Query: Ultrasmall Au10-12(SG)10-12 Nanomolecules for High Tumor Specificity and
  Cancer Radiotherapy   Radiosensitizers can increase the local treatment efficacy under a relatively
low and safe radiation dose, thereby facilitating tumor eradication and
minimizing side effects. Here, we report a new class of radiosensitizers that
contain several gold (Au) atoms embedded inside a peptide shell (e.g.,
Au10-12(SG)10-12) and can achieve ultrahigh tumor uptake (10.86 SUV at 24 h
post injection) and targeting specificity, efficient renal clearance, and high
radiotherapy enhancement.
