Researchers develop novel gold-nanocluster-based tumor radiodynamic therapy

Radiotherapy (RT) is a primary method of tumor treatment. However, in clinical practice, radiotherapy still suffers from shortcomings such as serious side effects, limited efficacy, and tumor metastasis and recurrence due to the tumor microenvironment (hypoxia, low pH, high H2O2, etc.). Therefore, there is an urgent need to develop efficient, safe and low toxicity advanced tumor radiotherapy technology for clinical tumor treatment.
