Newly created synthetic particles that mimic red blood cells may one day carry drug molecules and/or oxygen through bloodstreams, according to researchers linkurl:writing;http://www.pnas.org/cgi/doi/10.1073/pnas.090712710 in this week's issue of the __Proceedings of the National Academy of Sciences__ (__PNAS__). What's more, the team of scientists in Michigan and California say the particles could also be used to improve the resolution of magnetic resonance imaging.
"It's a very nice paper and very exciting work," linkurl:Krishnendo Roy,;http://www.bme.utexas.edu/faculty/roy.cfm a biomedical engineer at the University of Texas at Austin who wasn't involved with the study, told __The Scientist__. "The beauty of their method is its simplicity." University of California, Santa Barbara, chemical engineer linkurl:Samir Mitragotri;http://drugdelivery.engr.ucsb.edu/Samir.html led the team of scientists and told __The Scientist__ that the blood cell-like particles could evolve into useful tools in the clinic. "What we got very excited...
