In this article we will discuss about Nano Medicine:- 1. Meaning of Nano Medicine 2. Advantages of Nano Medicine 3. Disadvantages.
Meaning of Nano Medicine:
The application of nanotechnology in medicine is often referred to as Nano medicine. Nano medicine is the preservation and improvement of human health using molecular tools and molecular knowledge of the human body. It covers areas such as nanoparticle drug delivery and possible future applications of molecular nanotechnology (MNT) and Nano-vaccinology.
The human body is comprised of molecules. Hence, the availability of molecular nanotechnology will permit dramatic progress in human medical services. More than just an extension of “molecular medicine,” Nano medicine will help us understand how the biological machinery inside living cells operates at the Nano scale so that it can be employed in molecular machine systems to address complicated medical conditions such as cancer, AIDS, ageing and thereby bring about significant improvement and extension of natural human biological structure and function at the molecular scale.
Nano medical approaches to drug delivery centre on developing Nano scale particles or molecules to improve drug bioavailability that refers to the presence of drug molecules in the body part where they are actually needed and will probably do the most good. It is all about targeting the molecules and delivering drugs with cell precision.
The use of Nano robots in medicine would totally change the world of medicine once it is realized. For instance, by introducing these Nano robots into the body damages and infections can be detected and repaired. In short it holds that capability to change the traditional approach of treating diseases and naturally occurring conditions in the human beings.
Advantages of Nano Medicine:
1. Advanced therapies with reduced degree of invasiveness.
2. Reduced negative effects of drugs and surgical procedures.
3. Faster, smaller and highly sensitive diagnostic tools.
4. Cost effectiveness of medicines and disease management procedures as a whole.
5. Unsolved medical problems such as cancer, benefiting from the Nano medical approach.
6. Reduced mortality and morbidity rates and increased longevity in return.
Disadvantages of Nano Medicine:
1. Lack of proper knowledge about the effect of nanoparticles on biochemical pathways and processes of human body.
2. Scientists are primarily concerned about the toxicity, characterization and exposure pathways associated with Nano medicine that might pose a serious threat to the human beings and environment.
3. The society’s ethical use of Nano medicine beyond the concerned safety issues, poses a serious question to the researchers.
