Short notes on NANOROBOTICS


NANOROBOTICS is the latest technology that is used for developing minute robots below the range of 10-9 meters. It is one of the important categories of nanotechnology. It is also referred as NANITES, NANOBOTS, NANOMITES, and NANOIDS. After micro – machines, nanorobotics is considered as the next level of miniaturization.

Nanorobots in medical applications:

The nanorobots are mainly developed for performing medical tasks. It is sent into a human body for identifying problems, injecting drugs, and to do more. It can be differentiated into two different kinds by the way nanorobots are used. The first type of nanorobots will be implemented for surgery intervention and another one for examining patient bodies. It uses wireless, highly sensitive, very fast sensors for detection purposes.

The nanorobots are capable of finding and breaking the stones in the kidneys. It can check and repair the DNA structures, and they are able to decrease the genetic diseases of a person as well. For long years, heart attacks have killed many lives due to coronary arteries blockage. To get rid out of it, the nanorobots are used to clear the block. It can also cure the problems in spinal cord regions.

In future, nanorobots will be designed to find the lack of glucose for preventing diabetes. It will be able to detect stenosed blood vessels. Most importantly, Cancer is expected to be cured by injecting anti – HIV drugs.

Nanorobots in Environment:

At present, pollution has been increased due to vehicles, industrial wastes, dust, and so on. As a result, diseases will also be maximized. For reducing this problem, nanorobots are applied to purify the CO2 (Carbon dioxide) and O2 (Oxygen). Another big setback is water pollution and therefore, the nanorobots are put into the act for purifying the sewer wastes and reservoirs. By this process, the need for medication will be decreased and healthy atmosphere will be created.


  • Cost of surgery is low,
  • No operation failures, and
  • Less risk.


  • Complicated maintenance,
  • Very costly for installation purposes, and
  • Bunch of various nanorobots forming each other will cause harm.

Overall, the use of nanorobots in both environment and medical applications will definitely save plenty of patient lives.
