However, some types of tumor respond little or hardly at all to radiation. If it were possible to make tumor cells more sensitive, treatment would be more effective and gentler. Empa and researchers have now succeeded in using metal oxide nanoparticles as "radiosensitizers" - and in producing them on an industrial scale. Today, various treatment methods are available for cancer that can complement each other.
