder" to travel in space.

(3) Stealth fighters use nano-absorbing materials to absorb and detect radar waves, so that the radar cannot see them at all.
