DSSC-affiliated researchers from Carnegie Mellon have joined forces with colleagues at the Instituto de Tecnica Aereoespacial (INTA) in Madrid, Spain, to build a MEMS-based sensor for tracking magnetic nanoparticles used to tag tissue scaffolds.
The sensor was conceived at INTA for use in identifying extraterrestrial magnetic materials. Carnegie Mellon's Michael McHenry and David Laughlin, and Marina Diaz-Michelena, a researcher in payloads and instrumentation and head of the Space Magnetism Unit at INTA (Spain's equivalent of NASA) supervised a Carnegie Mellon senior capstone design project to demonstrate sensor potential for biomedical engineering applications.
"We are developing new tools to track magnetic nanoparticles that can be used to add functionality on tissue scaffolds for regenerative medicine," said McHenry, a professor of materials science and engineering and biomedical engineering.
The work was featured on the April 2011 cover of the Journal of Applied Physics. Materials science and engineering graduate students Nick Jones, Kate McNerny and Vincent Sokalski, who all participate in DSSC research, were co-authors on the paper.
