The future of nanorobots

Nanorobots seems to be some sort of fantastic creatures described on the pages of science fiction books, however they are the current "trend" in the labs around the world, working on nanotechnologies.

First of all, "Nano" means one billionth (0.000000001 or 10-9). The nano-technologies are bases on "nano" objects with the size of 1 to 100 nanometers. Actually, this is the size of unique atoms and molecules, and nano-technologies operate with the material on that level.

Humans tend to copy the nature in the inventions, and nanorobots have prototypes in the real life as well. Indeed, natural nanorobots, such as "ribosomes", commonly called "molecular machines", could be found in our living cells. Molecular machines in size of builds our body in the process of biological protein synthesis, a miracle that stands behind the process of natural growth.

The difference between natural molecular machines and nanorobots is that latter could be controlled and programmed to build something according to the order. Working on the atomic level, nanorobots could disintegrate any source material (waste, water, oil) and build a complete new structure atom by atom. Nanorobots could even build other nanorobots that could lead us to unbelievable possibilities.

Just imagine that nanorobots could manipulate atoms and build new structures the same way as child could build constructions with LEGO. Even though some people believe that such application of nanorobots is just a futuristic fantasy, you should remember that your body is alive thanks to the trillions of living natural nanorobots in our cells that work according to the program in our DNA and RNA.

Here we present you just a few examples of nanorobots, that are already prototyped in laboratories around the World.

In Mainz, Germany, a group of scientists have created a prototype of an engine that consists of just one atom. It transforms heat energy, transmitted by laser, to its movement, similarly to the piston engine.

In Ohio, Unite States of America, mechanical engineers have used nanorobots and technology called "DNA-origami" to fold DNA into 3D shapes at nanoscale. Such shapes will become parts of more complex nanorobots, so similar machines construction principles could be used for building nanorobots by other nanorobots.

In Zurich, Switzerland, scientists have created nanofins that could swim through the biological liquids (such as blood) on the speed of 5 cm/hour. Such nanofins could be attached to a medicament in order to deliver it to the needed destination in the human body, for example, to cancer cells.

In Cambridge, England, "Ant nanoengine" has been developed in the University of Cambridge. It could provide force that is 100 bigger than its own weight, similar to the strength of ants that can carry weight significantly bigger than ant itself.

This is just a small list of latest achievements in the nano-labs that could revolutionary change our lives in the near future. The use of nanorobots is also very promising in the following situations:

In the cancer treatment, because nanorobots can detect and destroy cancer cells in an extremely and effective way.

In medicine delivery. Medics will control the process of the delivery of medicine directly to the needed cells of human body.

In medical scan and visualization. Nanorobots could travel within the human body and provide unlimited possibilities for medical scan and visualization of the body and its parts, detecting and effectively preventing large number of diseases, such as cancer and diabetes.

In information storage. Engineers have successfully tested data storage using DNA and nanorobots. In Harward, engineers have proved that just one gram of DNA could store about 700 terabytes of data, making the World record in information storage.

In renewable energy. Scientists are working on renewable energy sources using nanorobots to achieve better efficiency and less energy consumption.

Super strong materials. Scientists from the University of California has developed a new nano-material that is built by nanorobots using the same technique as Gustave Eifel has used for constructing his famous Tower, located in Paris. Such super strong nano-material became one of the strongest and, at the same time, lightest in the whole History.

This is just the beginning of a period in which nanorobots can be a great help in solving the problems affecting Mankind. It is estimated that the nanotechnology market could reach 75,800 million dollars in 2020, with a tendency to continue growing. Will it happen or not, we will see very soon.
