Nano robots applied to medicine


Nanorobotics is the field of emerging technologies that creates machines or robots whose components are at or close to the nanometer scale (10−9 meters)1. More specifically, nanorobotics refers to the nanotechnological engineering of the design and construction of nanorobots, these devices having a size of about 0.1 to 10 micrometers and built with nanoscale or molecular components. The names of nanobots, nanoids, nanites, nanomachines or nanomites have also been used to describe these devices that are currently in the research and development phase.

Nanometric-scale technology emerged 50 years ago, creating a new dimension called to revolutionize the world we know, as it allows the molecular structure of materials to be manipulated to change their intrinsic properties and obtain others with revolutionary applications. This discipline, which flourished between the 1960s and 1980s, opens up an immense universe of possibilities for contemporary science and industry and presents a booming global market whose value will exceed 125,000 million dollars in the next five years, according to the Global Nanotechnology Market report .

What is nano robotics?

Documenting myself in, I was impressed by the applications of these machines on a microscopic scale.

Main applications for nano and micro machines

The applications for these devices seem endless and these are, from my point of view, the most interesting:

  • Cancer treatment : they will allow the identification and destruction of cancer cells in a much more effective and accurate way.
  • Mechanisms for the targeted administration of drugs  for the control and prevention of diseases.
  • Image diagnosis:  creation of nanoparticles that gather in certain tissues so that when scanning the body with magnetic resonance systems, problems such as diabetes can be detected.
  • New sensing devices : With almost unlimited customization properties for sensing functions, nanorobotics is going to provide us with incredible sensing capabilities that we can integrate into our systems to monitor and measure everything around us.
  • Information Storage Devices : A bioengineer and geneticist at Harvard’s Wyss Institute has managed to store 5.5 petabits of data (about 700 terabytes) in a single gram of DNA, surpassing by 1,000 times the previous record for data density storable in DNA.
  • New energy systems:  Nanorobotics could play an important role in developing more efficient renewable energy systems or making our current machines more energy efficient, requiring less energy to run at the same level or with the same energy function at a higher level.
  • Meta super strong materials:  A team at Caltech has developed a new material, made on a nano scale, with interlocking struts. As if it were an Eiffel tower, it is one of the strongest and lightest substances ever created.
  • Smart windows and walls:  electrochromic devices that, depending on the potential applied, change color. They are intended to be used for energy efficient smart windows to control the internal temperature of a room, clean themselves and other applications.
  • icrosponges to clean oceans:  a sponge, made of carbon nanotubes, capable of absorbing contaminants (fertilizers, pesticides, pharmaceuticals…) from the water. This project is three times more efficient than other previous initiatives and its study has been published in the journal Nanotechnology, from IOP Publishing.
  • Replicators or “molecular assemblers ”: devices capable of directing chemical reactions, managing to place reactive molecules with atomic precision.
  • Health sensors : they would monitor blood chemistry, notifying parameters out of control, detecting spoiled food, inflammation in the body and much more.

I was even more impressed when talking about the fight against cancer that this technology can achieve and other applications in medicine.
