CONCLUSION :As per our aim we have proposed the usage in heart surgery due to this number of risks and side effects behind is reduced. The same technique is used in various treatments like cancer, breaking kidney stones, breaking liver stones, parasite removal only with slight modification. With in ten year several advancement technologies should be made by researchers from this nanorobotics.
