To boost this approach, researchers at the University of California, Los Angeles, have developed a method for creating supramolecular assemblies of gold nanoparticles that function as highly efficient photothermal agents of a size designed to optimize their delivery to tumors. Hsien-Rong Tseng, a member of the Nanosystems Biology Cancer Center, and his colleagues reported their work in the journal Angewandte Chemie International Edition.

Shuming Nie, the principal investigator of the Emory University and Georgia Institute of Technology Center of Cancer Nanotechnology Excellence, led the research, which was published in the journal ACS Nano.
