How is nanotechnology currently used in medicine?
One application of nanotechnology in medicine currently being developed involves employing nanoparticles to deliver drugs, heat, light or other substances to specific types of cells (such as cancer cells). This technique reduces damage to healthy cells in the body and allows for earlier detection of disease.
What is nanotechnology and its applications?
Nanotechnology is being used in developing countries to help treat disease and prevent health issues. In industry, applications may include construction materials, military goods, and nano-machining of nano-wires, nano-rods, few layers of graphene, etc.
What are nanoparticles used for in medicine?
Researchers today are able to encapsulate medicine in nanoparticles , the size of viruses. The nanoparticles are effective for drug delivery—the delivery of the medicine to the body—because they can very precisely find diseased cells and carry the medicine to them.
What are the future uses of nanotechnology?
In the future, nanotechnology could also enable objects to harvest energy from their environment. New nano-materials and concepts are currently being developed that show potential for producing energy from movement, light, variations in temperature, glucose and other sources with high conversion efficiency.
Can nanotechnology cure diseases?
With the use of nanotechnology , scientists hope to prevent illness , more quickly diagnose, control disease and treat disease with fewer side effects, and create better medical aids such as more compatible prosthetics. Nanoparticles and surfaces made of nanostructures are used in many areas of healthcare research.
What are the risks of nanotechnology in medicine?
What are the possible dangers of nanotechnology ? Nanoparticles may damage the lungs. Nanoparticles can get into the body through the skin, lungs and digestive system. The human body has developed a tolerance to most naturally occurring elements and molecules that it has contact with.
