Cell-membrane coated nanoparticles light up two cancer biomarkers at once to give more complete picture of tumor

Cancer surgeons may soon have a more complete view of tumors during surgery, thanks to new imaging agents that can illuminate multiple biomarkers at once, University of Illinois Urbana-Champaign researchers report. The fluorescent nanoparticles, wrapped in the membranes of red blood cells, target tumors better than current clinically approved dyes and can emit two distinct signals in response to just one beam of surgical light, a feature that could help doctors distinguish tumor borders and identify metastatic cancers.
