Atomically-precise Au(Lys-Cys-Lys) nanoclusters for radiation sensitization.

Radiotherapy is a leading method for cancer treatment, effectively eliminating cancer cells but often causing collateral damage to surrounding healthy tissue. Radiosensitizers aim to enhance the therapeutic effects of radiotherapy while minimizing harm to normal cells. We recently reported atomically-precise gold nanoclusters, Au(Lys-Cys-Lys), synthesized via a photochemical method coupled with a novel accelerated size-focusing procedure.
