1, nanotechnology is around us, and slowly, we will put on nano clothes. Cancer patients can effectively prevent cancer by wearing nano clothes. Ordinary people wearing nano clothes can also prevent COVID-19 from being infected, so that we are no longer afraid of COVID-19.

I will apply nanotechnology to my research. The schoolbag made of nano-materials can not only be folded and carried conveniently, but also has the function of zooming. When not in use, it can be shrunk together with stationery, only the size of an eraser, and we can put it in our pockets; When used, it will automatically change back to its original appearance, making the bag neat. Nano can also protect books like new books.

If nanotechnology is applied to the security door, it will be of great use. If a thief touches the door, the nano-robot will automatically identify it and send the information to the owner and the police, so that the thief can't fly. In addition, the door 263 is automatically locked and the alarm is pulled. When the alarm is released, the lock will be released.

4. Nanotechnology is applied to clothes to prevent cold in winter and heatstroke in summer. Finally, you don't have to dress like a penguin in winter and sweat in summer. When nanotechnology is applied to food, the food will be safe and nutritious, without pesticide residues and additives, and adults and children can safely eat it.

The pen made of nanometer can supervise our writing posture, remind us when we make mistakes in our homework, and can be used for several years without changing ink bags.

6. Nano cosmetics are coming soon. They are antioxidants, anti-aging and can make us white. And nano armor. If the bullet comes, it will not only be ok, but also bounce back and hit our enemy again.
