Nano-Robotics: A Futuristic Medical Treatment!


Robotics is an interdisciplinary field that integrates computer science and engineering. Robotics involves design, construction, operation, and use of robots. The goal of robotics is to design machines that can help and assist humans. Robotics integrates fields of mechanical engineering, electrical engineering, information engineering, mechatronics, electronics, bioengineering, computer engineering, control engineering, software engineering, among others.


This technology is utilized to create machines that can fill in for people and repeat human activities.


Nanorobotics is an emerging technology field creating machines or robots whose components are at or near the scale of a nanometer, nanorobotics refers to the nanotechnology engineering discipline of designing and building nanorobots, with devices ranging in size from 0.1 to 10 micrometres and constructed of nanoscale or molecular components. This technology aims to work at the molecular level, atom by atom, to create large structures with the fundamentally new molecular organization.


The idea of modern nanotechnology has resulted in the creation of smarter and superior nanotechnology products, which has left its imprint on many engineering and basic science fields. It is a multidisciplinary arena that necessitates specialised level input from a variety of scientific and technological disciplines, including physics, chemistry, genetics, medicine, medicinal sciences, engineering, biotechnology, and other biomedical sciences.


Adriano Cavalcanti is the medical nano robotics inventor for the practical hardware architecture of nanorobots which was integrated as a model based on nano bioelectronics for the application in brain aneurysm, cancer, diabetes, cardiology, and environmental monitoring.


Nanorobots of different shapes and sizes are now capable of delivering medicine to specific organs in the human body through veins. For instance, nanorobots can be programmed to transport molecular payloads and cause on-site tumor blood supply blockages, which can lead to tissue death and shrink the tumor.


Nanorobots are made by using several components such as sensors, actuators, control, power, communication, and by interfacing special cross scales between organic-inorganic systems. Medical Nanorobots are nanodevices used for the purpose of maintaining and protecting the human body against pathogens. They can be used very effectively for drug delivery. Normally, drugs work through the entire body before they reach the disease-affected area. Using nanotechnology, the drug can be targeted to a precise location which would make the drug much more effective and reduce the chances of possible side effects.


Nowadays, nanorobots play a crucial role in the field of treatment of cancer, cerebral Aneurysm, removal of kidney stones, elimination of defected parts in the DNA structure, heart attack, and anemia. It has a bright future as an ultrafine drug delivery device. There are many productive discussion been carried out about the potential use and past-present research scenario of nanorobotics and various new approaches.


Characteristics of Nanorobots:

  • Nanorobots must be between 0.5 and 3 microns in scale, with 1-100 nm parts.

  • Nanorobots larger than the ones described above can obstruct capillary movement.

  • The passive, diamond exterior can protect it from being targeted by the immune system.

  • It can communicate with the doctor by decoding messages to acoustic signals with carrier wave frequencies ranging from 1 to 100 MHz.

Benefits of Nanorobotics:

  • Extremely portable and lightweight;

  • Abundant resources available for production

  • Rapid eradication of disease

  • They self clone themselves to replace worn-out units

  • Cost effective

  • Speed up medical treatment

  • Painless treatment

  • Easily disposable

  • Remain operational for years, decades or centuries

  • The chances of any after-effects or recurrences are completely eliminated.

It is possible that the most critical potential role for nanorobots will be to perform difficult repairs that currently require significant surgery, such as removing plaque from blood vessel walls or renewing calcified heart valves. The body has amazing healing mechanisms, but for causes that are still unexplained, those behaviours prove to be unlikely.
