Nanotechnology: A Boon or a Curse

The term “nanotechnology” is widely used to refer to both technologies of emerging field as well as science. Controlled manipulation of atomic properties is employed by Nanotechnology, so as to make materials as well as other functional systems having selective capabilities. Although Nanotechnology and Nanoscience may sound all the same, yet there is a major difference between the two. Nanoscience involves the study of nanostructures, while Nanotechnology deals with the implementation and application of the understandings in several industries worldwide.

The term Nanotechnology was coined in the year 1974 by Professor Norio Taniguchi. He wrote a paper wherein he described the process of combination or separation of atoms and molecules. Yet the term gained popularity with the help of Dr. K Eric Drexler through his book named “The Engines of Creation”, his first book published in 1986, of this subject.

Nanotechnology is considered to be a major trend and a technology disruptive. It endeavors to increase industrial efficiency as well as develop traditional and comprehensive new applications through technologies that are newly emerging. Nano researchers normally deal with two main forms of Nanotechnology- Top down and Bottom up nanotechnologies. Top down approach deals with the miniaturization of structures while the Bottom up approach focuses on enlargement of several structures.

Nanotechnology plays a significant role in a wide range of industries, like electronics, pharmaceuticals, optoelectronic, biomedical, cosmetics, household appliances, plastics, security, defense, communications, automotive and aerospace industries, among others. Nanotechnology can also cause us potential harm, as it can be utilized to create various machines for causing destruction. This technology can be employed to invent weapons that will have endless possibilities in causing havoc and irrevocable destruction. This is known as nanotech weaponry. A few of the possible situations are listed below:

  • Nano-poison: A nanobot, designed to cause harm to the host, can be dropped in someone’s food. Only one hundred nanograms of Botulism are enough to kill a human being. The nanobot wait until it reaches the brain and then deploy its payload.
  • Nano-reconnaissance: A small nanobot can be deployed for the infiltration of computers and supervise frequencies that are picked up in the RAM. Information can also be stolen from the computer’s hard drive.
  • Nano-brainwashers: Nanobots can be employed for “brainwashing” or destroying your memory. If an attacker deploys a nanobot onto his enemy, then he can easily program his victim, while speaking on various subjects.
  •  Nano-infertility: Nanobots can be used to make a person infertile.

Nano-duplication: Nanobots can be used to duplicate DNA, eggs, sperms; also an entire human being in more complicated projects.
