...assive" targeting of the tumor. Tumors grow extra blood
vessels in a process called angiogenesis. These angiogenic vessels are very porous, which allowed the quantum dots to leak out and accumulate at the tumor sites, where they could be detected by fluorescence imaging. The scientists then conjugated t...
