Golden Nanotubes Detect Tumor Cells, Map Sentinel Lymph Nodes, University of Arkansas Study

(PhysOrg.com) -- Biomedical researchers at the University of Arkansas in Fayetteville and the University of Arkansas for Medical Sciences (UAMS) in Little Rock have developed a special contrast-imaging agent made of gold-coated carbon nanotubes that is capable of molecular mapping of lymphatic endothelial cells and detecting cancer metastasis in sentinel lymph nodes. The findings from this study, which was led by Jin-Woo Kim, Ph.D., M.S., University of Arkansas, and Vladimir P. Zharov, Ph.D., D.Sc., M.S., UAMS, were published in the journal Nature Nanotechnology.
