Nanomedicine – The Latest Buzz In The Field Of Medicines!

Technology and medical science has evolved at a greater pace as compared to the evolution of human beings. Every now and then, there are developments. One of the latest in the medical science is the Nanomedicine. Man ever since has understood the nuances of life have been worried about the day when he would have to face death. He understands that every thing that is born would die, but doesn’t want to acknowledge this fact. Man is trying to explore every possibility to sustain the life. He wants to defeat death and wants some kind of remedy, which would help humans being youthful and alive forever.

Nanomedicine is the output of the nanotechnology. This could be understood as a very tiny step towards human desire to live. There are so many diseases and there are cures as well. However, no one cure could be 100% and side effects should be expected. With the use of Nanomedicine, the side effects of the medicines and therapy conducted for a disease could be reduced and success rate of the effectiveness of the same could be increased. This simply means that Nanomedicine is a booster that would help make the tools of medical science even stronger than before.

The principle on which this medicine works is, this technique would aim at utilizing nanoparticles, sensors after a detailed diagnosis and the MEMS (micro-electro mechanical system) and then monitor & observe the vivo bio chemical activities.

The advantages of Nanomedicine are listed below –

By just modifying the genetic material diseases as deadly as caner could be taken care off. Disease elimination will become normal. With this, before the symptoms are on the surface the disease could be diagnosed. It administers drugs. Uses tools that can gauge the effectiveness of the treatment

Nanomedicine

NANOMEDICINE in present century is the potent output of nanotechnology. It could changes the path of doctors to treat various life threaten diseases. Nanomedicine could increases effectiveness and reduces side effects unlike the other painful therapy. The basic principles of this technique are based on targeted drug delivery using nanoparticles, proper diagnosis using sensors and micro electro mechanical system (MEMS) and to monitor in vivo biochemical activities. Nanotechnology has provided the different important tools (nanomedicine) like nanoshells, nanomachines, nanobiosensors, nanofilms, nanocapsules and nanotubes for improvement of human health.

Nanoshell is made up of inner core of glass and coated with gold shell. It is 1000 times less than the actual size of human hair. Nanoshells are used in the treatment of solid tumors. After injecting the nanoshells deeply in the tumor, a dose of infra red radiations in the targeted area is given for 10-30 seconds. Nanoshell here performs dual role, either acts like scalpel or get heated by IR radiations to kill the cancerous cells. It is the work of Jennifer and Naomi halas at Rice University. Nanoshell avoids the unpleasant side effect of chemotherapy. The nanomachine can be also called as LAB ON CHIP that continuously monitors the level of biochemicals in the bloodstream and in response would release appropriate drugs. E.g. such device monitors and adjusts the insulin level in insulin dependent diabetes. The nanobiosensors & MEMS are used for pathogen and contamination detection. Person facing the problems of vitamin and nutrient deficiency could overcome by nanocapsule enriched with specific supplements.

The traditional system of drug delivery loss drugs from the body by means of water. Applying nanofilm coated with multiple drugs may be an effective approach for delivering drugs locally for longer duration. This technique would eliminate unrequited surgeries.

E.g. the dexamethasone coated nanoscaled polymer film when implanted in mice; it suppresses the cytokines of immune system. This could allow the successful skin grafting. Silver, for a long time is known for its potent antimicrobial activities. It controls microbial infection. It is reported to improve wound healing & is non toxic to human tissue. Based on these properties, nanocrystalline silver films coated with silver particles (average size 15 nm) have been developed. These stripes could be directly applied on the wounds. After contact with water, these stripes release silver particles in the form of silver radicals that penetrates in the wounded area to improve healing.

Scientist have shown for the first time that carbon nanotubes make an ideal scaffold for the growth of bone tissue because it has high mechanical strength, excellent flexibility and low density. It also mimics the role of collagen (the natural composite of bone) as a scaffold for the growth
