Nanotechnology applications in the field of Health and Medicine


Every day there is a lot of inventions coming into a part of our lives without any procrastinations with the help of advanced research on science and technology. In that Nanotechnology is one of the highly precision technical support where it booms all the fields with fruitful results like Industries, Electronics, Environment, Energy, Space, IT sector, Health and Medicine. Nano metre is one billion times smaller than one metre (I.e. 10 ^ -9). Nanotechnology is engineering at the atomic and molecular scaling often deals with the size of 0.1 nm to 100 nm If we redesigned an object in atomic and molecular level of scaling Nano size, then the objective of that particular thing will be implemented by acquiring more strength in its structure, and achieved enhanced functions as per our requirements with in compact package.
             
      Even it has its impact on all sectors, specially now we are dealing the enormous applications of this tremendous technology in the field of health and medicine. The concept of targeted drug delivery will be opening a new chapter especially to end the problem of cancer patients. For example, if we find out a tumour in a specific area of human body, to treat that caner cells we depend on the traditional methods of chemotherapy and radiotherapy orally. Because of these methods patients feel more side effects like losing hair, becoming weak and sick. This kind of treatment methods and Medicine are too expensive to use for the betterment of cancer patient's health. Instead of that, if we use targeted drug delivery method where the Nano capsules contain the effective antibodies which will be designed such manner to activate with the energy of chemotherapy Nano miniaturized particle located inside the capsules, it will detect and attached with the cancer cells to destroy them.

           It is dealing with one more contrivance of neuron degeneration. It means to create a network of random neurons with new connections and placing it in a compact pack of neuron set. If any part of brain damage occurs for that particular person this neuron set will be useful for degeneration of neurons with new functions and features with replacement of damage. This technology is helpful for the study of DNA and it's research, if we get brief idea about DNA of particular person with less time span, then we easily predict health issues of him which will be facing in the future. With this kind of estimation we start caring today onwards.

Now we are looking for the application of Magnetic Nano particles. The major function of these particles to destroy the tumours and clear blood clots in side the brain without going for surgery. With the help of Nano capsules, the Magnetic Nano particles reaches the effected area. Later we apply Magnetic fields outer side, the Magnetic Nano particles develop the required amount of heat to burn the tumour and clear the blood clots inside the brain with fewer efforts.

At the earlier detection of cancer and treatment for its prevention with the help of Nano technology is Biomedical imaging. Quantum dots are the luminescent Nano particles. These will help us to recognize a very small blockage and a minuted hole at its starting stages inside the heart vessels. In the study of Ophthalmology, remove dead cells and blood clots inside the eye, the instrumental equipment which is made with Nanotechnology is very useful.
           Still, the research is going on how much amount of Nano drug is enough for clear the tumours, blockages, clots inside the body and after completion of its job on targeted area, it should be coming outside without interacting on other biological actions otherwise it will create new problems. If successfully the above mentioned inlaid problems overcoming by these Nano medicine, then really Nanotechnology is escorting human lives.
