What are the Nanobots? | What are Nanobots used for?

NANOBOTS

What are the Nanobots?

Nanobots are nanoscopic robots or what is the same as a robot about the size of an atom. Nanotechnology studies matter from a nanometric resolution level. 1 nanometer (unit of length) corresponds to one billionth of a meter. We must know that an atom is less than 1 nanometer, so we say that the size of a nanobot should be similar to that of an atom. Nano means smaller than micro.



The study of nanobots is within the science of nanorobotics or nanotechnology and can also be called nanobots, nanoides, nanites, nanoagents, nanorobots or nanomachines.

Future or Reality. The Nanobots Problem

 If we talk about the future, imagine that you go to the doctor for treatment for a persistent fever. Instead of giving you a pill or an injection, the doctor sends you to a special medical team that implants a small robot into your bloodstream. The robot detects the cause of the fever, travels to the appropriate system and provides a dose of the medication directly to the infected area. Future or reality? For the future.

 The biggest problem right now is to provide the nanobots with autonomous movement and a navigation system.

 Some designs using the patient's own body as a way to generate energy for the nanobots using blood flow or heat from the human body.

 As for the movement, it is being investigated to provide cilia (limbs in the form of hairs) that vibrate. Most researchers look at microorganisms (such as bacteria) to try to give nanobots movement. There are even some who use a simple propeller.

 To guide the nanobots, magnetic fields external to the human body are being used.




What are Nanobots used for?

  They can be used to travel inside the human body to fight some diseases or repair organs, but they can also perform other functions, such as cleaning the environment, detecting pests or cleaning up an oil spill.

  Although it is a field in which there is a long way to go, the use of nanobots for the cure of diseases, and in particular cancer, is one of the most hopeful fields for the medicine of the future.

  Researchers from the Israel Institute of Technology (Technion) and the Federal Polytechnic School of Zurich, would have created nanobots made of polymers and magnetic nanowires, capable of being introduced into the human bloodstream and remote control inside to detect cancer cells and release drugs on they.

All this is still undergoing experimentation and has not yet been tested in humans, perhaps there are still a few years until we can make real use of nanobots in medicine, although in recent years there has been tremendous progress in many of the necessary fields To create this technology.

  Another of the uses of nanobots is for water treatment or cleaning of the environment. One could send hundreds, thousands, millions of these devices and have them swim through the water to see if it is contaminated, catalyze contaminants, and then collect them.

Types of NanoBots

  The two basic types of nanobots are assemblers and self-replicators or self-replicators.

  - Assemblers are nanobots in the form of simple cells that may be able to decipher molecules or atoms of different types, and controlled by specific programs. By their use they are also called molecular assemblers, as a reference to a structure that exists inside each cell of every living being called ribosome that are the natural "assemblers."

  - Self-replicants are essentially nanobots capable of duplicating (self-replicating) themselves at high speed. This type of duplication helps build large-scale applications or deploy nanobots for large-scale tasks.

In military investigation the self-replicators can be used as an armor of the military body and that is capable of self-repair in case of damage.

  These nanorobots can also be a threat according to scientists. The "gray plague" is a threat from an army of self-replicating nanorobots out of control destroying the planet.

History of the Nanobots

  Already in 1959 the theoretical physicist Richard Feynman (winner of the Nobel Prize in Physics in 1965) predicted that one day it would be possible to build machines so tiny that they would be formed of only a few thousand atoms.

  Later in the 1987 novel, "Engines of Creation," Eric Drexler describes nanobots capable of destroying cancer cells, collecting free radicals, or repairing damage to cell tissues.

  From here the nanorobots began to be studied and investigated and at the moment promises to be the next step in the evolution of human technique. A revolution that simply will not go unnoticed in the coming years, but that is not yet final.

  Genetics, biochemistry, physics, engineering and materials are the pillars for the creation and development of nanotechnology.
