Nano Medicinal Chemistry
Many researchers assign ethylene glycol molecules to nanoparticles that bring therapeutic drugs to cancer tumors. The ethylene glycol molecules break white blood cells from recognizing the nanoparticles as foreign materials, allowing them to circulate in the blood stream extended enough to attach to cancer tumors. However researchers at the University of California, San Diego trust that they can upturn the time nanoparticles can circulate in the blood stream. They are covering nanoparticles holding therapeutic drugs with membranes from red blood cells and have exposed that these nanoparticles will circulate in a mouse's blood brook for almost two days, instead of the few hours observed for nanoparticles using ethylene glycol molecules.
