Chitosan nanoparticles deliver Cy5.5-labeled siRNA to the tumor tissue preferentially. Control or Cy5.5-labeled siRNA was administered to the mice with or without a tumor in the femur and Cy5.5 signal was measured by using IVIS 200. An increase in Cy5.5 signal was observed in the femur in the tumor group compared with the nontumor group (reproduced from ref. 28 with permission from Oncotarget)
