Enhanced cellular toxicity was observed using X-ray irradiated nanoparticle drug carriers (NDC) consisting of doxorubicin (DOX) conjugated to DNA strands attached to the surface of gold nanoparticles. Kinetic studies showed that X-rays, acting as a triggering modality, generated reactive oxygen species to break DNA strands and release DOX.
