Nanoparticles could provide easier route for cell therapy

Physics researchers may have developed a way to use laser technology to deliver drug and gene therapy at the cellular level without damaging surrounding tissue. The method eventually could help patients suffering from genetic conditions, cancers and neurological diseases. A significant advantage of the new method is that the near-infrared light absorption of the nanoparticle can be used to selectively amplify interaction of low power laser with targeted tissue and "laser induced-damage to non-ta...
