Answer:
Three benefits of nanotechnology are:
- Nano-technology has no enabled the production of enzymes which can convert cellulose of wood into ethanol which can be used as a fuel.
- High-power rechargeable battery systems can be used for automotive systems due to nano technology.
- Nano particles are now being used for speeding up reactions in a which saves money and reduces pollutants.
Three harmful effects of the nanotechnology are:
- The inhaled nano particles might cause lung inflammation.
- Nano-particles can be inhaled and can travel to different parts of the body causing unknown disorders.
- They can be toxic for the cardiovascular system
No doubt, the benefits of the nanotechnology are enormous. But while developing such techniques and products, special care should be taken that the nano particles do not affect the humans.
