Title: Nanoparticles for In Vivo Tracking
Description: This confocal laser scanning microscopy image shows kidney cancer cells (cell nuclei in blue, cell skeleton in green) labeled by phosphorylcholine-coated semiconducting polymer nanoparticles (red). The phosphorylcholine coating allows very efficient and rapid endocytosis into the cell (about 30 minutes) while the semiconducting polymer allows durable and long-lasting fluorescence to measure multiple biological processes unique to cancer cell sub-types. Cells labeled with this nanoparticle can be imaged in vivo, with only a 35 percent decrease in fluorescence intensity after 12 days.
