Write down any four situations in which nanotechnology can be made use of.

The four situation where we should use nanotechnology to improve the current situation:-

•Situation 1: In a critical operation of human-like cancer or removing tumor nano-drones can be used to do the operation without any actual surgery. Thus, increases the chance of saving human life.

•Situation 2: When a traveler going through any life-threatening situation, a nano-device which helps in the lightning fire as well as self-protection from wild animals can be useful.

•Situation 3: Suppose, you need urgently energy or any source of electricity, and you are in the middle of nowhere for that situation we could build up smaller devices which are easy to carry and helps to provide electricity in times of need.

•Situation 4: When an astronaut is exploring in space he/she can use nanotechnology, it will surely reduce the mass and make exploration easy. For example, the suit he is wearing can be made from nano particles for extreme condition survival.
