Radioactive ( ⁹⁰ Y) upconversion nanoparticles conjugated with recombinant targeted toxin for synergistic nanotheranostics of cancer

Significance Emerging cancer nanotechnology enables targeted delivery of substantial payloads of drugs to cancer sites with concomitant reduction of side effects due to the lesser accumulation in the critical organs. This prompts loading of nanocarriers with therapeutic cargo and contrast agents, allowing combined cancer therapy and tumor visualization, respectively. This paper reports the realization of such combined therapy using conjugates of...
