From Nanowerk News:
Nanoparticles are particles that are smaller than 100 nanometers. They are typically obtained from metals and, because of their tiny size, have unique properties that make them useful for biomedical applications. However, without treatment to make their surfaces biologically inert, their effectiveness is severely limited.
Researchers led by Kazuhiko Ishihara at the University of Tokyo have pioneered the use of MPC polymers to modify the surfaces of nanoparticles.
In a recent article published in the journal Science and Technology of Advanced Materials (“Cytocompatible and multifunctional polymeric nanoparticles for transportation of bioactive molecules into and within cells”), they reviewed current ways in which polymeric nanoparticles can be used to transport a type of small nanoparticles called quantum dots into cells.
