Nanobots in Medical Field: A Critical Overview

Abstract

Today, the health care industry is focusing on developing minimum invasive techniques for diagnosis, as well as for the treatment of ailments.Advancement in technology is more essential for the treatment of many problems such as implant of bones and membranes.One such technique flourishes robots using nanotechnology which are known as nanobots.Nano robotics is an emerging technology creating machines or robots whose components are at or near the scale of a nanometre ( meters).Nanobots will help to build a platform between the technological gaps of physics, chemistry and biology on the nano-scale.These nanobots can address the path to many creative approaches and will result in new methods and products for both technological and medical-pharmaceutical applications.Furthermore, nanobots are good applicants for complex treatments with their size being very small.Nanobots are used as drug delivery systems and contrast agents.It is contended that coated nanobots are functionalized with targeted molecules are interacting with external devices and offering real potentials for medical applications.This paper directs how a nanobot work and how it contribute to medical robotization with their advantages and disadvantages.
