A Brief Review on Nanorobots

Abstract

This paper proposes the overview of the nanobots. Nanorobots is the emerging technology field of developing machines which are of nanoscale. The major applications of nanorobots are in medical field. They are used in medical field for treating cancer, checking blood contents, diagnoses and accurate drug delivery. Overview of latest developments in nanomachines or nanobots are also given in this paper.

A Brief Review on Challenges in Design and Development of Nanorobots for Medical Applications

“…Nanotechnology involves the process of designing, fabricating, and manipulating materials at the nanoscale [1]. The study of robots at the nanoscale is defined as nanorobotics, and incorporated technology is known as nanotechnology.…”

“…Nanobots (A.K.A. nanorobots), which are currently the focus of an emerging field of research, are also referred to as nanites, nanoids, nanomachines, or nano-mites [1,4]; however, in general, nanobot consists of two words-'nano' and 'bot'. 'Nano' refers to very small or minute, and 'bot' refers to a device that can be controlled by a program, i.e.…”

“…'Nano' refers to very small or minute, and 'bot' refers to a device that can be controlled by a program, i.e. a short term for a robot [1]. Nanorobots have several potential applications in the medical field including cancer treatment [5,6], surgery, precision medicine [7], diabetes monitoring, dentistry, blood monitoring and drug delivery [1,4,5].…”

“…a short term for a robot [1]. Nanorobots have several potential applications in the medical field including cancer treatment [5,6], surgery, precision medicine [7], diabetes monitoring, dentistry, blood monitoring and drug delivery [1,4,5]. Currently, mobile phones are proving to be a useful feedback device in accomplishing data transmission for communication, control, and energy supply inside the body.…”

“…In addition, the emergence of new materials and their application in fabricating sensors and actuators has resulted in devices in the nanoscale range [6][7][8][9]. Due to the potential for nanorobots to work individually or in swarms in a wide variety of applications, ranging from medicine, environmental surveillance and monitoring, armed forces, and many more emerging applications, it is essential to conduct a review on the existing state-of-the-art nanorobotic systems [1,10,11].…”
