Unraveling the cell-type dependent radiosensitizing effects of gold through the development of a multifunctional gold nanoparticle

A tri-functional gold nanoparticle (AuNP-DP) conjugated with polyethylene glycol and two short bioactive peptides. Combined with radiation, comparatively low AuNP-DP concentrations significantly enhanced the radiation sensitivity of MDA-MB-231 breast cancer cells, both in vitro and in vivo.206
