Ultrasmall (<2 nm) gold nanoclusters are used by Xing-Jie Liang, Jianping Xie, and colleagues as a new type of metabolizable and efficient radiosensitizers for cancer radiotherapy, on page 133. In particular, the gold nanoclusters consisting of 25 gold atoms and 18 thiolate ligands show attractive features for cancer radiotherapy including preferential tumor deposition, strong radiotherapy enhancement, and efficient renal clearance.
