The use of Nanotechnology in medical imaging



Nanotechnology is currently being realistic to innovative methods of medical imaging. The development of imaging at the nanoscale has the ability to enhance the field of medicine by providing more detailed images of cellular processes. Current methods of medical imaging is being adapted to increase their potential at the nanoscale as well as being used as contrast agents for tracking injected nanoparticles in the body.

Research is currently proceeding in applying the technology to stem cell transplants and for the diagnostic imaging of early-stage diseases.

Nanotechnology and Nuclear Magnetic Resonance (NMR)

Nuclear Magnetic Resonance is a technique that adventures the magnetic properties of atomic nuclei to form medical images through Magnetic Resonance Imaging (MRI). Atomic nuclei in a magnetic field absorb and emit electromagnetic radiation, with the resonance frequency of a substance being directly proportional to the strength of the magnetic field.

The use of MRI is frequently to obtain images of various organs in the body. Nanotechnology provides the latent for medical imaging through NMR at the nanoscale. More detailed images can be produced by aligning the atomic nuclei in a nanostructure which supplies a large magnetic field that is 10,000 times bigger than the magnetic field of Earth.

Nanotechnology and Stem Cell Imaging

Medical imaging through nanotechnology is also animation useful for tracking transplanted stem cells. Medical imaging of stem cells requires added contrast agents. Current research is focused on evaluating various nanoparticles with unique optical and magnetic properties that can provide real-time tracking of transplanted stem cells. Along with traditional fluorescent imaging and MRI, nanoparticles have also been used to progress another method of nanoscale medical imaging, photoacoustic imaging.

A practical example of nanotechnology being employed for stem cell imaging is the use of iron oxide nanoparticles for tracking neural stem cells in patients with brain trauma. Stem cells have the potential for regenerating damaged brain tissue.

The use of nanotechnology in disease diagnosis and molecular imaging:


One of the main current focuses of research in medical diagnostics is molecular imaging. Molecular imaging can identify the disease at an early stage, provide fundamental information on pathological processes and can be applied to follow the efficacy of therapy.

Global Nanotechnology in Drug Delivery Industry

Image
 Representing the developed world, the United States will maintain an 18.3% growth momentum. Within Europe, which continues to remain an important element in the world economy, Germany will add over US$3.9 Billion to the region’s size and clout in the next 5 to 6 years. Over US$3.4 Billion worth of projected demand in the region will come from the Rest of Europe markets. In Japan, Nanocrystals will reach a market size of US$3.5 Billion by the close of the analysis period. As the world’s second-largest economy and the new game-changer in global markets, China exhibits the potential to grow at 25.6% over the next couple of years and add approximately US$26 Billion in terms of addressable opportunity for the picking by aspiring businesses and their astute leaders. Presented in visually rich graphics are these and many more need-to-know quantitative data important in ensuring the quality of strategy decisions, be it entry into new markets or allocation of resources within a portfo...

How is Nanotechnology useful?

Image
Nanotechnology is a measure of science and technology about the control of matter on the atomic and molecular scale. We know that nano deals with matter on an appropriately small scale - larger than atoms and molecules, but smaller than a breadcrumb.  Nanotechnology  is often named general technology as its advanced kind is having a significant impact on nearly all areas of industries, technology, research, and development. It suggestions safer, higher designed and smarter products for infrastructure industries, agriculture, transportation, and medicine generally. Nanotechnology will be capable of building products cleanly, cheaply, and rapidly.  Let us look as some uses and applications of Nanotechnology are: Medicine:  People are doing many dissimilar types of work in the field of nanotechnology. Most current work looks at the creation of  nanoparticles  that have different properties, such as the way they scatter light, absorb X-rays, ...
