The Enhancement of Breast Cancer Radiotherapy by Using Silver Nanoparticles with 6 MeV Gamma Photons

Abstract

The nanoparticles has use emerged to be highly promising for cancer therapy over the past few years, , most commonly the high photons therapy method(radiotherapy), which employs high photons absorbing with injected nanoparticles  for enhancing  the damage of tumors, the high photons therapy which employs nanoparticales that increase generate free radicals that is capable of tumor destruction. Last development in the field of nanoscience have seen the appearing of noble metal nanostructures with unique properties, well suited for applications in cancer radiotherapy. Metal nanoparticles has the phenomenon of enhanced dose absorption, thermal stability ,easy to detection and increasing the cross section of tissue  . Because using nanoparticles as enhanced photo-absorbing agents thus introduced  to enhance the efficiency of cancer radiotherapy. The easy synthetic of the silver nanoparticle as a colloidal solution   with unique   properties and the bio-targeting abilities of the silver nanoparticles make the radiotherapy method furthermore promising. In this project, we discuss the development of the radiotherapy method by injected silver nano particles as a colloidal solution  in vivo. i.e. using silver nanosparticles interacted with high energy of gamma photons.
