Antitumor effect of nanoparticles and nanogels on nude mice bearing U87MG cells subcutaneously were studied in vivo. Values of tumor weight (a) and body weight (b) changes are expressed as Mean ± SD (g, n = 5). Quantification of Au in tumor site was investigated by ICP-MS (c). The nude mice were administered via i.v. injection every 3 days. All of the data are reported as the means ± S.D. Macroscopic images of resected tumors at the conclusion of the experiment​ (d).
