"It's a very nice paper and very exciting work," linkurl:Krishnendo Roy,; 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; 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...
