Even though creating tiny robots to treat illnesses may seem like something out of sci-fi novels set in the distant future where humans are enhanced by machines, early research into this topic is already well under way. There are no such things as nanobots or nanomites like in the science fiction novel Prey by Michael Crichton. A nanorobot, or nanobot, is a common term for molecules with a special property that allows them to be programmed to perform a specific task. It should not be confused with these fictitious nanorobots. These nanobots are real, and research and development on them are ongoing. Targeted drug delivery with micro- and nanorobots aims to get to the body's most difficult-to-reach areas. It's still difficult to create medications that can pass the blood-brain barrier, for instance. The remote-controlled microrobots used by startups like Bionaut Labs to treat neurological diseases, however, have garnered media attention. Microrobots are, as their name implies, larger than nanorobots and are measured on the micrometre scale as opposed to nanorobots on the nanometre scale. One millionth of a metre is equal to one micrometre in size. Robotics is the study and application of robots, which are fully autonomous electronic, electrical, or mechanical devices used in tasks like manufacturing. When you scale down a robot to a few billionths of a metre, you are talking about nanotechnology robotics, or simply, nanorobotics. The study of nanorobotics combines a number of fields, including physical modelling at the nanoscale and nanofabrication techniques used to create nanomotors, nanoactuators, and nanosensors.Nanorobotics also includes the kinds of robots used for these tasks as well as nanorobotic manipulation technologies, such as the assembly of nanometer-sized parts or the manipulation of biological cells or molecules. The definitions of these robots are still ambiguous outside of scale. According to Yuebing Zheng, PhD, an associate professor at the University of Texas at Austin, autonomous sensory behaviour is incorporated into the designs for macroscopic robots. However, because they are too small to fit inside of micro and nanorobots, sensory or control systems are frequently found outside of these machines, he continues. This implies that these machines are frequently operated from the outside, which presents difficulties for research, according to Zheng. Scaling up for clinical studies is therefore challenging, according to Sylvain MarTel, PhD, director of the nanorobotics laboratory at Polytechnique Montréal. A Wide Range of Strategies Insights into the fundamentals of the technology are combined with the development of novel applications in the rapidly expanding field of micro- and nanorobotic research, according to Steager. According to Mariana Medina-Sánchez, PhD, group head at the Institute for Integrative Nanosciences-IFW Dresden, Germany, researchers previously concentrated on foundational research as is the case with every new field. She claims that currently, scientists are concentrating on the application of these ideas to preclinical animal models and medicinal fields. According to Medina-Sánchez, this means that the field is currently researching the best materials and designs for gadgets, with a focus on enhancing their control. In contrast to what you might have read or seen in fiction, nanobots don't exist yet and probably won't for some time. The difficulty of simultaneously controlling many molecule-sized machines to carry out a desired task is one of the fundamental issues to be solved for potential future molecular machinery. Over the past few years, simple nanoscale motors have been realized, but these are only systems that generate physical motion of their component parts at a nanoscale level. Many revolutionary developments must be made in order to create a true nanorobot, a fully autonomous electronic, electric, or mechanical device that can perform tasks like manufacturing at the nanoscale. One of them is how to design and programme the 'brains' of these machines in order to control a large number of devices. Another challenge is to distinguish between the idea of science fiction-style "thinking" robots (artificial intelligence) and a more practical (yet still far-off) idea of machines that can be programmed to carry out a specific task in a more or less autonomous manner for a period of time. Nanobots could be used in medicine to deliver drugs to specific tissues, eradicate cancer cells, and enhance vaccines. As DNA probes, cell imaging tools, and cell-specific delivery systems, nanobots are also utilised in research.
