Abstract
Multifunctional low-generation dendrimer-entrapped gold nanoparticles (Au DENPs) were designed and synthesized. The formed Au DENPs modified with an arginine-glycine-aspartic peptide and labeled with 99mTc possess a uniform size distribution, desirable colloidal stability and biocompatibility, and can be used as a promising nanoprobe for targeted SPECT/CT imaging of αvβ3 integrin-expressing tumors.
