INTRODUCTION In recent years, nanotechnology has unveiled a sequence of unbelievable technological opportunities that have brought about the existence of novel technological and scientific fields, with the potential of influencing change within a significant number of citizens. Some opportunities are already tapped by researchers in other fields of study related to bio-robotics, while others remain unexploited. This paper provides an assessment of the application of nanotechnology and its impacts on the development of innovative solutions for sensing and actuation, as well as the success of Nano- robots, micro-robots, and robotic systems at large. Besides, the paper openly describes the challenges and the utmost relevant research avenues that are associated with Nanotechnology. [13] II. NANOTECHNOLOGY FOR ACTAUTION In any machine, actuation is a primary function as it allows its movement and interaction with the environment. Artificial molecular machines provide an ideal approach to nano-actuation. The progress of these blocks is primarily based on the chemical approaches for manipulating and synthesizing the structures [4]. Supra-molecular or single molecules systems are attained and controlled by distant stimuli like the light. However, they portray certain limitations highlighted by [5]. Kassies highlights them as follows: i. The existence of such machines is only in solution, hence hardly addresses solely. ii. Continuous rotations in the absence of mechanical connection with weight are unnecessary. iii. The outcome of the process is extremely minimum. A report recently published not only defined roadmap but also highlighted that structured sets of molecular machines, combined with metal-organic bases, are applied as nano-robotic arms. [4] A. Bio-motors for actuation Bio-motors are also nanoscales that often within the series of sets of nanometers. Starting with the initial trails of ascribing an F1-ATPase molecule to a surface to generate measurable power and application of kinesin (motor protein), noticeable steps were attained in this sector [7]. Rudimentary DNA strollers can run across the self-joint tracks, including the DNA motors that independently rotate, getting charged through catalyzing the RNA or DNA fuel reactions [8]. Recently, the origami DNA acquiescent assembly has also been developed, illustrating their use as actuation means [9]. Motors that are DNA based portray several issues: they are soft material based hence limited durability, operating under narrow range pH and temperature conditions, and are difficult to control. B. Magnetic actuators: Nano-scale devices actuation is possible through remote forces. For instance, magnetic fields are magnetic particles applicable and magnetized living elements. An example is under MRI (Magnetic Resonance Imaging) control [7]. The magnetic material’s characteristics are vital in the control of their movement. The primary character is magnetic susceptibility (x), referred to as the magnetization induced ratio; (M) to (H), directed to the magnetic field. Fe3O4 (Iron Oxide) has a high (x) as a nanoparticle as well as its y-Fe2O3 (Maghemite). The size of these elements is 15-80 nm [4], hence allows the magnetic actuation of considerably small structures. Micro-robotics are devices that integrate both living elements and artificial components intending to exploit the specific structures of a living organism within an interconnected system. Another approach in research is centered on the use of insect or mammalian whole cell muscles to power micro- devices [8]. Regarding NEMS (Nano Electro-Mechanical Systems) for actuation, the majority are resonant devices; with the nano-mechanical, structure is excited in its resonant mode [6]. They are often more adoptable medical constraints than traditional motors, which require bulky and distal mechanisms, depending on direct driven or tendon drive actuation approaches, respectively. Differently from shape memory alloys and thermal actuators fluidic solution operate at ambient or body temperature. 2020 5th IEEE International Conference on Recent Advances and Innovations in Engineering (ICRAIE) | 978-1-7281-8867-6/20/$31.00 ©2020 IEEE | DOI: 10.1109/ICRAIE51050.2020.9358314 Authorized licensed use limited to: Lakehead University.
