An Essay on nanotechnology and drug delivery - Chemistry Translates
Nanotechnology, in its traditional sense, means building things from the bottom up with atomic precision using techniques and tools being developed today to make complete high performance products. Nano-scale activities take place around us every day in the natural world — photosynthesis and the essay on nanotechnology of energy in the human body to name just two, essay on nanotechnology.
It is a highly multidisciplinary field drawing from other fields of science as well. The comparative size of a nano meter to a meter is the same as that of a marble to the size of the earth. In the mid nineteenth century, physicist Richard Feynman gave a lecture focused on the field of miniaturization and how he believed man would create increasingly smaller, essay on nanotechnology, powerful devices.
In the latter part of the nineteenth century, K, essay on nanotechnology. Eric Drexler introduced the term nanotechnology. He talked about building machines on the scale of molecules-a few nano meters wide: motors, robot arms, and even whole computers far smaller than a cell. Drexler spent the next ten years describing and analysing these incredible devices, and responding to accusations of science fiction. Scientific research in this regard really essay on nanotechnology only over the last decade.
A lot of everyday products use nanotechnology. Sunscreens made with nano-particles of zinc oxide or titanium oxide no longer leave the whitish colour their predecessors did because the nano-particles are less visible. By coating fabrics with a thin layer of zinc oxide nano-particles, clothes are being created now that give better protection from UV radiation. Some clothes even have nano-particles in the form of little hairs or whiskers that help repel water and other materials, making them stain—resistant.
Adding nano-particles to scratch-resistant coatings has increased the resistance of these coatings to chipping and scratching and the uses of this are widespread covering almost everything from cars to eyeglass lenses. Antibacterial bandages using silver nano-particles are heill Still, this market is just in its nascent stage.
Today, essay on nanotechnology, more than 13, patents registered with the U. The most immediate challenge in nanotechnology is that we need to learn more about materials and their properties at the nano-scale, essay on nanotechnology. Some doctors worry that the nano-particles are so small, that they could easily cross the blood-brain barrier, a membrane that protects essay on nanotechnology brain from harmful chemicals in the bloodstream.
Like computers or electricity before it, nanotechnology will offer greatly improved efficiency essay on nanotechnology almost every facet of life. As a general-purpose technology, it will be dual-use, meaning it will have many commercial uses and it also will have many military uses—making far more, essay on nanotechnology.
powerful weapons and tools of surveillance. Thus it represents not only wonderful benefits for humanity, but also grave risks. Theoretically, it might be able to make us smarter, stronger and give us other abilities ranging from rapid healing to night vision. Is this a path we would like to take? It could also have an impact on the world economy at large. If molecular manufacturing becomes a reality, it would mean we could build anything at the click of a button.
What would then happen to all the manufacturing jobs? If you can create anything using a replicator, what happens to currency? Would we move to a completely electronic economy? Would we even need money at all? Perhaps these concerns are at best premature, and probably unnecessary.
Even so, nanotechnology will definitely continue to impact us as we learn more about the enormous potential of the nano-scale, essay on nanotechnology. Your email address will not be published.
