Do You know about nanoscience and nanotechnology ?

Written by Pradeep Kumar

Introduction

It is indisputable that modern society is not surprised by the creations that have been made in the world, and are accepted as part of daily life, however there remains the question of how they do it, its effects on health, the true objectives so that they are realized, but what is coming will really surprise, and this will be in the not too distant future, since they will be things that change our lives for their applications, advantages and disadvantages of having created it.

However, there have always been comments, more or less informed, about the new technology of the 21st century, although the massive introduction into our world, technology has already changed the way we see the world and where we really are going.

Then the new technological revolution will not surprise for its gigantic size as it was in the last century, but for its surprisingly small size called nanotechnology, where it is associated, on the one hand, with “molecular manufacturing” whose viability would have an enormous impact in our lives. Among the effects, its potential impacts on medicine, biology, the environment, computer science, electronics, construction stand out. At present, the main practical advances are already given in some fields: in physics nanoparticles, electronics and nanotube construction. The most questioned progress in the matter of nanorobots and self-reproduction are the subject of controversy among experts. There is no doubt that the revolution has begun. And also the debate about its benefits and risks.

And along the same lines, the objective of this publication is intended to be a scientific contribution and analyze the progress made and analysis of experts in this field in order to contribute to development information.

OBJECTIVES

Facilitate access to information for citizens and stakeholders on a topic of fundamental importance to our societies.

Provide useful information to readers to understand new technological advances and developments to understand an increasingly near future.

Encourage debate about the advantages and risks associated with nanoscience and nanotechnology.

Summary

This article describes the analysis and advances of nanotechnology and nanoscience in different fields, but essentially these are issues of the introduction of nanotechnology in electronics, alternative energies, what effects these introductions have, in today’s world and Its next objectives to be met and what are the advantages and disadvantages we must take into account that they will come in the near future.

Truly, there is information regarding increases in the likelihood of solutions to confront indigenous cancer cells, and the benefits of the applicability of nanotechnology in the environmental field, but it has really been possible to establish a cause-effect relationship of these issues.

Among this analysis, we have the point of view of two people and their approach to health, where it is the first real solution based on cell therapy, where they provide us with two approaches.

Nanoscience

Nanoscience has been linked since the 80s with contributions from Eric Drexler and with his contributions on “molecular nanotechnology”, where this is, the construction of nanomachines made of atoms and which these are capable of building other molecular components. Since then Drexler is considered one of the greatest visionaries on the subject of nanotechnology. In 1986, in the book “Engines of Creation” he introduced the promises and dangers of molecular manipulation.

Another of the greats in nanoscience is Richard Feynman and is considered the father of “nanoscience” and won the Nobel Prize in Physics, in 1959 he proposed to manufacture products based on a rearrangement of atoms and molecules. In the same year, the great physicist wrote an article that analyzed how computers could consume very little energy and achieve amazing speeds and all this would be obtained by working with individual atoms.

So this made Charles Vest (former president of MIT) announce that nanotechnology will lead us to a second industrial revolution in the 21st century, at that time he said that would mean numerous advances for many industries and new materials with extraordinary properties, new applications. with incredibly faster components, molecular sensors capable of detecting and destroying cancer cells in the most delicate parts of the human body and many more applications and that among many advances in nanoscience will be the great technological advances that will change the world.

Nanotechnology

Let’s start by clarifying the meaning of the prefix “nano”, it is a Greek prefix that indicates a measure (10-9 = 0.000 000 001) and is not an object.

Then, nanotechnology is the study, design, creation, manipulation, and application of materials, devices, and functional systems through the control of matter on a nanoscale, and the exploitation of phenomena and properties of matter on a nanoscale. When the matter is manipulated on such a tiny scale of atoms and molecules, it demonstrates completely new phenomena and properties. Therefore, scientists use nanotechnology to create new and inexpensive materials, devices and systems with unique properties.

Advantages and disadvantages

Advantage:

  • Molecular nanotechnology could manufacture cheap and sophisticated equipment for medical research and health, as well as reduce diseases that affect humans.
  • With the implementation of nanotechnology, computer equipment would be extremely cheap and transportable.
  • The efficient and cheap construction of light and strong structures, electrical equipment and energy storage devices would allow the use of solar thermal energy as the main source.
  • The innovation of new technological products would allow the world’s society to live with minimal environmental impact.
  • Electronic components could be made with lower energy consumption, favoring the environment.

Disadvantages:

  • The power of nanotechnology could be the cause of a new arms race between two competing countries.
  • The inexpensive production and the duplicity of designs could lead to major changes in the economy.
  • The exploitation of cheap products could cause significant damage to the environment.
  • Within the black market, it would be to traffic smaller weapons that would be very destructive.

Conclusions

Nanotechnology is the science of the future, where it allows us to manipulate matter by giving it different applications, and such manipulations are expected to allow us to obtain great results in different fields.

Nanotechnology is expected to be the solution to many problems and to be a great benefit in society, as long as it is well viable, for purposes that benefit society.

In electronics, the use of nanoparticles will allow these elements to be increasingly smaller and their costs are not so high.

The use of nanoparticles to produce alternative energies will be the best advance that can be produced since it will help us to significantly reduce pollution.
