The importance and uses of nanotechnology in medicine
Nanotechnology in medicine
Nanomedicine is the medical application of nanotechnology , It ranges from the medical applications of nanomaterials to nano electronic biosensors , and applications of molecular , It is reserving and improving the human health by using molecular tools and molecular knowledge of the human body .
Nanomedicine involves the use of nanoparticles in the surgical and medical treatment of patients , and it is used for the treatment of diseases in living organisms .
Nanotechnology involves manipulating properties and structures at the nanoscale , It often involves dimensions that are just tiny fractions of the width of a human hair .
Nanotechnology is already used in the products such as the cosmetics and the sunscreens , the nanoscale materials in cosmetic products provide greater clarity or coverage , cleansing , and absorption .
Nano scale materials are used in antioxidant , anti-microbial , and other health properties in the sunscreens , the cleansers , the complexion the treatments , the creams and lotions , the shampoos , and specialized makeup .
Nanotechnology is used in cancer that can lead to breakthroughs in terms of detecting , diagnosing and treating various forms of cancer , Medical nanotechnology tools are more personalized , portable , cheaper , safer and easier to administer .
Nanotechnology will aid in the formation of molecular systems that may be strikingly similar to living systems , These molecular structures could be the basis for the regeneration or replacement of body parts that are currently lost to infection , accident , or disease .
Nanotechnology has been used in the early diagnosis of atherosclerosis , or the buildup of plaque in arteries and gold nanoparticles can be used to detect early-stage Alzheimer’s disease .
Quantum dots are semiconducting nanocrystals that can enhance biological imaging for medical diagnostics , when they are illuminated with ultraviolet light , they emit a wide spectrum of bright colors that can be used to locate and identify specific kinds of cells and biological activities .
These crystals offer optical detection up to 1,000 times better than conventional dyes used in many biological tests , such as MRIs , and render significantly more information .
Nanotechnology is used in the multifunctional therapeutics where a nanoparticle serves as a platform to facilitate its specific targeting to the cancer cells and delivery of a potent treatment , They minimize the risk to normal tissues .
The research is underway to use nanotechnology to spur the growth of nerve cells such as in damaged spinal cord or brain cells , Nanotechnology in medicine will benefit those that suffer from the heart disease , the respiratory problems and diabetes in the future .
Nanotechnology in medicine will be used to help in the fertility issues , the brain issues or malfunctions and even the reparation of senses .
