[ 1 ] - Enhancement of radio-sensitivity of colorectal cancer cells by gold nanoparticles at 18 MV energy
Objective(s): Taking advantage of high atomic number of gold nanoparticles (GNPs) in radiation dose absorbing, many in vitro and in vivo studies have been carried out on using them as radio-sensitizer. In spite of noticeable dose enhancement by GNPs at keV energies, using this energy range for radiotherapy of deep-seated tumors is outdated. The aim of the present work was to examine the effect ...
[ 2 ] - Carbon Nanotubes as Near Infrared Radiation (NIR) Molecules for Cancer treatment
Introduction: The photo-thermal therapy by nanoparticles has been recently known as an efficient strategy for the cancer treatment. Carbon nanotubes (CNTs) have been extensively studied in biomedical application due to the easy uptake and high permeability in the cells, biocompatibility in biological environments and also their unique electrical, thermal properties. They genera...
