Nanotechnology's impact in medicine field

Nanotechnology plays a major role in field of medicine . The usage of nanotechnology provides interesting possibilities . Well , Nanotechnology in medicine field the applications of nano particles that are currently under development. Not only that, a longer range research that involves the usage of manufactured nano-robots to make repairs at the cellular level . The use of nanotechnology could change radically the way we detect and treat the damage in our body and the disease the future. There are many applications of nanotechnology in the medicine field . The operation at nano scale allows
exploitation of physical properties different from those observed at micro scale such as volume/surface ratio. Here are some of the various examples that are the stated below here.

Medical Application : Drug Delivery

This application is being developed in the medicine field which uses nano particles to deliver drug , heat , light and other substances . The particles are engineered in order for them to be attracted to the diseased cells. which provides a  direct treatment of those cells. Not only that ,  this technique also helps decreases the  damage to healthy cells in the body and allows it for earlier detection of disease.

Medical Application : Nano medicine diagnostics

For the past few decades , imaging turned out to be an essential tool in the diagnosis of disease. The advances of the magnetic resonance and computer tomography are extraordinary , but not only that nanotechnology assures sensitive and accurate tools for in vitro and in vivo diagnostics that are far ahead of today’s state-of-the-art equipment. Well ,  the utmost target is to allow the physicians to identify the disease as soon as possible. The Nanotechnology field  is believed to make diagnosis possible at the cellular and even the sub-cellular level.

The Quantum dots had taken the step from pure demonstration experiments to real applications in imaging. In recent years, the scientists have discovered that these nano crystals allows researchers to study and comprehend cell processes at the level of a single molecule. This drastically enhance the diagnosis and treatment of cancers.

The fluorescent semiconductor quantum dots prove to be extremely beneficial for medical applications, such as high-resolution cellular imaging. Whereas , the quantum dots  could change medicine radically but the drawback is that most of it are toxic . Well , recently studies has shown protective coatings for quantum dots may eliminate toxicity.
