Role of Nanotechnology in Medical Imaging

Nida Tabassum Khan

Imaging methods have been used for decades for cell/tissue imaging in diagnostics. However the results of conventional imaging techniques were less distinctive and transparent because of the use of unstable organic dyes as contrast agents. These dyes offered low photo stability and quantum yield resulting in poor quality images. However with the advent of nanotechnology, field of medical imaging has revolutionized immensely. Application of different nanomaterials such as silica nanoparticles, quantum dots, gold nanoparticles, etc. have overwhelmed many of the restrictions of conventional contrast agents employed in imaging and thus enhances the performance potential of the existing diagnostic tools.
