If you are a fan of sci-fi movies, you might have already encountered the term nanotechnology. Although the things you know about nanotech are all based on the big screen, the fact remains that this breakthrough in modern technology introduces a lot of opportunities for us, humans, to improve our way of living. Perhaps the most important application of nanotechnology is to use it in the field of medicine. Based on ongoing researches, nanotech in medical science could just be the answer to cure the uncurable, or even improve the state of well-being of a person.
The use of nanotechnology in medicine offers some exciting possibilities. Some techniques are only imagined, like the ones that you have watched in Marvel movies where Iron Man uses nanotech to develop his armors and weapons. Other nanotech studies are at various stages of testing at this point, which are already producing positive results for further exploration.
Nanotech As A Life Saver: Finally A Cure To Cancer?
There is no doubt that science will advance towards a stage that finally addresses the issues about cancer cure. Scientists were able to come up with wearable technology, so the sky is just the limit for us to discover bigger things along the way.
Nanotechnology in medical science involves applications of nanoparticles, or perhaps the use of manufactured nano-robots, that are developed to repair things at a cellular level. This kind of approach in nanotechnology revolutionizes the way medical practitioners diagnose and cure untreatable diseases. The current techniques used today to treat damages to the human body require sizeable tools that fail to see the smaller picture. Believe it or not, the concept of nanoparticles to perform bodily operations at a microscopic level is not a prankdial, this is the real deal!
One vital application of nanotechnology in medicine that is still being developed today is the use of nanoparticles to deliver drugs or other substances to specific types of cells for treatment. This approach probably works best in fighting cancer cells. Major surgery and chemotheraphy remain as the top choices to treat cancer, but these methods often damage other parts of the body that are rather healthy. In nanotech, only the damaging cancer cells are targetted.
Nanoparticles are engineered in such a way that they are only attracted to defectivecells, which allows direct treatment of those cells. This technique reduces damage to healthy cells in the body and allows for earlier detection of disease. As an example, medical scientists at North Carolina State University are now developing a method to deliver cardiac stem cells to damaged heart tissue, wherein nanovesicles are attached to the stem cells so that they are properly delivered to an injured tissue subject for repair.
